Tag rsyslog messages

Any ideas how I can tag the rsyslog messages sent to the remote server? Cumulus recommends not to use "imfile" module for the logs genrated by rsyslog. So I am not sure if there is any other module that supports this.

You can always tag it on the remote server, based on the same tags that we use in the control files in /etc/rsyslog.d/* ; that's almost certainly the easiest way.

It's also possible to use linux tools to filter before sending the logs remote. I'm traveling at the moment, so I don't have references for that.

If you google, you'll find that just about everybody will tell you not to use imfile or input() to re-process logfiles that are already being written by rsyslogd, because it means the same messages will recursively get processed multiple times.
Thanks Dave. I attempted the following and this works well so far.
cat /etc/rsyslog.d/11-remote.conf

template(name="TEMPLATE" type="string" string="<%PRI%>%TIMESTAMP% %HOSTNAME% cumulus_%programname%%msg:::sp-if-no-1st-sp%%msg%")
action(type="omfwd" Target="" Device="mgmt" Port="514" Protocol="udp" Template="TEMPLATE")

Based on cumulus_ I was able to create files in my logserver.
