Polling should be sending out messages? Searched in the Splunkd log (index=_internal sourcetype=splunkd snmp) and did find some messages. I've set up trap notifications on the server's I'm monitoring and assuming those are the SNMP messages being received. Installed Wireshark, another great tool, and I do see SNMP data coming into the Splunk server, but don't see any SNMP messages leaving the server. If the MIB file is specified in your input setup but not present polling will abort for that input.ĭoes your remote device report any errors like bad community name received or login failure, etc? It seems odd that you are specifying snmp_version = 2C but also including v3 auth settings? You just don't see the translation of oid values to key name. py file into the custom mib directory, specify that filename in the SNMP Modular Input data input setup, and you will be able to poll. This ruled out issues with getting the oid number to poll correct.Īs an aside, if anyone has issues compiling their MIB files into python, you can actually drop an empty.

I also found that troubleshooting was a lot easier when going for a standard OID, like sysContact.

I installed on a testbed system without Symantec and the generic network error message in the Splunk log was fixed. Even with the "Proactive Threat Protection" and "Network Threat Protection" disabled via the Symantec GUI, I found that outbound UDP was being denied.

I was using Symantec Endpoint Protection.

if possible, you can install wireshark on the splunk server, and filter for UDP, this will allow you to see the SNMP packets leaving the splunk server and reply, if any, being received.

check the splunkd log, errors will be reported there: \var\log\splunk\splunkd.log.

I've found the process pretty cumbersome and required a lot of troubleshooting, at least from Windows. I can give a couple of things that helped me with the issues I had with SNMP Modular Input.
