How to negate certain messages based on negation syntax
Clash Royale CLAN TAG#URR8PPP
I want to use negation to stop certain messages to be passed on the rsyslog bassed on the $rawmsg.
Message exaple like:
(root) CMD (LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok)
I tried but not working:
if $rawmsg !contains '(root) CMD ' then ?wcc-logs
& stop
It relates to previous post

You need to group the expression correctly. In script, you need to use "not" instead of "!". Also, the not must precede the to-be-negated expression. So correct syntax is
if not ($rawmsg contains '(root) CMD ') then
?wcc-logs
stop
I have used the parenthesis solely for clarification. I have modernized the if a bit to use the block syntax, which IMHO is easier to grasp.
