SV: [xymon] bbtest yellow-mystery

[Carl Melgaard]

Hi,

> Yes, that is only for disabling alerting to create a maintenance window. It doesn't stop the checks from occurring. Thanks.
Great, I feel like a beginner now. Is there any day-to-day operations-manual in the Xymon-documentation/wiki somewhere? I think I've missed the basic Xymon operation-guidelines somehow.

I've used the Enable/Disable-options in he Administration-part of Xymon, to disable the tests (the hobbit-enadis.sh-script) - is that just alert-disabling?

But why is the check still running against the AD-host I've disabled? It looks like its that exact dns-check that takes 450 seconds to run (timeout). Looking at the DNS-statistics:

DNS tests executed                          4602546.200466        450.096498

which is the normal checks + the 450 second timeout. All other dns-checks run fine.

Shouldnt I except something like this (from the conn checks):

"System unreachable for 764 poll periods (363317 seconds)"

instead of:

"Service dns on xxx07 is OK
Dialup host/service, or test depends on another failed test
Host appears to be down
Timeout
Seconds: 450.003"

when I've disabled all the checks on the host, and the server is powered down? Or am I missing something here?
