Output syslog to external system

So I setup syslog output forwarding per the Splunk docs, but am not seeing anything being sent out nor receiving it on the endpoint.

Here is what I have applied (and have tried w/o a props or transforms just like the example w/o success). This was done on the indexer itself, only light forwarders and tcp syslog servers send data into the indexer.

outputs.conf:

[syslog:webreports_syslog_group]
server = myhostname:514
type = tcp


transforms.conf:

[send_to_webreports]
DEST_KEY = _SYSLOG_ROUTING
FORMAT = webreports_syslog_group


props.conf:

[source::/data/logs/httpd/somesite/access*]
TRANSFORMS-weblog-matrix = send_to_webreports

In the metrics.log I see these entries:

08-19-2010 10:34:04.782 INFO Metrics - group=syslog_connections, webreports_syslog_group:myhostname:514:myhostname:514, sourcePort=8089, destIp=myhostname, destPort=514, _tcp_Bps=0.00, _tcp_KBps=0.00, _tcp_avg_thruput=0.00, _tcp_Kprocessed=0, _tcp_eps=0.00

So curious what the double hostname is in the group area? Not sure if this matters much as the destIP is probably what is used for the connection. I see the doubling up in that line regardless if i have hostname, fqdn or IP.

Also not sure why I see no data being sent out. External system is accessible on tcp/514 from this splunk server.

Thanks for insight.

I suspect your problem lies in transforms.conf. You appear to be missing REGEX = in your send_to_webreports stanza. You can confirm this by looking for the message REGEX field must be specified tranform_name= in splunkd.log.

Thanks! I didn't see any mention of this in the docs, but putting 'REGEX = .*' as part of it worked just perfectly.

If you want to match everything, then I recommend just using REGEX = . There is no need to include the star "*". (This should be just slightly more efficient)

transforms.conf:

[send_to_webreports]
REGEX = .
DEST_KEY = _SYSLOG_ROUTING
