I believe it will be a good useful feature to allow users to define local/global variables so that update in individual conf file or one place update of global variables will enable configuring the external server IP and Port.
I plan to use a static IP in the .66-MgmtMsgsLogging.conf. When IP and Port are updated then using the script i will replace them. When enable option is given then the comment in front of action will be removed. To disable add the # back. #action(type="omfwd" Target="10.10.10.10" Port="0" Protocol="udp" Template="ForwardFormat") #action(type="omfwd" Target="11.11.11.11" Port="0" Protocol="udp" Template="ForwardFormat") Thanks and Regards Lak. ________________________________ From: Rainer Gerhards <[email protected]> Sent: Tuesday, April 24, 2018 8:23 AM To: rsyslog-users Cc: David Lang; putcha narayana Subject: Re: [rsyslog] Urgent, need help with correct usage of local variables in an action Of you insist on using local variables, the answer is: no, this does not work.

I am seeking help w.r.t the config file with a provision to use local variables so that they can be updated/configurable by user.
