A counter monitor periodically checks the value of an integer attribute and generates a notification when the value exceeds a threshold. You can also configure a counter monitor to increase the threshold by an offset value after it sends a notification.
Note: Once you create a counter monitor, you cannot rename it. Instead, you must delete it and create another one that uses the new name.
For a description of WebLogic Server MBean types and attributes, see the MBean Reference for Oracle WebLogic Server.
If you do not select an instance name, the monitor observes all MBean instances of the type that you specified in Step 6.
Each time the observed attribute equals or exceeds the new threshold, the threshold is increased by the offset value. For example, if you set Threshold to 1000 and Offset to 2000, when the observed attribute exceeds 1000, the Counter Monitor sends a notification and increases the threshold to 3000. When the observed attribute exceeds 3000, the Counter Monitor sends a notification and increases the threshold again to 5000.
To specify a maximum value for the threshold, enter a value in the Modulus field. When the threshold reaches the value specified by the modulus, the threshold is returned to its original value before any offsets were applied. For example, if the original Threshold is set to 1000 and the Modulus is set to 5000, when the Threshold exceeds 5000, the monitor sends a notification and resets the Threshold to 1000.
For more information about these fields, see Configuration Options.
After you finish
If you plan to target the SNMP agent that contains this monitor to the Administration Server, specify which servers in the domain you want this monitor to observe. See Target counter monitors.
