Hi Everyone,

I am experiancing the following issue. Everytime I try to configure a service with the check_http command. The services stays in Pending state forever. It does not shedule the next check. Nor does it register the initial check.

  State Type: Hard
  Current Check: 1 of 3
  Last Check: Never
  Next Check: Not scheduled

        use                             CHECK-5MIN,NOTIFY-EMAIL-ADMINS

I hope you guys can shine some light on this. Because I've been trying to solve this issue for a few days now.

Thanks.

If you click on "Schedule an immediate check" on the details overview page does it kick it off?

No it does not.

following up on that. When I click it once, it does seem to retrieve the results. Only the status stays pending. The option for a force-check is no longer available and the status details result is this:

• Service State: Pending
  Duration: N/A
  Service Stability: Changing
  Current Check: 0 of 0
  Last Check: Never
  Next Check: Not scheduled
  Service Notes:Service notifications are disabled

When I click the button view this service in Nagios Core... It shows me the entire service as status: OK ...

First, what version of XI are your running?

I am thinking of 2 possible causes, lets try these.

From the console run the following

Code: Select all

service nagios stop
service ndo2db stop
killall -9 ndo2db
killall -9 nagios
service ndo2db start
service nagios start

If you have the same results, lets make sure we don't have any corrupt database tables, run

Code: Select all

service mysqld stop
/usr/local/nagiosxi/scripts/repairmysql.sh nagios *
service mysqld start

I have performed both actions. However the result remains the same.
Some of the values however have changes (below). The force check now button dissapeared after one click.

• Service State: Pending
  Duration: 15512d 9h 42m 9s
  Service Stability: Unchanging (stable)
  Last Check: 01/01/1970 00:00:00
  Next Check: 01/01/1970 00:00:00

I am running Vmware image with Nagios XI 2011R3.1 licensed.

Thanks for your continued help!

Can you send the output from Admin -> System Profile

I send it to you in a pm message.

Thanks.

This all looks normal.

I'm beginning to wonder if this is related to this bug

I can certainly try the things written in this FAQ. One thing I did notice was that we had a malfunction today with the exact service that we are monitoring. And it send out notifications just like it was supposed to do. In other words, it seems to be working just fine. Only in the Nagios XI interface it shows up as pending.

Thanks!

It is possible that this is the cause, the bug referenced in the link I sent will make the database (that the web page reads out of) update at an extremely slow pace...
