Survey of Nagios.

[Pascal Miquet]

Scott,

Do you have any informations or how is this feature configured, I mean
the fact that when nagios die someone is notified ?
Concerning the GSM modem, I'm investigating in how this can be done.
NOTE that we are in french country, and actually I have no idea on HOW
this can be performed.

Thanks for your help.

    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. :)
