Running check_nagios by ssh

[Andy Shellam (Mailing Lists)]

As a quick thought, you could write a simple Bash/PHP/whatever script to 
grep the response for the "ok" flag (or warning flag) - or even a zero 
process count.

I don't know how Nagios would take over, but if it was a simple case of 
the slave doesn't run Nagios until the primary goes down, then your 
shell script, upon encountering a zero process count from the master, 
could fire up Nagios on the slave - once it detects the primary Nagios 
is up again, it could kill off the secondary?

Just a few thoughts.
