Sorry for the self-reply, but the URL posted is incorrect (thanks Sander
for pointing this out).

It should be:

http://dev.servprise.com/nagios/

Thanks,
Kevin

Certain

HARD

somewhere.

as

Should

ASL-licensed

> 3) Event handlers are currently non-blocking.  That is, if you choose
> to
> power on a host, the event handler issues the command to the WebReboot
> Enterprise and then returns control to Nagios.  The WebReboot

> then takes care of powering on the host.  This means the script may
> return in seconds while it may take orders of magnitude longer for the
> host to power up.  The consequence of this is that if your max
attempts
> is too low or timing is too tight, host checks may continue to execute
> while the host is powering up and could put it into an erroneous HARD
> DOWN state.

> How should this be handled?  Documentation for the user on changing
> timing & attempt values?  Or should the event handler insert a
> configurable artificial delay?  The downside of the latter being that
> it
> requires fine tuning for each host, as some boot to the OS quickly
> while
> others do not.

> Anyway, any help this list could provide would be great.  Ultimately,
> the plugin is for Nagios users and we want to make sure we're building
> something that meets your expectations.
