Getting Data In

Why is output stopping all outputs routing when a 3rd party server goes down?

Path Finder


I am getting a weird issue. If the syslog server fails, it stops all data being indexed by the default TCP out, and then Splunk fills its buckets and falls over. Am I missing something to set it to continue if it can't connect to a output.

cat outputs.conf


defaultGroup = xxxxx_indexers


server =

type = tcp

timestampformat = %Y-%m-%dT%T.%S

cat transforms.conf




FORMAT = xxxclusterindexers


SOURCE_KEY = MetaData:Sourcetype

REGEX = (fgttraffic|fgtutm)


FORMAT = xxxx_indexers

cat props.conf


TRANSFORMS-routing = mehRouting, Routing_firewalls


TRANSFORMS-routing = mehRouting, Routing_firewalls

Hi @lukessi,

Can you please provide your full configuration from outputs.conf because I can't see xxx_cluster_indexers in your outputs.conf

confirmed if I loss the 3rd party syslog, it stops forwarding to our indexers as well.

Based on answer , it looks like known issue when you'll send data to syslog over TCP. Splunk stops sending data to indexers as well when syslog server is down, better to switch it to UDP or raise case with splunk support.

Ah yes its picked up from the default index app we have...


useACK = true

defaultGroup = xxxclusterindexers

disabled = false


server = index1:9997,index2:9997
