How do I set up Manual Threshold Alarm?

You can create manual threshold alarms using trend reports. The steps involved are:

ADDING A REPORT
- select the objects you want to monitor.
- go to the snmpc "Trend Reports" selection tree (printer tab)
- use the "Insert/Trend Report" menu to add a new report
- select one of the include tables from the pulldown, or use the ">>" button to select a different mib table
- select a polling interval. For thresholds that check for an average over 10 minutes, select 10 minute poll interval.

EDITING THE INSTANCES:
- use the Instance button to view the table instances for the selected objects
- select one or more instances from the table for which you would like to set threshold alarms
- Press the Add button. The selected instances will be added to the appropriate object subtrees on the left
- if you only want to save/check the selected instances, then you can select the <All Instances> items and press Exclude
- if you want to set the same threshold for all instances then you don't need to add the instances but just continue onto the next step and edit the <All Instances> item

FOR EACH INSTANCE ADDED (still in Instance dialog):
- select the instance in the left tree
- press the Edit button
- select the variable you want to monitor
- enter a threshold expression in the Threshold edit box. This can be a series of comma separated expressions such as "<10,>20"
- press OK at the Edit dialog
- repeat Edit dialog for each other instance
- press OK at the Instances dialog
- press OK at the Trend Report dialog

You will now get threshold alarms for this report. The alarm will be "alarmManualThresholdTrigger". To set custom actions, do the following:

- go to the snmpc Event Actions selection tree (blue bell tab).
- open the SnmpcNT-thresholdAlarm subtree and then the alarmManualThresholdTrigger subtree
- to set global actions, right-click the Default filter and use the properties menu. To set actions for a specific node/group, use the right-click Insert Filter menu
- to match specific nodes, use the Match tab
- to set actions, use the Actions tab
You can close this window when you are done.
