====== Monit Examples ======

  * [[Monit]]

==== Reminders ====

Keep sending reminders that a service is broken.

Since the default for our setup is every 2 minutes, once every day would be 720 cycles.

Once a day:

<code>
... alert with reminder on 720 cycles
</code>

Every half hour:

<code>
... alert with reminder on 15 cycles
</code>

Every hour:

<code>
... alert with reminder on 30 cycles
</code>

Twice a day:

<code>
... alert with reminder on 240 cycles
</code>
==== Apache ====

<code>
check process apache with pidfile /var/run/apache2.pid
start program = "/etc/init.d/apache2 restart" with timeout 60 seconds
stop program = "/etc/init.d/apache2 stop"
if cpu > 60% for 2 cycles then alert
if cpu > 80% for 5 cycles then restart
if 5 restarts within 5 cycles then timeout
</code>
