Icinga, how to send mail alert to specific group/mail when alert reach certain percentage (I.e: >85%)?

Question is in the title, could someone help, I am little newbie in IC :slight_smile:

That depends on your check.
If your check produces a state change in icinga service then icinga2 can send a notification if configured properly.

ok thatโ€™s what i ld like to do, how to set up the .conf file to set up >green % >yellow >80% >red90% + send alert by mail ?

After setting the thresholds for your check in your service you need to attach a notification object that uses user and/or user group objects.

How to define and attach those objects is documented here:
