I have a small update..
I am setting up SIM 7.3 and also IRS for agentless monitoring. I was also trying to work around the firewall issue with ESXi 5.1 and WBEM agents. What I found is this:
- Agentless monitoring enabled on the iLO
- SNMP trap destinations and communities set up in the iLO
- Discoveries through the iLO using SNMP credentials (no host discoveries, only the iLO)
- AMS service/daemon running on the ESXi host
- Gen8 systems only
I now see events forwarded from the ESXi host, through the iLO. I did NOT add WBEM credentials or set up WBEM subscriptions, so I know no WBEM events are being forwarded. What I end up seeing in the server record is a "major" event status for test events (in both the server events and the iLO events page) and also "critical" events for any actual alert. I have a few hosts that had issues and after discovery, I am seeing HBA events and one server has a failed disk drive. If i look at the server's health status, I only see SNMP as a protocol, and the failing component.
Now, I do have the full agent bundles on the servers, i have not tested this with AMS ONLY. However, this "fixes" the issue for me, for now. I am going to see about removing the complete bundles from Update Manager for new ESXi builds to see if this is still working this way. We don't want to continue using the complete bundles anyhow since it's redudant. I just want AMS + the utilities.
I hope this helps.. if anyone can verify that this works with just AMS, that would be great. I'll try to test on my own as well.
I have also not tested this on SIM 7.2.2, but I assume it works the same way since it avoids WBEM traps completely.
