CheckMK Docker SNMP - Notification Issue

shandy4473 · April 4, 2026, 3:43am

Good Day Everyone,

I have a CheckMK Docker implementation using SNMP to monitor 168 Dell physical hosts thru each IDRAC on each host. I have created two notification rules as shown in the embedded photos. The issue that I am not seeing email alerts sent out except for one host - VR3ESXHOSTP06-IDRAC. I have two rules created to:

Wait 5 mins for sending out an alert in critical state
Send out an alert only once a day.

Not sure why I am not seeing alerts sent out for the critical alerts shown in red. Can anyone assist in suggesting why I am seeing this behavior?

I am running CheckMK Raw (Community) 2.4.0p24 Docker

Thanks

Steve

Why not use the Redfish agent with the Dell iDRACs?

Great Idea Mr Sander. I have started using Redfish. What are your suggestions for retry and timeout settings within the “Redfish Compatible Management Controller”

Thanks

Steve
