how can I receive alerts for every new trigger matched for 'LOG'

hi, there, I have a LOG check for "error: #1" "error: #2" in a log file. We'd like to receive email alerts for each every trigger matched, "%error: #" since we needs to know the all the error # reported. Right now, it generates email alerts. but not for every new triggers. No alerts are generated for a newly matched trigger log entry if the STATUS is red/yellow already. In my thinking, if the LOG check itself can be RECOVERED after 5m (I believe the default is 30m), this ought work.

• Does anybody know how to change the default from 30m to 5m (for a single check/test)?
• Any alternative/recommendations to get the desired results? I initially thought a 'creative' combination of 'REPEAT=5 DURATION<10' would do it...
