External watchdog for Icinga2

[ken]

I found the answer to my question here:

"Backend icinga is not running" but everything seams fine

Logon to your db and run: use icinga2; select status_update_time from icinga_programstatus; If this is not up to date you’ll get this error. Hence, you’ll need to find out why it is not updated by icinga2.

I just need to write some code around that, and also make sure I don’t mistake a reload or restart for a zombie state.
