I would have thought that there would be a built in symptom for this but there isn't (only for real snapshots which would usually work for this issue but I know of times when consolidation is needed but there are actually no snapshots.)
What about using the Virtual Machine Metric: "Waste % > 0" I do not know if this will work but worth a try?
Because it's not a vSphere alarm (Instead a "Summary: Configuration issue") I can kind of see why this didn't make it into vROps - but it should be!
I would be interested to see if there is actually a snapshot file associated with this VM, I suspect there is nothing in snapshot manager, but do you see any on the VM folder on the datastore?
Graham, thank you for your reply.
You are correct; we see this problem when consolidation is needed but no snapshots are actually present. This happens occasionally after nightly backups (CommVault). Right now; the only report method we have is a storage administrator notifying us (server administrators) that a nightly backup failed; a report is generated by the backup software and then we investigate vCenter to remediate each individual server.
I will try your recommendation, Virtual Machine Metric: "Waste % > 0", the next time we have a machine that requires the consolidation. There aren't any currently in our environment.
Did you have success with the Waste % > 0 symptom? When I try to create this symptom definition I receive the error, that I cannot create this definition, because badge syptoms are managed by the system.
Is there any possibilty in vROPS that i can set an alert based on the disk consolidation events in vCenter (similar to this description - vROPS – How to get an alert and email notification when a VM is down | VMignite.com ):
In vROPS I can see for example any Virtual Machine configuration change event. But I was no able to figure out how I can list the disk consolidation events.
I did not have success with the "Waste % > 0" symptom. I ended up using LogInsight to track the "Disk Consolidation Needed" messages.
