How to detect state changes for server disk partitions ?

How to detect state changes for server disk partitions ?

Hi Team,

I try to monitor disk partition on linux server using CLI & SNMP using "Partition Details of the Device(%)" monitor. But in the two cases, after added monitor Opmanager don't detect state change (mount & umount partitions).
I try rediscovery but it's the same issue.

Does it have a way to do it ?

Thank for your help
