Splunk support for SNMP v3

[leonheart78]

Hi,

I would like to know if Splunk officially support SNMP v3? I have found an app named SNMP Modular Input, but it is not developed by Splunk.

Thank you.

Unfortunately no, Splunk enterprise doesn't come with SNMP support out-of-the box. As you suggested, this is available as a modular input on the apps store: http://apps.splunk.com/app/1537/.

The above app looks like it's written by a Splunk employee (has an @splunk.com email address), however, I doubt it would be officially supported in the sense that you could lodge a support ticket for it (they do have premium apps that fall in to this category). It should be absolutely fine to use. The source code is available on github if you'd like to have a look over it first: https://github.com/damiendallimore/SplunkModularInputsPythonFramework/tree/master/implementations/sn...

The readme for this app indicates that it supports SNMP v3, but you'll need to drop a copy of the pycrypto library in to the app's bin directory before it will work.

If you run in to any trouble getting it set up, by all means say so and I'm sure the community can help to get you up and running.

Today I just happened to stumble across this which I thought may also be of interest:
http://docs.splunk.com/Documentation/Splunk/latest/Data/SendSNMPeventstoSplunk

Looks like Splunk suggest that you could run an snmp service (not Splunk specific) and configure it to log its results to file. Splunk can then pull in these logs just as it would with any other log type.

It may be a better option if you're concerned about using an (officially) unsupported add-on.
