Splunk Search

Find where a forwarder is forwarding too

Hey Guys

I have multiple DMZs with forwarders all over the places that send to specific main forwarders if you like and then onto the indexer, is there a search that anyone knows of that I can run on a host to tell me where that device is set to forward too, I have a few boxs I need to jump on but its would be better if I can run a search as to jumping through hoops to log onto the actual device its self.

Thanks

Hi AaronMoorcroft

assuming your forwarders are forwarding their _internal index, you can use the following search to find the tcpout connection targets for all forwarders:

index=_internal source=*metrics.log* group=tcpout_connections | chart values(destIp) by host

hope this helps...

cheers, MuS

as I said, you need to have the forwarders _internal available. Another way would be to use the REST endpoint /data/outputs/tcp/ but again, this must be done against each forwarder. I would suggest to enable _internal forwarding this would also help in any case of troubleshooting future issues.

That does seem to bring a few up with the expected results but by no means all, do you have any further advice ?

This approach might work even if only the intermediate forwarders are sending their _internal index events; you'd see incoming connections from the various forwarders in the metrics.log.
