Hi,
One of our AD-servers went down for maintenance for 1 week, and I disabled the conn+dns tests in Xymon for that period. Now the "bbtest" column suddenly goes yellow, and indicates that DNS lookups takes 450+ seconds now (indicating that the DNS-check for the maintenanced server is still active).
If I check the DNS-check on the server I get this:
" clear Mon Jul 12 09:56:38 2010 dns ok : Ping failed, or dialup host/service
Service dns on xxx07 is OK
Dialup host/service, or test depends on another failed test
Host appears to be down
Timeout
Seconds: 450.004
"
Even tho its disabled. Its been like this since the instance the server was disabled. How can I fix this?
Regards,
Carl Melgaard.

No, it indicates that the Xymon server is taking a long time to resolve host names to IP addresses. You may need to configure the DNS client settings on the Xymon server (e.g. adjust the 'server' parameters in /etc/resolv.conf).
If you have most IP addresses hardcoded correctly in bb-hosts, you may want to add the 'testip' flag to the relevant lines of bb-hosts.

Hi Carl... You can check the "bbtest" page on yout Xymon server and take a look at the "DNS Statistics" section to gain a little more insight to what appears to be a dns resolution/timeout issue.
If you are indeed experiencing dns resolution issues as Buchan suggests, you might consider doing what I do on my Xymon servers - I generally install djbdns, a small, fast, caching name server on my Xymon servers which reduces the load on the network's main dns server, and also significantly speeds up the dns tests.
Not to argue with Buchan, but I'd generally recommend against using testip if possible only because it will just cause more work down the road if/when a server, or system has an IP address changed. (it happens)
Having said, that, I'd also say that using "testip" as a troubleshooting tool can be helpful, but I would remove it once you have isolated and have solved the real cause of your dns symptoms.
Hope this helps.

Hi,

If you have most IP addresses hardcoded correctly in bb-hosts, you may want to add the 'testip' flag to the relevant lines of bb-hosts.
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?
/melgaard
Have you disabled alerting for that host or commented it out in your bb-hosts? The way to disable a "check" for a host is to remove the check or comment out the host in the bb-hosts. If you have just disabled the "alerting", then it will continue to do the "check", just not alert you.

Yes, that is only for disabling alerting to create a maintenance window. It doesn't stop the checks from occurring. Thanks.

There was a book called "Hobbit RTFM" created using LaTeX by me. it is a book composed of Henrik's documentation(html,troff material etc) with Table of Contents and index. I showed him a while back. This is quite labor intensive even I only try to put the existing docs together.
The book should be renamed to "Collection of Xymon Docs". so nobody will got offended.

Josh didn't mean to be rude.
There was a book called "Hobbit RTFM" created using LaTeX by me. it is a book composed of Henrik's documentation(html,troff material etc) with Table of Contents and index. I showed him a while back. This is quite labor intensive even I only try to put the existing docs together.
The book should be renamed to "Collection of Xymon Docs". so nobody will got offended.

Hi,
Have you disabled alerting for that host or commented it out in your bb-hosts? The way to disable a "check" for a host is to remove the check or comment out the host in the bb-hosts. If you have just disabled the "alerting", then it will continue to do the "check", just not alert you.
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?

No, it indicates that the Xymon server is taking a long time to resolve host names to IP addresses. You may need to configure the DNS client settings on the Xymon server (e.g. adjust the 'server' parameters in /etc/resolv.conf).
If you have most IP addresses hardcoded correctly in bb-hosts, you may want to add the 'testip' flag to the relevant lines of bb-hosts.
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?

Also, this documentation project is not approved by xymon community. Me and my other co-worker are the only end-users of this doc.
When ideatorrent is back online, I will re-submit this documentation idea(using latex) to ideatorrent.
From there, we can see other alternative solutions from other people.
This will my last post on this email thread, sorry this should have gone to developer or with other subject in xymon user M.L.

"Disable" is kind of a misnomer, because as You found out it doesn't stop Xymon from running the test - it only means that it won't bother with sending out the alerts.
The main reason for this is that without running the test, Xymon couldn't implement the "Disable until OK" feature (which I find is really handy).
A second reason is that programming-wise it is actually a lot easier to just run all the tests.

I normally run into this I believe when I have a server that is down or that is no longer in the DNS. No longer in the DNS makes sense, but I'd expect it to fail immediately. Anyhow, I'd look to see if a host you no longer have is in the configuration still.
