When a plugin is executed by the Nagios process, it is executed by the by the nagios user account.
Can you verify that the plugins can be executed while logged in to the server as the nagios user?
Can you post the directory listing of the folder where the plugins are installed so we can view the settings?

Try changing the group ownership for all of the plugins to the nagios group and then try and run the plugins in question while logged in as the nagios user.
If that fails, we would have to see the commands.cfg file and the config files for those services that are failing. Could you post that?

What you can do is to stop the nagios processes and the defunct one.
Turn on debugging in the nagios.cfg file and start up the nagios daemon and see what types of errors show up in the nagios.debug file.

[lichaofeng]

I set daemon_dumps_core=1 & debug_level=-1 in nagios.cfg ,
and start up the nagios daemon .

Code: Select all

$/opt/freeware/bin/nagios -d /etc/nagios/nagios.cfg

and here is the log file , debug file , and the cfg file . I can not find something useful .

nagios.rar

(47.14 KiB) Downloaded 86 times

I am running nagios on aix 5.3 , does aix supported by nagios ?
I download nagios rpm from perzl.org .

We don't have access to an AIX server so that make it difficult for us to support it. Nagios core works very well on Centos and Redhat if you have access to one of those OS's.

You may want to verify the settings in the nagios.cfg file and make sure that they match where things are installed and running from.

One thing, you may want to enable auto_reschedule in nagios by editing the nagios.cfg file and change the following from

Code: Select all

auto_reschedule_checks=0

to

Code: Select all

auto_reschedule_checks=1

Save and restart nagios

It looks like the checks didn't run and that could be a time issue or with the scheduling settings from above. If you are still having problems, post the following files so we can view them.

Code: Select all

/etc/nagios/objects/commands.cfg
/etc/nagios/objects/localhost.cfg
/etc/nagios/resource.cfg
