|INFOPORT||The portnumber to contact for general information. Opening a connection to this port should trigger a script that dumps the contents of /proc/net/dev (with an additional line consisting of exactly one #). See the install instructions for an example of such a script|
|ALIGNMENT||Specifies whether the graphs should be aligned in X- or in Y-direction.
If you specify "Y" the applet will use vertical alignment; every other value will make the applet use horizontal alignment.
If you don't specify this parameter at all, the applet will use vertical alignment.
|DRAW_CLIENT_BORDER||Specifies whether a border around the client area (where the graphs
are drawn) should be displayed
0 or "false" to not draw a border
1 or "true" to draw a border
Specifies whether a border around the component should be displayed
0 or "false" to not draw a border
1 or "true" to draw a border
|INSETS||Specifies the number of pixels between the outer border of the component and the area that will be used to draw strings/lines etc.|
<PARAM NAME=xxxx_COLOR Value="RRGGBB"> where RR is the 2 digit hex-code for the red component of the color GG is the 2 digit hex-code for the green component of the color BB is the 2 digit hex-code for blue red component of the colorFor example: 00FF00 for pure red or C8C8C8 for gray
|CONTROL_BACKGROUND_COLOR||The color of the title-bar and status bar (default C8C8C8)|
|CONTROL_FOREGROUND_COLOR||The color of the text in the title- and status-bar (default 000000)|
|DATA_BACKGROUND_TRYING_COLOR||The color of the section of the screen, where the data from the device is displayed
(default FFFF00) (when the device is trying to go online)
Currently, only relevant for ISDN-Devices
|DATA_BACKGROUND_OFFLINE_COLOR||The color of the section of the screen, where the data from the device is displayed
(default C8C8C8) (when the device is offline)
Currently, only relevant for ISDN-Devices
|DATA_BACKGROUND_COLOR||The color of the section of the screen, where the data from the device is displayed (default 144014)|
|DATA_FOREGROUND_COLOR1||First color of the data (default 00FF00)|
|DATA_FOREGROUND_COLOR2||Second color of the data (default 00FFFF) (only used in line-view)|
|GRID_COLOR||Color of the grid (default 006000)|
|BAR_BACKGROUND_COLOR||The background-color of the bar in bar-view (default 288028)|
|CPU_SYSTEM_COLOR||Color for system (=Kernel) CPU-usage (default FF0000)|
|CPU_USER_COLOR||Color for user-space CPU-usage (default 0000FF)|
|CPU_NICE_COLOR||Color for nice CPU-usage (default 0000FF)|
|CPU_IDLE_COLOR||Color for idle CPU-usage (default CONTROL_BACKGROUND_COLOR)|
|DEVx_NAME||This parameter specifies the name of the device (eth0 or so). This parameter must be the first in the list.|
|DEVx_LABEL||This parameter specifies the name that should be displayed in the applet. If no label is specified, the device-name is shown.|
|DEVx_DRAW_LEGEND||Specifies (any value !=0 will do) that a "legend" should be drawn in line view. This means that there will be two labels ("In" and "Out") in the upper right corner of the window, each in the color the line for the corresponding value is painted.|
|DEVx_DRAW_TITLE||Specifies (any value !=0 and !="false" will do) that a title bar with the name (or, if specified, the label) of the device should be drawn|
|DEVx_DRAW_STATUS||Specifies (any value !=0 and !="false" will do) that a status bar with the current in/out/maximum values should be drawn|
|DEVx_GRID_INTERVAL||Specifies how many bytes should be between grid-lines.|
|DEVx_GRID_LINECOUNT||Specifies how many gridlines should be painted. This was introduced
because for devices with high throughput it is more practical to
define that 10 lines should be drawn rather than that the interval
is 131072 (for a 10MBit device).
You should only give a value for either DEVx_GRID_INTERVAL or DEVx_GRID_LINECOUNT. If you specify a value for both, the value for DEVx_GRID_LINECOUNT has higher priority.
If you don't specify a value for either, no grid is drawn.
|DEVx_SHOW_CPU_USAGE||If set to a value different from 0, cpu-usage of the router will be displayed (only works with the C server side program, not with the script).
This will be a bar above the title of the graph (so if you set DEVx_DRAW_TITLE to not draw a title, you will also not get cpu-usage).
See the colors section for information on how to specify the colors to be used.
Note: if the parameter INSETS is specified to something less than 4, no cpu-usage will be drawn!
|DEVx_MAX||Specifies the maximum throughput this device can have, in bytes per
second. So for a 100 MBit network card, specify 13107200, for 10MBit
1310720, for an ISDN-device 8192 and so on (MBits/8*1024*1024). This
is used for the scaling in bar, line and histogram mode.
WARNING: if your device supports (and uses) full duplex, the maximum throughput parameter should be twice the theoretical throughput when using histogram mode (since here in and out are added).
This parameter is only evaluated for bar, line and histogram view.
For line and histogram view, you can also specify "auto" and "auto_accumulate" to enable autoscaling. "auto_accumulate" scales using the maximum value since the applet was started; "auto" will use the largest value that's currently being displayed.
|Specifies the number of bytes that should be subtracted from the throughput before displaying the data. This way you can filter out a constant load on the device that you don't want to see.|
|DEVx_MODE||Specifies how the data shall be displayed. Possible values are: histogram, doublehistogram, line, bar or numeric|
|DEVx_DONT_NORMALIZE||If set to a value different from 0, the values will not be normalised to values per second|
|DEVx_ABSOLUTE||If set to a value different from 0, the values will be displayed as is, and not the change from the previous value. This only makes sense when you're monitoring other data, like CPU-Temperature, number of processes or something like that.|
|DEVx_PERCENT||This will cause the input value to be converted to a percentage (in + out = 100 %)
In Line-graph, only one line will be drawn, in all others the out-value will always be considered 0
Great for displaying CPU-usage as a graph, where in would be System+User+Nice and out would be idle.
|DEVx_IN_CAPTION||Specifies the string to be displayed in the status bar and legend, in front of the in-values. Default: "In"|
|DEVx_OUT_CAPTION||Specifies the string to be displayed in the status bar and legend, in front of the out-values. Default: "Out"|
|DEVx_DRAW_TICKS||Specifies that a grid along the X-axis should be drawn|
|DEVx_TICK_INTERVAL||Specifies the interval (in pixels) between each "tick" along the x-axis (default 10)|
|caption: The string to be displayed in the menu|
|GET dir||dir is the part behind the hostname in the URL, like /cgi-bin/goOnline.sh
This tells the program to fetch an html-document from the specified position on the current server (other servers cannot be contacted due to the Java-Sandbox)
The protocol-part for this URL is always assumed to be "http://"
|OPEN portnumber||Opens a connection to the specified port (and waits until this connection is closed again)|
The action is now being run in a separate thread - so you can also specify an action that will take a long time to complete (like, triggering sendmail send mails in the queue, or fetchmail to fetch emails). As of version 0.8 the applet will no longer be blocked until the action is completed.
Components for ISDN-devices will be painted in different colors, depending on the status. By default, this is green for an online device, gray for a device that's offline, and yellow while the device is trying to connect. See the color section for details on how to customize these colors.
Together with the actions that can be defined, this makes for a rather decent "dial manager". Of course, it works for modems as well, but without detection whether the line is up or down.
If you have more than one cpu, the first two are displayed as device "cpu0" (the first cpu will be presented as "incoming traffic", the second as "outgoing traffic"). The next two as device "cpu1" and so on. This has been tested on a system with 4 cpus and it works fine. If you want to use it on a system with more cpus, you'll have to change the "MAX_CPUS" define in src/server/lrpStat.h and recompile. I don't have access to a system with more than 4 CPUs, so I can't test it myself, but it should work.

java LrpStatApplication [-v] [-vertical] [-width value] [-height value] [-configfile htmlFilename] -hostname routername [paramName paramValue] [paramName paramValue] ...Command-line parameters:
|-v||Prints verbose messages (should be turned on for troubleshooting)|
|-vertical||Specifies that the controls for monitoring several hosts are aligned vertically (default is horizontal). This does not interfere with the "ALIGNMENT" Parameter in the html-file|
|-width||The width of the window (default 640)|
|-height||The height of the window (default 480)|
|-configfile||The name of the html-file that could also be used to start the applet (must be a local file)|
The name of the router you want to monitor
|paramName||Any number of parameters. This is equivalent to specifying a config file with the parameters defined there|
Note: that whole block of
-hostname xxx -configfile yyy applet-parameters may
be repeated as often as desired (obviously, with different values). This way,
you can display several connections to different computers at the same time.
The controls will be displayed with horizontal alignment (one next to the other).
If the parameter name or value contains spaces, enclose the name/value in parentheses. For example:
DEV0_LABEL "Internal interface"
You should not specify parameters on the command-line that are also specified in the config-file. If you do, which parameter takes effect depends on where the parameter is specified in the command line (before or after the -configfile parameter).
The easy way to get the application running is to set everything up the way
you want in Netmon.html (but not upload to the web-server) and start the
java LrpStatApplication -hostname host -configfile Netmon.html
If you want to "swallow" the application into the Gnome-panel, you should specify that the application doesn't paint a legend, title, status bar or borders - that way, the available space will be used effectively.
