Through the Cleanup Unused Monitoring Instances setting, you control the removal of instrumentation objects that no longer have an associated managed object to monitor. This situation occurs when you remove a setting from a polling group.

For example, when you apply a setting such as Connectivity Polling to a polling group, the IP Manager creates the corresponding instrumentation objects. If you subsequently remove the Connectivity Polling setting from the polling group, the IP Manager responds in one of two ways:

  • With theCleanup Unused Monitoring Instances setting applied to the polling group, the IP Manager removes the corresponding instrumentation objects from memory.

  • With the Cleanup Unused Monitoring Instances setting not applied to the polling group, the IP Manager does not remove the corresponding instrumentation objects from memory.

    By default, the Cleanup Unused Monitoring Instances setting is applied to the following polling groups:

  • Switches

  • Routers

  • Hubs and Bridges

  • Other Systems

    “Default polling groups for the IP Manager” table in the VMware Smart Assurance IP Manager Reference Guide, provides the default polling groups, their target classes and matching criteria, and their default settings.

    Settings affected by the Cleanup Unused Monitoring Instances setting lists the settings that are affected by the Cleanup Unused Monitoring Instances setting.
