So we've been fighting with SNMP and ESXi for quite a while and our primary problem is still not resolved and no amount of Google/Communities searching has really yeilded any results. Our problem is that our Management Server that is receiving the traps does not appear to recognize the OIDs sent by ESXi.
I'm by no means an SNMP guru, but I have configured 3rd party MIBs for several other products with no major issues. However I'm stumped on this one (the lack of documentation from VMware doesn't help). I've been able to extract the MIB files from both VirtualCenter Server and the ESX 3.5 source CD and imported them into our Management Server. However the traps sent by ESXi are still unrecognizable. We suspected our management software as the culprit (because it's generally awful and in dire need of replacement) but after installing another application on another server we also received the same results.
I presume there is a slight difference in the format of the OIDs for ESXi but on visual inspection I haven't been able to locate it. Any insight into this problem would be much appreciated.
Many thanks!
