Sample Self Monitor Table Entry
This section provides an example of an entry in the Self Monitor table that instructs the SystemEDGE agent to monitor the 1-minute load average on the target system (table separated for viewability):

This entry provides the following information:
- This is the 21st row in the table.
- Its purpose is to monitor the system's 1-minute load average.
- Every 60 seconds, the agent checks the absolute value of the loadAvg1Min MIB variable (whose current value is 320) to see if it is greater than 300 (the specified threshold value). If it is, the agent changes the current state to warning (defined by the Severity value) and sends a state change trap if this monitor represents the worst state for the corresponding managed object in the Aggregate State table.
- With each poll, the agent updates the CurrVal column with the value it has just retrieved, records the time in the LastCall column, and updates the MinValue and MaxValue columns if appropriate (that is, if the value just polled is the lowest or highest value observed thus far).
- The RowStatus column shows that this entry is active. In this example, the action is null, so no command will be run when the trap is sent.
- The Flags column is set to zero, which indicates the default Self Monitor table behavior.
- The class, instance, and attribute values establish this self monitor entry as a part of the managed object with these values in the Aggregate State table. You can define other self monitor entries with these same values to monitor for different severities, or you can aggregate this entry with other related objects.
