Service check pending

Posted: Mon Dec 13, 2010 11:59 am

After I upgraded to R1.3G, I get a service check pending on a few of my services. Since it seems to be pending, even though it showed up on the problem board, I can't add comments. I also seem to have a host that shows down, even though when I look at the hosts, all of them are up.

Any suggestions?

You could try scheduling an immediate check in the host/service details pages.

The other thing you might want to do is run this from the command-line just to make sure a second nagios process didn't get spawned from the upgrade:

Code: Select all

killall -9 nagios
service nagios start
If the above doesn't work:
You could also double check the host or service by running it's check command from the command-line: example:
/usr/local/nagios/libexec/check_icmp -H <hostaddress>

You can use this to verify the output that you're getting.

That didn't seem to help my cause much. When I look at the host, it says host check pending, just like the services said the same thing. Even if I reboot the whole server, it doesn't clear up anything that might be going on in the background.

Something told me not to upgrade!

What kind of output do you get when you run the check manually from the command-line?

What specifically would I run from the cmd line?

Something in the format of

Code: Select all

/usr/local/nagios/libexec/check_icmp -H <hostaddress>
The specifics can be determined by going through the Core Config Manager to see what arguments were supplied to the check, and filling them in as appropriate.

it comes back with 'OK', but yet still in the nagiosXI interface, it shows 'service check is pending...'

Can you run the following commands on the command line and send us the output from it?

Code: Select all

tail -50 /usr/local/nagios/var/nagios.log
I'd like to see if Nagios has "orphaned" checks.

Can I have you check to see if the Nagios Core is showing the same issue? Access the core interface by going to http://<yourserver>/nagios. I want to see if the issue is with Core or related to the Xi interface.

Is there any relationship between the checks that are coming back as pending? (For example, are they all using the same check command?)
