Examples
Receive email alarm on Weekends
For monitoring on the weekend you might have:
end date/time greater than or equal to -1 minute AND alarm frames greater than or equal to 1 AND Weekday equal to Saturday OR Weekday equal to Sunday AND alarm frames greater than or equal to 1 AND date/time greater than or equal to -1 minute
Choose "email details upon match" in the filter. For more details see Email
Receive email for specific monitor on Sunday
Monitor id equal to ### AND Cause not equal to Signal AND End Date/Time greater than or equal to -1 minute AND Alarm frames greater than or equal to 10 AND Weekday equal to Sunday
Run filter from the command line
From the forum:
You can use cron job to run the filter. Don't check the run in background box .. then in cron job run zmfilter.pl --filter_id=[whatever the id is].
Run a filter from the command line (alt.)
From the forum:
sudo zmdc.pl status zmfilter .pl --filter_id=2 --daemon to see what zmdc.pl thinks about it. sudo zmdc.pl start zmfilter .pl --filter_id=2 --daemon Is basically how to web ui tells zmdc.pl to run it, so running that from command line should do the same thing. ps ax | grep zmfilter should either list it or not.
Play audio notification upon alert
