You can specify how the probe manages subscriptions to Microsoft SCOM 2012 using the CleanUpOnShutdown and CleanStart properties.
Clean up on shutdown
You can use the CleanUpOnShutdown property to specify whether or not the probe de-registers its connector and unsubscribes from Microsoft SCOM 2012 at the end of a session. The probe can only clean up connectors and subscriptions that have been fully registered during a session. If, for example, the probe shuts down before the connector or subscription is fully established, the probe cannot clean up that connector or subscription on shut down.
If you specify a value of true for this property, the probe will remove the connector and clean up the current subscription. When the probe reconnects, it will recreate the connector and subscribe only to new alerts. If you specify a value of false for this property, the probe will maintain the connector and subscription between sessions. The default is false.
If you use the Ctrl+C command in a Windows console to shut down the probe, it can take up to one minute for the probe to perform the clean up process. During this time, the progress of the clean up is not reported in the console. It is important to allow enough time for the probe to perform the clean up before trying to shut it down a second time. Using Ctrl+C a second time, while clean up is in progress, might result in an incomplete clean up.
If you deploy two instances of the probe in a peer-to-peer failover configuration, the clean up on shut down function is only available to the master probe and not to the slave probe.
You can use the CleanStart property to specify whether or not the probe processes alerts from a previous subscription when it starts up. If you specify a value of true for this property, the probe ignores any alerts created in a previous subscription. The probe will only process alerts created since the start of the current session.
If you specify a value of false for this property, the probe will process any alerts that were created since the previous session. The default is false.
