Survey of Nagios.

[Scott]

Okay, I see where this is heading.. basically, as I think I was discussing
this with somebody else on this list, have a GSM modem attached to the
server directly. When nagios dies it sends a page to a designated
person(s).. This is not part of Nagios itelf for obvious reasons in that
it cant monitor if it is not alive to monitor...
The downfall of this is that the contacts have to be hard coded outside
nagios (unless somebody wants to write a parser for the contacts.cfg) but
this isnt really a problem unless you have a quick turnover of
staff/sysadmins. :)
