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 isti.com.
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 3-5
character
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.
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

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: 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 file 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. Note that if an absolute
pathname is specified in the 'settingsFileName' parameter then this
parameter will have no effect. The default value is 'false' (put
User Settings file in program installation directory). This
parameter setting also affects the '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. The 'userHomeSettingsFlag' may affect the location of the
User Settings 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").
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: 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 before 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
This parameter specifies the sleep delay time
between updates of the "reactor" panel screens, in milliseconds.
The default value is 5000 (5 seconds). This parameter may be
modified
in the program via the "Settings" window.
Parameter: staDetUpdateSleepMS
This parameter specifies the sleep delay 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".
Parameter: staDetTabColorFlag
If "true" then the text on a Station
Detail Tab will track the status
level of the station. If "false" then
then
text is always colored black. The default value is "true".

If "true" then agent information button icons
will not be shown preceding items on the station detail displays.
The default value is "false".
Parameter: originalOrderFlag
If "true" then items on the station detail
page are displayed in the original order that they are received.
If "false" then the items are grouped by type. The default value
is "false".
Parameter: alphaSortItemsFlag
If "true" then items on the station detail
page are displayed in alphabetically-sorted order (within their
groups). A case-insensitive sort is used. The default value
is "false".
Parameter: staParamHistoryUpdateTimeMS
This parameter specifies the amount of 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: 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.
Parameter: noUsageKeyFlag
If "true" then the symbol key for usage 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" panel
display.
The default value is 30 pixels.
Parameter: rButtonFontSize
This parameter specifies the text font size
to be used on "station" buttons on the "reactor" panel displays.
The default value is 11.
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: 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 before 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: showDebugFlag
If "true" then debug messages are shown on
the console output. The default value is "false".
Parameter: GUIAcceptorIOR
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
860.
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.
Notes: Within string
parameters (surrounded by double
quotes),
any "special" characters should be "quoted" by preceding them with a
backslash
('\'). "Special" characters include the double quote and the
backslash.
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.
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.
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).
