SNMP Tricks: Useful OIDS for ESXi Servers

[johncwelch]

If you're running ESXI servers, while you can't get a LOT of information directly from ESXi via SNMP, there's still one set of OIDs that is of use, namely the .iso.org.dod.internet.private.enterprises.vmware group or .1.3.6.1.4.1.6876

With the exception of the first five, which give you info about the server itself:

.iso.org.dod.internet.private.enterprises.vmware.vmwSystem.vmwProdName.0 = STRING: VMware ESXi
.iso.org.dod.internet.private.enterprises.vmware.vmwSystem.vmwProdVersion.0 = STRING: 5.5.0
.iso.org.dod.internet.private.enterprises.vmware.vmwSystem.vmwProdBuild.0 = STRING: 1331820
.iso.org.dod.internet.private.enterprises.vmware.vmwSystem.vmwProdUpdate.0 = STRING: 0
.iso.org.dod.internet.private.enterprises.vmware.vmwSystem.vmwProdPatch.0 = STRING: 0

The rest of that OID group are set up in a series of tables. For example, the .iso.org.dod.internet.private.enterprises.vmware.vmwVirtMachines.vmwVmTable, (.1.3.6.1.4.1.6876.2.1) which gives you basic info on each vm you're running on that server, such as display name, config file path, Guest OS info, Mem size, state, guest OS state, CPUs and the VM UUID:

.1.3.6.1.4.1.6876.2.1.1.2.4 = STRING: windows7vm
.1.3.6.1.4.1.6876.2.1.1.2.5 = STRING: IT Wiki Server

.1.3.6.1.4.1.6876.2.1.1.5.6 = INTEGER: 2048 megabytes
.1.3.6.1.4.1.6876.2.1.1.5.7 = INTEGER: 1024 megabytes
.1.3.6.1.4.1.6876.2.1.1.5.11 = INTEGER: 4096 megabytes

The .iso.org.dod.internet.private.enterprises.vmware.vmwVirtMachines.vmwVmNetTable (.1.3.6.1.4.1.6876.2.4) gives you the MAC addresses for the VMs:

.1.3.6.1.4.1.6876.2.4.1.7.4.4 = STRING: 0:c:29:c6:c5:18
.1.3.6.1.4.1.6876.2.4.1.7.5.4 = STRING: 0:c:29:f9:70:cf
.1.3.6.1.4.1.6876.2.4.1.7.6.4 = STRING: 0:c:29:a2:5d:f4
.1.3.6.1.4.1.6876.2.4.1.7.7.4 = STRING: 0:c:29:99:40:3b
.1.3.6.1.4.1.6876.2.4.1.7.11.4 = STRING: 0:c:29:ae:21:71

so on and so forth.

you can get the same info from various fat/web clients, but this can be handy if you're building your on management console.

Thank you @johncwelch][/url. I actually set up an ESXi server last week and have been having a lot of fun with it so this is good info.

[johncwelch]

Excellent! If you haven't yet, download the VMware Fusion 2014 July Technical Preview. It's got some basic ESXi features, like a MUCH better console and drag and drop to copy VMs from Fusion -> ESXi

Dear John,

Can you advise how to get System OID on esxi 4 & 5 ,

THanks,
