Service Alerts and Notifications

[wnorth]

That is actually interesting, when the host goes down I see a HARD service
alert as follows:

HOST ALERT: ebro;DOWN;HARD;5;CRITICAL - Host Unreachable (10.0.33.8)

But for the check_http I only see the following:

SERVICE ALERT: ebro;Website App Server MS2;CRITICAL;SOFT;3;Connection
refused

Once I changed the retry interval to 1 and the max attempts to 1 I saw the
email, so I just wasn't waiting long enough...makes sense. In theory I would
want it to try 3 times in a row, if it fails send an email, then wait 5
minutes and retry again.

For that to work I tried the following: 
max_check_attempts 3
retry_check_interval 5
normal_check_interval 5

This should force it to try 3 times before setting a HARD alert and wait 5
minutes between normal intervals, however that is not what it does, it
appears it sets the retry_check_interval to 5 minutes between non-OK service
alerts, so if I tell it to try 3 times, it will try 3 times and wait
in-between tries for 5 minutes, if I set it to 2 on the retry it will wait 2
minutes in between tries, which comes out to a total of 6 minutes. I'd
rather it fail after a minute or so, so if I set it to 0 it will inherit a
standard minute...the only way to solve this is to set it at a 1 minute
interval and just wait.

Sound about right?

Hi,
	This is kind of stupid/obvious, but

a) I don't see a HARD service alert in your log snip for the service.
Did it actually get to that state?  Your retry interval is 3 min, so it
would take you 15 min or so to get an alert.

b) If it did get to HARD, what was the cmd it tried to run & is that a
valid cmd?

c) Did you kill all the old processes and restart Nagios w/ the new config?

I don't see anything obvious in your cfgs that wouldn't be working.
