Getting List of the Universal forwarders

ralam — Fri, 03 Jan 2020 16:39:08 GMT

Hi There,

I wanted to get a list of forwarders from the metric logs. The base logs have confused me a lot. Below is the sample.

For the same hostname "hostname=ip-10-142-xx-29.us-west-2.compute.internal", I see different "sourceIp" & "sourceHost".

Now can anybody help me understand which one is the actual identifier for a forwarder - sourceIp, sourceHost or the hostname?

Splunk Base has a nice app for this. Utilization Monitor for Splunk Utilization Monitor for Splunk

Also to answer your question fwdType=ufwill tell you that it is a Universal Forwarder,

If you're using indexer discovery, the DMC on the Master will show you the entire list of forwarders, including those sending internal logs.
