Getting Data In

Why has source stopped indexing?



I have 2 source A and B (routers), they are sending the data over udp port 514.

all of the sudden, the source B is not indexed anymore.

I have captured the traffic (tcpdump), I can see clearly that the traffic is reaching the Splunk server.

My Splunk deployment is a free license all-in-one server.

any thoughts ?

Do you have more than one interface in the server? If you didn't add any restrictions on firewall or in input configuration (did you check your config with btool?), maybe it's an issue with rpfilter (I assume you're running your system on linux)

  • Please check if your input is still there.
  • Make sure tcpdump shows data for source B.
  • Check for any new configuration added/updated after which data stopped indexing.
  • Check splunkd logs for errors and warnings.
    • index=_internal sourcetype=splunkd CASE(ERROR) OR CASE(WARN*)

I hope this helps!!!
