SNMP working on some Dell servers but not all

I’m using the Dell OID recipes provided on this site: SNMP Recipes

SNMP is working on some of our Dell servers, but we just added a couple of new clients and I can’t get it working for the life of me. The bare-metal servers are acting as both the hostname and the monitoring agent for SNMP. The asset monitors all say ‘Timeout’.

Here are the steps I’ve tried so far:

  • Enabled the SNMP Windows feature
  • Opened the ports in the Windows firewall.
  • Changed the SNMP service properties to the name public and to accept packets from any host.
  • Installed Dell OMSA
  • Opened a ticket with Dell support to confirm there’s nothing else to configure on the server.
  • Enabled all SNMP settings in iDrac
  • Tried the hostname and IP address in Syncro.
  • Tried removing several SNMP monitors to lower the count

Any ideas on what to try next?

That’s a pretty extensive list, oddly sometimes switching out the monitoring agent to something else, saving, then switching it back in resolves some issues.

Since you’ve already done quite a bit, if you want to send some screenshots to and let us know which devices you’re looking at we can check it out.
