Service latency suddenly through the roof

[Deborah Martin]

Hi, 

I'm running nagios 2.0b4, on suse 9.3. The plan is to upgrade to 3.0.6
(nagios) and SLES10 sp1. 

Recently, during some checking of the data that I collect for SLA reporting,
I noticed the service latency has gone through the roof!

The only recent change I've made is to put ssh checks as a host check. This
was to filter ssh checks away from the service problem web interface 
as we do have to shut nodes down from time to time but we don't want to be
alerted as a service problem.

I then had to introduce check_dummy as the service check (otherwise the
pre-flight check outputs hundred of lines stating the no services was
associated with xxxx host).  The check_dummy service check is only done on a
Sunday once per host as it's a dummy check. I thought this would put less
load on Nagios (please correct me if I'm wrong) 

We regard service problems to only be checks against our databases. 

Does anyone know of what could set this servicelatency to suddenly increase
like this ? 

regards,
deborah
