Dependency issue

[Tedman Eng]

If Service B happens to be queued to be checked before Service A is, you'll
get notified of it's problem first, so that's why it's only sometimes that
you get this behavior.

As for simple solution to your question, increase the max_check_attempts of
Service B/C, so that Service A will error out before Service B/C does, thus
skirting the check queue phenomenon.

Subject: [Nagios-users] Dependency issue


Hi,     

I have setup dependencies which all seem to work fine to a point. 

Example : I have 1 host with 3 services 

                    HOST A 
                        | 
                    Service A (master service) 
                        |
            -------------------
            |                            | 
    Service B            Service C 

If service A  fails, checks and notifications are suppressed for Service B
and Service C which is fine. 

However, i've had a couple of situations where Service B or Service C may
fail first, generate an alert AND then Service A fails which also generates
an alert. 
Is there a way in Nagios that can flip over to only alerting for Service A
in this situation and supress anything for Service B and Service C until
recovery occurs. 

Do I need to define further service dependencies or use inheritance of
parent ? I've read the docs (several times) but can't seem to find the
answers there. 
                       
I'm using Nagios 2.0b4 / Suse 9.2. 

Any help, pointers to docs that can help, or even a padded cell would be
much appreciated! 

regards,
deborah
