Ever run into NOT monitored servers?
Unsure your experience, but recently, I’ve run across multiple occurrences where servers show up as ‘not monitored. As a result, I’ve found three distinct sets of issues that might cause ‘not monitored’ status –
1) Orphaned Agent blog
This scenario usually entails deleting server from Managed Agents view in Administration tab, where alerts or other details may still exist. The procedure leverages Holman’s orphaned agent blog (tried and true) post from years back to aid cleanup.
2) Do you have packs or connectors extending classes?
3) Rebuilding a server with the same name is a common server occurrence
Related to 1, Holman’s orphaned agent blog to be used to cleanup.
First, let’s test in the Lab. Second, let’s talk about the express lane ‘easy button’. Begin by deleting the Windows Computer orphaned object GUID. Process the Windows Computer object (bottom), followed by the top two (2) are HealthService, and HealthServiceWatcher object properties (see three items highlighted).
Second piece, marking the Windows Computer GUID for deletion (IsDeleted=1) cleans up nearly ALL properties. See the progress below, how this slight change makes short order of orphaned properties for ‘server’.
Third HealthService & SCVMM objects require manual deletion per GUID.
Note first screenshot shows health service properties marked ‘IsDeleted’ = 1 after manually processing each GUID.
Fourth, screenshot shows there the HealthServiceWatcher property is marked for deletion (IsDeleted=1)
If you have SCVMM, you will need to repeat for each of the SCVMM properties to clear out the orphans in the DB.
Why – the issue:
Typically, when servers are reimaged, i.e. NOT deleted from SCOM, there are two+ healthservice, HealthServiceWatcher, Windows Computer properties created for each image of example server. Additional properties may show duplicated for any class discoveries that are common to the old and new image.
NOTE: Deleting the current agent may clean up objects for that instance of the discovered server, but NOT the old server image.
