I run the munin monitoring application on my debian Wheezy server and I would like to test the alert-email-notification procedure. To do that, I add in munin.conf the following line:
df._home.warning 25
I set 25 because the df command returns 30 for /home.
I also defined one contact:
contacts me
contact.me.command mail "munin test ${var:host}" my_email@my_isp.com
Unfortunately I don't receive any mails.
There are no errors in the logs. Note that I use exim4 to send emails and that I can send emails from a terminal.
What could be wrong in my configuration ?
Note also I ckecked manually the df plugin:
munin-run df
returns 30 for /home
