Book Title
Problem: An RMON rule is defined to monitor a counter variable, and to cause an alarm when the
counter exceeds a certain value. The counter has exceeded the threshold value but no alarm has
occurred.
There are several things to check:
Make sure the RMON rule and the alarm definition are set up correctly
●
If the value of the counter was already above the threshold value when you set up the RMON rule,
●
and you have the Sample Type set to Absolute, no alarm will ever be generated. This because the
value must fall below the Falling Threshold value before the before another Rising Threshold trap
will be sent, and this will never occur. You should consider using the Delta Sample Type instead.
Problem: When creating an RMON rule in the RMON Rule Configuration window, the MIB variable
I want to use is missing from the list of variables displayed when I click "Lookup..."
The MIB Variable list displays only the MIBs shipped with the Ridgeline software. In addition, within
those MIBs the variable list will not display variables that are indexed by an index other than (or in
addition to) ifIndex. You can still use variables that do not appear in the Lookup... list, but you must
type the complete OID into the MIB Variable field, in numeric notation. If the variable is a table
variable, you will need to append the specific index and apply the variable to each target device, one at
a time.
Problem: A program specified as an action for an alarm (in the Run Program field) does not get
executed. It includes output to the desktop among its functions.
You must specifically tell it to allow output to the desktop. To do this you must stop and restart the
Ridgeline server, as follows:
1 In the Windows Services window, select Ridgeline 3.0 Server and click Stop. (To find the Services
window, from the Start menu select Settings, then Control Panel, the double-click the Services icon).
2 When the Ridgeline 3.0 Server service has be stopped, select it again and click Startup.... This
displays a pop-up window where you can specify start-up options.
3 In the lower part of the window, in the Log On As: area, click the box labeled Allow Service to
Interact with Desktop. Then click OK.
After the Ridgeline server restarts, the program you have specified as an alarm action should execute
correctly.
To specify a batch file that does output to the desktop, you must specify the ".bat" file within a DOS
"cmd" command, as follows:
cmd /c start < file.bat
where < > is the batch file you want to run.
file.bat
Problem: Email alarm actions generate too much text for a text pager.
You can use the "Short email to:" option to send an abbreviated message appropriate for a text pager or
cell phone. The short email provides only very basic alarm information. See
on using the email options as an alarm action.
