Hello All,
After upgrading a OEM to 13c, I started to receive notifications for event “sizeOfOSAuditFiles:FILE_SIZE“.
This is a new event implemented on OEM DB Plugin 12.1.0.7.0 under “Operating System Audit Records” metric group. Upgrading DB Plugin was part of OEM Upgrade change once we had some old versioned.
This event is only a notification related to file size for space management ends. The default thresholds are 10MB (warning) and 20MB (critical), which in most of times it’s a pretty low value.
This is specifically related to location under parameter audit_file_dest if you want to check.
Between options to reduce the noise are disable this metric or increase thresholds accordingly, which was what I did.
At this moment, I just increased thresholds to 500MB/2048MB, which I consider good values for the environment.
Some reference about can be found at:
– Enterprise Manager Oracle Database Plug-in Metric Reference Manual (Plug-in Release 12.1.0.7) – Database Instance – Operating System Audit Records
– EM 12c, EM 13c: Troubleshooting Database Metrics in Enterprise Manager 12c and 13c Cloud Control (Doc ID 2032156.1)
Hope it helps,
Cheers!
Thanks much..
