Alternate check interval when state become CRITICAL

[Justin Pasher]

Hello,

(I have included the applicable nagios definitions at the end of the email).

I'm trying to figure out if this is even possible. I am running Nagios 
3.0.6 on Debian Etch. I have some service checks setup to see if a web 
site is still reachable. The check itself is pretty simple. It inherits 
most of the options from a service template (most were the default 
settings out of the box).

Right now, the check happens every 5 minutes. If the check_http exceeds 
the timeout, it changes to a CRITICAL state and the alert is sent. After 
that, it continues to check every 5 minutes to see if the state changes. 
If the state remains at CRITICAL or changes to OK, another notification 
is sent out.

What I would like to do is have the check interval change to every one 
minute when the state become CRITICAL, but keep the notifications at 5 
minute intervals.

Here is an example of the preferred scenario (minute by minute) for a 
service that is down for approximately three minutes.

12:00 - state checked, returns OK
12:05 - state checked, returns CRITICAL, email sent
12:06 - state checked, returns CRITICAL, no email sent
12:07 - state checked, returns CRITICAL, no email sent
12:08 - state checked, returns OK, email sent, resume normal check interval
12:13 - state checked, returns OK

I tried setting retry_interval to 1, but it doesn't seem to affect the 
frequency of the checks after the state become CRITICAL. I think because 
max_check_attempts is set to 1, it wouldn't work as I described anyway. 
The "check scheduling" link in the docs seems to be the place that would 
have the information I need 
(http://nagios.sourceforge.net/docs/3_0/checkscheduling.html), but it's 
under construction.

Is there something else I'm missing, or is this type of scenario not 
possible? Thanks.
