CRS alert from Oracle Enterprise manager

We have agent installed on our RAC DB. Oracle Enterprise Manager grid control is monitoring CRS on it
The alert is like :

Cluseterware has problems on all hosts of this cluster. Verifying CRS integrity ,,Checking CRS integrity...,,ERROR: ,PRVF-4037 : CRS is not installed on any of the nodes,Verification cannot proceed,,,CRS integrity check failed,,Verification of CRS integrity was unsuccessful on all the specified nodes. ,NODE_STATUS:
We can use ocrcheck of CRS Home to verify it manually. The manual test is fine.
Then we suspect something affecting agent to run the integrity script.
It turns out we change oraInventory of  /etc/oraInst.loc. It confused agent, we rollback the changes, the alert is gone. Good to know agent monitoring is tied with oraInventory.
