The SeisNetWatch system is a three-tiered distributed system of agents, server, and front-end client. Agents collect data and control the acquisition software and communicate over the network to the server. The server is the centralized decision making tool that receives the agent's messages and passes on filtered data to the client.
The client is provided as a Java Applet and Application and the NSI server is a Java Application. The Collection and Control Agents may be written in C++ or Java. The collection agents provided for COMSERV and Earthworm are written in C++ and monitor data from comserv shared memory and datalog files and Earthworm WAVE_RING buffers, respectively. The communications between the agents and the SeisNetWatch server (NSI server) are accomplished using the CORBA Event Service and communication between the client and the NSI are via CORBA objects. If you are interested in running this software, please contact us.
At client startup, the agent obtains a CORBA object from the NSI server. After obtaining a link, it downloads information from the NSI server for initialization and begins operation. One of the key parameters passed in the initialization is the Refresh Rate which governs how often the SeisNetWatch app asks for updates from the NSI.
Note for sites running a firewall on the NSI host: Since the GUI clients open connections back to the NSI server host, you must open up the host's firewall for the port number configured for this purpose. The 'orbPortNum' parameter for the NSI server specifies which port the clients connect on. Note that this cannot be port 80 if you are running a web server.
Running the SeisNetWatch GUI client as an application:
To run the GUI client as an application, a command like the following one is used:
java -Xmx256m -jar application.jarIf you would like to view the Map Tab and the OpenMap(tm) station display option (licensed from isti.com), a command like the following one is used:
java -Xmx256m -jar appWithOpenMap.jarThe specified ".jar" archive file must be available in the current-working directory. The path to a CORBA object reference file (as a local pathname or as a URL address) may be given as a parameter.
It can be helpful to make a shell script or a shell alias to launch the GUI as an application. Here is an example that launches the app using a URL to find the CORBA object reference file:
java -Xmx256m -jar application.jar http://www.isti.com/snw/gui_acceptor_ior.refThe application will also accept, on the command line, any of the GUI client parameters; "-v" or "--version" to show the program version information; "-h" or "--help" to show a help screen of information; or "--configFileName" to specify the configuration settings file to use. The "--configFileName" value may be a local pathname or a URL address--when a URL address is used, the default GUI Acceptor "IOR:" file will be "gui_acceptor_ior.ref" in the same web directory as specified in the URL.
Parameters on the application's command line must be preceded by
1 to 2 switch characters ('-' or '/'). Non-boolean
parameters must take one of the following forms: "name
value", "name=value" or "name:value". Boolean parameters
must take one of the following forms: "name", "name-",
"name0", "name1", "name=0", "name=1", "name=true", "name=false",
"name:0", "name:1", "name:true" or "name:false"; where no
parameter or '1' translates to 'true', and a trailing '-' or '0'
translates to 'false'.
If the OpenMap(tm) station display option is licensed from isti.com, the main screen shows a set of four tabs along the top, with the Stations Tab already in the foreground. Behind the Stations Tab is the Performance Tab, the Map Tab and the Subset Tab which the user may click on to bring to the foreground.
The station button is normally displayed with black text but it
will by default change to reverse video (white text with a black
background, see 'stationChangeColor')
if the Usage Level or Performance Level have changed within a
recent update from the NSI server. This is to indicate to the
end-user that something changed because on a cluttered screen, the
changes are not always apparent unless they are dramatic. If the
station's levels remain unchanged for a certain amount of time,
then the color will revert to normal (black). This time may be
specified as a parameter to the program (see 'stationColorChangeMS').
Clicking on the station box will also make its color revert to
normal (black).
A station button on the reactor panel
may be located by typing characters from the station name on the
keyboard. As each character is typed, the matching station button
is highlighted by a flickering white border. The full station name
(including a leading network code like "NN-") or the station code
without the network code may be entered. Station buttons may also
be located by repeatedly entering the first character of the
station code, which will result in the next matching station
button being highlighted with each keypress.
While a station button is highlighted, pressing the spacebar or
'Enter' key will display the station-detail page for the station.
The cursor-edit keys may be used to "navigate" the
currently-highlighted station button (these keys include:
cursor-up, cursor-down, cursor-left, cursor-right, PgUp, PgDn,
Home, End). Station buttons on the Performance
Tab may also be located via the keyboard.
Note that this tab can be disabled by setting the maxNumPerfValues
parameter value to '0'.
The Performance Tab provides the user with a way to see the performance of stations over time. To open this tab, simply click on it. It may also be viewed by right-clicking a station button on any reactor panel or by clicking on the "Performance" item on any Station Detail Tab. The Performance Tab displays the performance for the stations being monitored by the NSI server over time. The Y-axis is scrollable list of stations sorted in the same order as the Stations Tab. The Y-axis is scrollable if all of the stations can not be displayed on the screen. The X-axis is time increasing from left to right. To view a screen shot of this tab, click here.
This tab is updated as station updates are received from the NSI
server.
Each station name displayed on this tab is clickable as a
button. By clicking on the station, the user requests more
information about the station and is shown the Station
Detail Tab which is described in detail below.
Double-clicking on a performance bar will also show the Station Detail Tab for the station.
Right-clicking on a station or performance bar will display a
popup menu of options. Station buttons may be location via the
keyboard in the same fashion as for the Stations
Tab reactor panel.
On the performance tab, the time display may be zoomed in, either via the right-mouse-click popup menu or by left-mouse-button dragging. While the display is zoomed in, "Out" and "Reset" buttons will appear, which may be used to reverse the zoom of the display. On the right-mouse-click popup menu, the "Zoom Out" and "Zoom Reset View" items may also be used to reverse the zoom of the display.
The mouse-over tool-tips for the performance bars show the
"Start" time (minimum time for the performance level), "End" time
(maximum time for the performance level), the "Duration" (time
difference between the "Start" and "End" times), and the station
name. When station-detail items have a performance level lower
than the level specified by the perfToolTipLevel
parameter, the items will be shown in the tool-tips (up to a
maximum of 10 items).
On the bottom of this tab the "Start" time (minimum time for
every station displayed), "End" time (the time of the last update
to the display), and the "Duration" (time difference between the
"Start" and "End" times) are displayed.
Please note that this tab can be viewed only if the OpenMap(tm) station display option is licensed from isti.com and the JAR contains the necessary files (see the Running the SeisNetWatch GUI client as an application section above.) Also it is only supported when running the program as an application since external files are needed.
The Map Tab displays
all of the stations being monitored by the NSI server that was
contacted. On the right side of the map is a list of all of the
stations. By clicking on a station the user requests to select the
station. The selected station is indicated on the map with an
arrow. By double-clicking on the station the user requests more
information about the station and is shown the Station
Detail Tab (described below). The station names are listed
as NN-SSSSS where NN is the network code of the station and SSSSS
is the station name. The color of the symbol informs the user of
the Performance Level of the station. The meanings of the
Performance Level color values are described in the Symbol Key. To
view a screen shot of this tab,
click here.
When the Map Tab is displayed, the following items may be used in
the 'View' menu at the top of the frame:
The map may be configured by clicking on the "Layers" button,
which will bring up a "Layers" menu that allows all of the map
layers to be configured. Each individual layer may be turned on
and off by clicking on the layer-on/off (light bulb) button and
may be configured by clicking on the configure button.
# The default center latitude.
openmap.defaultCenterLat=37.3
# The default center longitude.
openmap.defaultCenterLon=-119.0
# The default scale.
openmap.defaultScale=10000000
# The default zoom in factor (must be < 1.0).
openmap.zoomInFactor=0.5
# The default zoom out factor (must be > 1.0).
openmap.zoomOutFactor=2.0
# The default station list background color.
openmap.stationListBackgroundColor=FFC0C0C0
[Back to Top]
Clicking on the "Performance" button will display a
performance-subset tab containing stations that match the
attribute's value. The tab will be similar in functionality to the
Performance Tab.
Clicking on the "Map" button will add (or update if already
present) a subset layer containing stations that match the
attribute's value to the Map Tab. The
selected subset layer is turned on and all other station layers
(subset and performance) are turned off. Note that this button is
only available if the Map Tab option is
enabled.
For "Agent" subset tabs, the subset reactor panel shows station
performance levels reflecting the voting of only those dynamic
parameters that were provided by the agent selected.
This tab display provides a list of static and dynamic information items about the station requested, including the station's name, performance level and usage level. Most of the other items come directly from the collection agents that feed the NSI server. Any item that affects the performance level for the station will have a colored circle to its left, where the color's meaning is described in the key at the bottom of the screen. The "lowest" performance level among the items will determine the performance level for the station. Any item names that appear blue in color may be clicked on to display help information about the item.
By clicking on a "Group" item, the user requests a Subset Tab that will display all stations
associated with the group. By clicking on the "Performance" level
of the station, the user requests more information about the
station's performance and is shown the Performance Tab (if enabled.) If you
click the tab icon circle the tab will be closed. If you
right-click the tab a popup menu will display options to close the
tab, close all tabs other than this one, close all tabs, close all
Station Detail Tabs, or
close all Subset Tabs (if any are present).
The right-click popup menu will also contain a selectable
"Favorite Tab" item, which, when selected, will prevent the tab
from being closed via the "Close all..." menu items.
Right-clicking on the station detail tab panel will display a popup menu of options.
A "plot" or "list" button may also appear to the left of an item.
This button may be clicked on to display a history plot or list
for the item. On history plots, the "Menu" button may be used to
display a menu of functions (print, save, etc.), and the plot
display may be zoomed using mouse-dragging actions (down and to
the right to zoom in; up and to the left to zoom out). The "Auto
Range" item on the menu may also be used to zoom out the axes so
that all data-points are visible.
Parameter: configFileName
This parameter may be used (in the HTML
document file that hosts the applet or on the command line for
program running as an applet) to specify the name of a
configuration settings file that may contain any of the parameters
below. This value may be the absolute URL address to the
file, or a relative path that is assumed to be in the same web
directory as the HTML document file that hosts the applet or, when
running as an application, this value specifies the location of
the configuration file. If no value is given for this
parameter then the program will look for the file "Client.ini" in
the same web directory as the HTML document file (if applet) or in
the local directory (if application). Any parameter values
specified in the HTML document, on the command line or in the User
Settings file will override those in this configuration
file. Note that if a pathname is specified using
Windows-style backslash ('\') separators, each backslash must be
"escaped" by preceding it with another backslash (i.e.,
"path\\Settings.ini").
Parameter: appletMode
On SeisNetWatch systems that feature
station usage levels, the applet mode parameter enables the usage
level control mode. (The status of this control mode is
displayed at the bottom of the main page of the client.) If
this parameter's value is "Control" then control mode is
enabled. The default value is "Observe".
Parameter: GUIAcceptorRefFile
This parameter specifies the location of
the file holding the IOR reference to the GUIAcceptor CORBA object
for the NSI server. The parameter value may be a full URL,
or, if not a URL, may reference a file using a relative path
(starting at the home directory of the HTML document containing
the applet). The default value is "gui_acceptor_ior.ref".
Parameter: programName
The program name string to be displayed
by the GUI client. The default value is "SeisNetWatch".
Parameter: consoleRedirectFileName
If a filename is given then the
"standard" output and "standard" error console output streams are
redirected into the given file. If the given filename is
"nul" then all console output will be discarded. If the 'userHomeSettingsFlag' parameter
is 'true' and this parameter is not set to an absolute path then
the file will be located in a ".snwclient" directory under the
current user's "home" directory. Note that if a
path/filename is specified using Windows-style backslash ('\')
separators, each backslash must be "escaped" by preceding it with
another backslash (i.e., "path\\ConsoleOut.txt"). The
default value is "" (empty string for no redirection).
Parameter: consoleRedirectAppendFlag
If true then output to the
console-redirect file ('consoleRedirectFileName')
will
be appended to any existing data in the file. If false then
any existing data will be erased. The default value is
'true'.
Parameter:
connectionRestartPopupFlag
If true then a popup is displayed before
restarting the connection. The default value is true (enabled).
Parameter: maxConnAttempts
The maximum number of initial
connect-to-server attempts allowed before an error message is
displayed. A value of zero corresponds to "infinity,"
meaning that connection attempts will continue indefinitely.
The default value is 25.
Parameter: userHomeSettingsFlag
When the program is running as an
application, this parameter may be set to 'true' to make the
program locate the User Settings and other configuration files in
a ".snwclient" directory under the current user's "home"
directory. This can be useful in installations where
multiple users are running the program and wish to have separate
settings. The default value is 'false' (put User Settings
file in program installation directory). This parameter
setting also affects the 'consoleRedirectFileName',
'programSingletonName' and 'commandFileName' parameters.
Parameter: settingsFileName
When the program is running as an
application, this parameter may be used to specify the name of the
User Settings file used to store parameters that may be changed by
the user. The parameter settings in this file will override
those in the configuration file. If the 'userHomeSettingsFlag' parameter
is 'true' and this parameter is not set to an absolute path then
the file will be located in a ".snwclient" directory under the
current user's "home" directory. Note that if a pathname is
specified using Windows-style backslash ('\') separators, each
backslash must be "escaped" by preceding it with another backslash
(i.e., "path\\Settings.ini"). The default value is
"Settings.ini".
Parameter: userSettingsFlag
If true then the loading and saving of
User Settings is enabled. The default value is true
(enabled).
Parameter: persistentTabsFlag
If true (and the userSettingsFlag parameter is true)
then the set of tabs displayed when the program exits will be
saved and then restored the next time the program is run.
The default value is false (disabled). This parameter may be
modified in the program via the "Settings"
window.
Parameter: showStationsTabFlag
If true then the main 'Stations' tab will
be displayed. The default value is true (displayed).
This parameter may be modified in the program via the "Settings" window.
Parameter: showPerformanceTabFlag
If true then the main 'Performance' tab
will be displayed. The default value is true
(displayed). This parameter may be modified in the program
via the "Settings" window.
Parameter: startupShowStation
This parameter specifies the name of a
station that the program will, at startup, load and display
(showing its station detail page). The type of display show
is determined by the 'showStationAtTime' parameter. The
default value is "" (no station shown at startup).
Parameter: showStationAtTime
This parameter specifies an
historical-snapshot time (in seconds after 1/1/1970 GMT) to be
associated with the 'startupShowStation' value. When a value
greater than zero is specified and a 'startupShowStation'
parameter-value is provided, an historical snapshot of the given
station will be displayed at startup. If a value of zero is
specified and a 'startupShowStation' parameter-value is provided,
a current station-detail page for the given station will be
displayed at startup. The default value is zero (current
station-detail page).
Parameter: autoPopLevels
When this parameter specifies one or more
performance level names (in a comma separated list with optional
quotes around the names), the program will "pop up"
subset-of-stations tabs of station buttons when all the stations
involved go to any of the specified performance levels (assuming
the tab is not already displayed). A subset will not be
"popped up" if the number of stations in the subset is less than
the 'minimumAutoPopCount' value. The default value is an
empty string (no "pop up" tabs).
Parameter: autoPopLevelsFlag
This optional flag parameter may be used
to control whether or not the program will "pop up"
subset-of-stations tabs of station buttons when all the stations
involved go to any of the performance levels specified by the
'autoPopLevels' parameter. A subset will not be "popped up"
if the number of stations in the subset is less than the
'minimumAutoPopCount' value. The default value is true
(enabled) if 'autoPopLevels' contains level names, otherwise false
(disabled). This parameter may be modified in the program
via the "Settings" window.
Parameter: onlyNewAutoPopFlag
If this parameter is true then tabs for
subset-of-stations sets with all stations at one of the
'autoPopLevels' performance levels will only "pop up" when the
condition occurs after the client has started. If false then
tabs for subset-of-stations sets that were already at one of the
'autoPopLevels' performance levels will be "popped up" when the
client starts. The default value is false ("pop up" tabs at
startup). This parameter may be modified in the program via
the "Settings" window.
Parameter: minimumAutoPopCount
This parameter sets the minimum number of
stations for any automatically "poped up" subset-of-stations tabs
(triggered via the "autoPopLevels..." parameters). The
default value is 2.
Parameter:
allStaUpdateSleepMS

time between updates of the station detail screens, in
milliseconds. The default value is 5000 (5 seconds).
This parameter may be modified in the program via the "Settings" window.
Parameter: stationColorChangeMS
This parameter specifies the length of
time that the color for a station button on the "reactor" panel
will remain changed after a status or usage level change to the
station. The value is specified in milliseconds. A
value of 0 (representing "infinite") will leave the color changed
indefinitely (until the user clicks on the station button).
The default value is 30000 (30 seconds).
Parameter: staDetColorChangeMS
This parameter specifies the length of
time that the color for a station detail item will remain changed
after a change in the item's value. The parameter value is
specified in milliseconds. A parameter value of 0
(representing "infinite") will leave the color changed
indefinitely (until the user clicks on the item). The
default value is 30000 (30 seconds).
Parameter: stationChangeColor
This parameter specifies the text color
that a station button on the "reactor" panel will display with
after a status or usage level change to the station. If this
value is "white" then the station button background color will be
changed to "black". See the notes below
for the possible parameter values. The default value is
"white".
Parameter: staDetChangeColor
This parameter specifies the text color
that the value of a station detail item will display with after a
change in the item's value. See the notes
below for the possible parameter values. The default value
is "white".
Parameter: staDetHelpColor
This parameter specifies the text color
that the name of a station detail item will display with if it has
help text linked to it. See the notes
below for the possible parameter values. The default value
is "blue".
Parameter: staDetBkgrndColor
This parameter may be used to specify the
background color for the station detail tabs. See the notes below for the possible parameter
values. If this parameter is not specified or is set to an
empty string then the system-default background color will be
used.
Parameter: groupTabColorFlag
If "true" then the text on a station
group tab will change color when all of its stations are at the
same status level, with the color representing this status
level. If "false" then then text is always colored
black. The default value is "true".

time between updates of the station parameter history plot/list
screens, in milliseconds. The default value is 60000 (60
seconds). This parameter may be modified in the program via
the "Settings" window.
Parameter: staParamHistoryAutoUpdateFlag
If "true" station parameter history plot/list
screens auto-update when they are first displayed. The default
value is "true". This parameter may be modified in the
program via the "Settings" window.
Parameter:
showStaParamHistDatapointsFlag
If "true" then graph datapoints will be
shown on station parameter history plots by default. The
default value is "true". This parameter may be modified in
the program via the "Settings" window.
Parameter:
showStaDetailPerfOverTimeFlag
If "true" then the performance-over-time
information for detail items will be shown whenever a new
station-detail page is displayed (same as if the "DPerf" button
was pressed). The default value is "false". This
parameter may be modified in the program via the
"Settings" window.
Parameter: maxHistoryFetchPoints
Sets the maximum number of data points
allowed for a single station-parameter-history fetch from the
server. When more points are requested, multiple
parameter-history fetches are used (to reduce the chance of
communications-timeout errors). The default value is 5000.
Parameter: staParamHistoryGapFactor
Sets the gap-threshold factor for the
station parameter history plots. If the given value is
positive then a line will not be drawn between two data points if
the distance between them is greater than the median distance of
data points times the given value. If the given value is not
greater than zero then lines will be drawn between all data
points. The default value is 10.0.
Parameter: timeGMTFlag
If "true" then date/time values are
displayed using GMT. If "false" then date/time values are
displayed using the local time zone. The default value is
"false". This parameter may be modified in the program via the "Settings" window.

levels is not shown and usage levels are not used in the
app. The default value is "false".
Parameter: firstTabFlag
If "true" then when a displayed tab is
closed the Stations Tab will always be
displayed; if "false" then the most-recently opened tab will be
displayed. The default value is "false".
Parameter: stationSortFlag
This parameter has been
replaced by the stationSortType parameter
and should no longer be used. If 'stationSortType' is not
specified then: If this parameter is "true" then station
buttons will be sorted using the network code first (straight
sort), if "false" then they will be sorted by station name using
any leading network code (e.g. "NN-") as a secondary comparison
value. The default value is "false".
Parameter: stationSortType
Sets the sort type for the station
buttons. See the description of "station
sort
type" selections on the "Stations" settings tab for
available options. The default value is "station code".
Parameter: stationColumnFlag
If "true" then station buttons will be
displayed in columns (instead of rows). The default value is
"false". This parameter may be modified in the program via the "Settings" window.
Parameter: maxNumPerfValues
The maximum number of performance values
per station displayed on the Performance
Tab. This value is checked when there is a change in
performance for the station. If there are more values than this
maximum the oldest values are removed. If this value is "0" then
the Performance Tab is not displayed.
The default value is 256. This parameter may be modified in
the program via the "Settings" window.
Parameter: maxAgePerfValuesDays
The maximum age (in days) of performance
values displayed on the Performance Tab.
This value is checked when there is a change in performance for
the station. All values older than this age are removed. If this
value is "0" then no values are removed because of age. The
default value is 3 days. This parameter may be modified in the
program via the "Settings" window.
Parameter:
maxAgeDetailPerfValuesDays
The maximum age (in days) of
detail-performance-plot values displayed (via the "DPerf" button)
on station-detail tabs. If this value is "0" then no values are
removed because of age. The default value is 2 days. This
parameter may be modified in the program via the
"Settings" window.
Parameter: fetchPerfValuesFlag
Set 'true' to enable the fetching of
historical performance values from the server. If this parameter
is 'true' when the program starts up then historical performance
values will be fetched from the server and displayed on the Performance Tab. The time length of the
fetch into the history is determined by the 'maxAgePerfValuesDays'
setting. (If 'maxAgePerfValuesDays' is zero then a value of 3 days
will be used.) If this parameter is enabled while the program is
running then the fetch will happen at that time. The default value
for this parameter is 'false'. This parameter may be modified in
the program via the "Settings" window.
Parameter: perfToolTipLevel
When station-detail items have a
performance level lower than the level specified by this parameter
then the items will be shown in the mouse-over tool-tips for the
graphs on the Performance Tab.
(A maximum of 10 items may be shown in a tool-tip.) The
default value is "Good".
Parameter: browserCmdPrefix
This command may be used to set the
prefix of the operating system command used to launch a web
browser for displaying URLs. The URL string is placed
directly after this prefix (and before the 'browserCmdSuffix') in
the command string. If this parameter is not given or is set
to an empty string then a command prefix suitable for the detected
operating system will be used (this usually works well).
Parameter: browserCmdSuffix
This command may be used to set the
suffix of the operating system command used to launch a web
browser for displaying URLs. The URL string is placed
directly before this suffix (and after the 'browserCmdPrefix') in
the command string. If this parameter is not given or is set
to an empty string then a command suffix suitable for the detected
operating system will be used (this usually works well).
Parameter: rButtonMinWidth
This parameter specifies the minimum
width (in pixels) allowed for a "station" button on any "reactor"
panel display. If all of the stations buttons on a "reactor"
panel cannot fit using the minimum width and height then vertical
scrolling will be used. The default value is 70 pixels.
Parameter: rButtonMaxWidth
This parameter specifies the maximum
width (in pixels) allowed for a "station" button on any "reactor"
panel display. The default value is 100 pixels.
Parameter: rButtonMinHeight
This parameter specifies the minimum
height (in pixels) allowed for a "station" button on any "reactor"
panel display. If all of the stations buttons on a "reactor"
panel cannot fit using the minimum width and height then vertical
scrolling will be used. The default value is 14 pixels.
Parameter: rButtonMaxHeight
This parameter specifies the maximum
height (in pixels) allowed for a "station" button on any "reactor"

size to be used on "station" buttons on the "reactor" panel
displays. The default value is 11.
Parameter: rButtonSymbolLeftFlag
If "true" the symbols will be displayed
on the left side of a station button on the "reactor" panel.
The default value is "false".
Parameter: rButtonPerfTipFlag
If true then the station-detail items
that have a performance level lower than the level specified by
the 'perfToolTipLevel' parameter will be shown in the mouse-over
tool-tips for the "station" buttons on the "reactor" panel
displays. Note that the Performance Tab must be enabled for
the tool-tips to be shown. The default value is true
(enabled).
Parameter: sButtonSelTimeoutSecs
Specifies the number of seconds after a
"station" button is selected that the button will be automatically
unselected. A value of 0 will specify that station buttons
are never automatically unselected. The default value is 60
seconds.
Parameter: localGeneralHelpString
Specifies the "general" help information
displayed via the 'Help' button. The value may be a URL or a
path/filename. If this parameter is not specified or is set
to an empty string then the value will be fetched from the
server.
Parameter: programSingletonName
Specifies the name of the "program
singleton" file, which is used to ensure that only one instance of
the program is running out of the same directory (when running as
an application). If this parameter is set to an empty string
("") then multiple instances of the program may be run out of the
same directory. When the program is running as an applet,
this parameter is ignored. If the 'userHomeSettingsFlag' parameter
is 'true' and this parameter is not set to an absolute path then
the program-singleton file will be located in a ".snwclient"
directory under the current user's "home" directory. The
default value is "snw_client" (resulting in a "snw_client.psf"
file).
Parameter: commandFileName
Specifies the path and file name (or URL)
of the "command" file used to send commands to the app. The
status of this file is continually polled by the program (rate set
via 'commandFilePollMS'), and when its last-modified timestamp is
updated the file is read and processed. If this parameter is
set to an empty string ("") then a command file is not used.
If the 'userHomeSettingsFlag'
parameter is 'true' and this parameter is not set to an absolute
path then the command file will be located in a ".snwclient"
directory under the current user's "home" directory. The
default value is "snw_client_cmd.ini" (when running as an
application) or "" (when running as an applet). The
following command-file entries are supported:
showStation = "stationName"
showStationTime = snapshotTime
Specifying a 'showStation' value will result in the display of a
detail page for the given station. The 'showStationTime'
value specifies an historical-snapshot time (in seconds after
1/1/1970 GMT) to be associated with the 'showStation' value.
When a value greater than zero is specified and a 'showStation'
value is provided, an historical snapshot of the given station
will be displayed. If 'showStationTime' is not specified or
a value of zero is specified and a 'showStation' value is
provided, a current station-detail page for the given station will
be displayed.
Parameter: commandFilePollMS
This parameter sets the poll rate (in
milliseconds) for the "command" file specified via the
'commandFileName' parameter. If set to zero then the command
file will only be polled once at startup. The default value
is 1000 (polled once per second).
Parameter: progInstanceFavTabsFlag
If "true" then, when an
historical-snapshot instance of the application is launched via a
"Launch Stations Snapshot..." menu item, any tabs marked as
"favorite tabs" will be displayed automatically on the new
instance. The default value is "true".
Parameter: showDebugFlag
If "true" then debug messages are shown
on the console output. The default value is "false".
Parameter: performanceStationRightFlag
If "true" the names will be displayed on
the right side of the performance plot. The default value is
"false".
Parameter: timeRangeQuickSelect
The comma separated list of 1-3 quick
selection values for the time range display for history
list/plot. The default value is "1,3,7".
Parameter: timeRangeUnits
The time range units (hours, minutes,
seconds, days) for the duration when selecting the time range to
display for history list/plot. The default value is "days".
This parameter may be used to directly specify the IOR reference to the GUIAcceptor CORBA object for the NSI server. If this parameter not used (or is an empty string), the IOR reference is fetched using the "GUIAcceptorRefFile" parameter. The default value is an empty string.
Parameter: applicationWidth
This parameter sets the width (in pixels)
of the program's window when running as an application. When
running as an applet, this parameter is ignored. The default
value is 900.
Parameter: applicationHeight
This parameter sets the height (in
pixels) of the program's window when running as an
application. When running as an applet, this parameter is
ignored. The default value is 700.
Parameter: username
This parameter is used when reading the IOR requires authentication. If this
value is an empty string the user will be prompted. The default
value is an empty string.
Parameter: password
This parameter is used if the username
was specified. The default value is an empty string.
Parameter: buttonsTopFlag
If "true" the buttons will be displayed
on the top of the panels that are displayed on the tab. The
default value is "false".
Parameter: staDetStaticInfoRightFlag
If "true" the static information will
always be displayed on the right side of the station
details. The default value is "false".
For parameters that specify a color, the value may be: a color name ("black", "blue", "cyan", "darkGray", "gray", "green", "lightGray", "magenta", "orange", "pink", "red", "white" or "yellow"); three comma-separated numbers (each from 0 to 255) representing the red, green and blue components of the color; or a single number representing the three components (with the red component in bits 16-23, the green component in bits 8-15 and the blue component in bits 0-7).
All stations update delay (ms):
Specifies the sleep delay time between
updates of the "reactor" panel screens, in milliseconds. See also
allStaUpdateSleepMS.
Station detail update delay (ms):
Specifies the sleep delay time between
updates of the station detail screens, in milliseconds. See also staDetUpdateSleepMS.
Station parameter history update delay (ms):
Specifies the sleep delay time between
updates of the station parameter history plot/list screens, in
milliseconds. See also staParamHistoryUpdateTimeMS.
Show popup before restarting connection:
If selected then this program will "pop
up" a dialog to allow the connection to be restarted; otherwise
the connection will automatically be restarted when needed. See
also connectionRestartPopupFlag.
Display times using GMT timezone:
If selected then date/time values are
displayed using GMT; otherwise date/time values are displayed
using the local time zone. See also timeGMTFlag
Enable auto-popup of same-performance subsets:
If selected then this program will "pop
up" subset-of-stations tabs of station buttons when all the
stations involved go to any of the performance levels specified by
the 'autoPopLevels' parameter; otherwise no tabs will be
automatically "popped up". See also autoPopLevelsFlag.
Only auto-pop new same-performance subsets:
If selected then tabs for
subset-of-stations sets with all stations at one of the
'autoPopLevels' performance levels will only "pop up" when the
condition occurs after the client has started; otherwise tabs for
subset-of-stations sets that were already at one of the
'autoPopLevels' performance levels will be "popped up" when the
client starts. See also onlyNewAutoPopFlag.
Save/restore displayed tabs:
If selected then the set of tabs
displayed when the program exits will be saved and then restored
the next time the program is run. See also persistentTabsFlag.
Show main 'Stations' tab:
If selected then the main 'Stations' tab
will be displayed. See also showStationsTabFlag.
Show main 'Performance' tab:
If selected then the main 'Performance'
tab will be displayed. See also showPerformanceTabFlag.
Station sort type:
The sort type for the station buttons.
(See also stationSortType.) The
following selections are available:
Display station buttons in columns (instead of rows):
If selected then station buttons will be
displayed in columns (instead of rows). See also stationColumnFlag.
Display unknown-performance stations:
If selected then stations with unknown
performance will be displayed. See also displayUnknownStationsFlag.
Sort station-detail items in alphabetic order:
If selected then items on the station
detail page are displayed in alphabetically-sorted order (within
their groups). A case-insensitive sort is used. Note that
modifying this setting will not change any currently-displayed
detail pages (they will need to be closed and opened again to
reflect the sorting change). See also alphaSortItemsFlag.
Station parameter history auto-update by default:
If selected then station parameter
history plot/list screens auto-update when they are first
displayed. See also staParamHistoryAutoUpdateFlag.
Show station parameter history datapoints by default:
If selected then graph datapoints will be
shown on station parameter history plots by default. See also showStaParamHistDatapointsFlag.
Show detail items performance over time by default:
If selected then the
performance-over-time information for detail items will be shown
whenever a new station-detail page is displayed (same as if the
"DPerf" button was pressed). See also showStaDetailPerfOverTimeFlag.
Max number of values per station (0=disable):
The maximum number of performance values
per station displayed on the Performance
Tab. See also maxNumPerfValues.
Maximum age of values (days):
The maximum age (in days) of performance
values displayed on the Performance Tab.
See also maxAgePerfValuesDays.
Max. age of station-detail values (days):
The maximum age (in days) of
statil-detail-performance values displayed on the Performance Tab. See also maxAgeDetailPerfValuesDays.
Fetch historical performance values from server:
Selecting this checkbox will enable the
fetching of historical performance values from the server. If
enabled when the program starts up, historical performance values
will be fetched from the server and displayed on the Performance Tab. See also fetchPerfValuesFlag.
On the "Settings" panel, the "Restore Defaults" button will set
all the displayed values to those found in the configuration file
(usually "Client.ini"). Any modifications made to the
displayed parameter values will be committed after the "OK" button
is hit, or ignored if the "Cancel" button is hit.
The User Settings values are saved to make them persistent across executions of the program. When running as an applet, the settings are stored in a browser cookie (which must be enabled in the browser for it to work). The HTML page that launches the applet must be similar to those found under the 'client' subdirectory in the SeisNetWatch distribution (including containing 'mayscript' statements and the 'setCookieValue' function). When running as an application, the settings are saved in a file whose location and name are specified by the userHomeSettingsFlag and settingsFileName parameters (usually "Settings.ini"). The userSettingsFlag parameter may be set to 'false' in the configuration file to disable the saving and loading of User Settings.
Setting the persistentTabsFlag parameter to 'true' in the configuration file (or in the "Settings" panel) will cause the set of tabs displayed when the program exits to be restored the next time the program is run. When running as an applet, there may be a short delay before the latest change to the displayed tabs is saved. (In other words, tab changes made just before the applet is terminated may not be saved. This is due limitations in the browser-cookie implementations.)
When running as an application (and the 'userSettingsFlag' parameter is set to' true'), the size and location of the program's window frame will be saved and restored (via the User Settings file).
