Create gauge monitors

Before you begin

A gauge monitor periodically checks the value of an integer or floating-point attribute and generates a trap if the value exceeds a threshold.

To create a gauge monitor:

If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the Administration Console, expand Diagnostics > SNMP Agent > Monitors and select Gauge Monitors.
On the SNMP Gauge Monitors page, click New.
Note: Once you create a gauge monitor, you cannot rename it. Instead, you must delete it and create another one that uses the new name.
On the Create a new Gauge Monitor page, enter a name for the monitor.
In Monitored MBean Type, select an MBean type and click Next.
For more information, refer to Determine MBean types and attribute names.
In Monitored Attribute Name, select an attribute and click Finish.
On the SNMP Gauge Monitors page, click the new monitor name.
To monitor only a specific MBean instance, enter the instance name in Monitored MBean Name. See Determine MBean instance names.
If you do not enter an instance name, the monitor observes all MBean instances of the type that you specified in Step 4.
In the Polling Interval field, enter the frequency in seconds at which you want WebLogic Server to check the attribute's value.
For testing purposes, enter a small value, such as 10.
To send a trap when the observed attribute value is equal to or greater than a specific value, enter the value in the High Threshold field.
To send a trap when the observed attribute value is equal to or less than a specific value, enter the value in the Low Threshold field.
Click Save.

After you finish

Target gauge monitors

You do not need to restart the Administration Server after you create and initially configure a monitor. However, if you change a monitor after you create it, you must restart the Administration Server.
