Our ISO27001 auditors have mentioned a point of failure being the server running OME. If the service goes down we dont get alerts. (SNMP alert ->OME-> email to admin team.)
Is there a mechanism for OME to send me a daily email. Ideally it would contain something useful (eg overview of systems health), but I suppose anything that implied OME was still up would be good enough.
Thinking about it I could script a "test" SNMP alert on some server to go off each day, it will look messy but is does the job. If I was clever I could edit a MIB to get a better email subject.
I can't think of a heartbeat mechanism that is built-in. I just tested and it does respond to ICMP requests, so you could set up a simple ICMP heartbeat. I suspect there are several simplistic monitoring applications that are readily available for monitoring availability with ICMP. You should also be able to use SNMP to monitor heartbeat.
Here is a thread on Spiceworks where several suggestions were made:
I just noticed this was OpenManage Essentials and not Enterprise. ICMP would probably not be a good indicator that the OME application is running properly since it would just be testing the host OS network response.
You could use OME CLI to run a command like Get-DiscoveryStatus -Range rangename
A script run on a schedule with a task scheduler service could return an up or down based on expected return values.
