We are experiencing delays in alerting from the CDM probe, specifically for disk errors. The alerts are set for 2 samples at 7 min intervals but it takes over 25 min for the alert to generate.
cdm disk alarm shows up when the probe is restarted but not at the time interval it is being monitored based on the configuration, hence it seemed like the alarms were delayed.
We made this change:
*cdm disk timeout is now set to 15* (from default of 5).
Existing Disk Properties
---------------------
Interval 7 mins
samples 2
Ignoring 2 file systems
17 filesystems being monitored.
We also tested a 2nd cdm probe instance after increasing the timeout to 15, and the cdm disk alarm showed up 7 minutes later.
The same alarms showed up in IM as well as OC.
Issue resolved.
