Re: limit check file alerts

[Marc Rossi]

Thanks for the idea Tino. Unfortunately I don't think that will work as I'm trying to limit the alerts sent to m/monit and I'm not sure what email address to include on the noalert clause to do that (looks like the syntax is "NOALERT <email adddress>".

Seems wrong that in the monit config I can say "if not exists <do something other than alert>" and it still alerts that it doesn't exist.

Marc,

just a simple thought: Define this check with a „noalert“ statement and define an additional one with softer criterions (like „… for 5 cycles…“) which does real alerts?

Cheers!

I have the following "check file" setup to re-create that soft-link and start monitoring the file. Only problem is it still generates a "file doesn't exist" event after 3 cycles before creating the soft-link and a "file exists" event.
