I have tested with "trigger major|critical" and "trigger Major|Critical" and "trigger Critical" and "trigger critical"
Try this:
[agecanonix] log:/var/log/messages:10240 trigger WARNING|ERROR log:/home/sirt/log/alarm_tina.log:10240 trigger major|critical
I do not think '%' (pcre) is supported in this file.
that doesn't run :-(
