Create string monitors

Before you begin


A string monitor periodically checks the value of a String attribute and generates a notification if the value is equal to or different from another specified string.

To configure a string monitor:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the Administration Console, under Domain Structure, expand Diagnostics and select SNMP.
  3. On the Summary of SNMP Agents page, in the Server SNMP Agents table, click the name of an SNMP agent.
  4. On the SNMP Agent: Configuration: General page, click the String Monitors sub-tab.
  5. On the SNMP String 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.

  6. On the Create a New SNMP String Monitor page, in the Name field, enter a name for the string monitor.
  7. In the Monitored MBean Type list, select an MBean type and click Next.

    For a description of WebLogic Server MBean types and attributes, see the MBean Reference for Oracle WebLogic Server.

  8. In Monitored Attribute Name, select an MBean attribute and click Next.
  9. In String to Compare field, enter a string that the monitor will compare to the attribute value and click Finish.
  10. On the SNMP String Monitors page, click the new string monitor name.
  11. On the SNMP String Monitors: General page, specify whether you want the monitor to send a notification when the observed attribute value differs from or matches the string:
    • To send a notification when the observed attribute value differs, check the Notify Differ box. For example, if you want to be notified when a server's life cycle state is anything other than Running, enter Running in the String to Compare field and check the Notify Differ check box.
    • To send a notification when the observed attribute value matches, check the Notify Match box.
  12. To monitor only a specific MBean instance, in the Monitored MBean Name list select an MBean instance. See Specify MBean instance names.

    If you do not select an instance name, the monitor observes all MBean instances of the type that you specified in Step 6.

  13. Click Save.
  14. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).

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 string monitors.
