Thanks, this helps.
I'm wanting to check if SEC is behind, but also check if the overall log flow
(which involves 3 rsyslog servers I can monitor, and a logstash server I can't)
is keeping up.
As for including the delta in the message, you can do something like:
action=lcall %o -> (sub {perl code here});pipe 'SEC is behind %o minutes. Log
time: $1' /bin/mailx -s "SEC: %t > SEC is behind 1+ minutes." [email protected]
