Nagios Support Forum

Hello,

I was looking at cloning our older physical nagios server to a vm in order to free up this hardware. The clone completed fine with the vmware vcenter converter software. I do have the clone up and running and can connect to the web gui, but it shows "Unable to get process status" on that page. We are running version 4.08.

The service is running if I run ps ax | grep nagios
4292 ? Ss 0:00 nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
5900 pts/o S+ 0:00 grep nagios

Is there something else I need to reconfigure in order to get this to work in a VM? I'm not real familiar with nagios yet so any help is appreciated!

Thanks!

For some clarity here, could I ask you to post a screenshot of the error? There shouldn't have been complications switching over.

Sure,

Here's what it is showing in Chrome:

What does service nagios status come back with?

Ok, it looks like the actual nagios service didn't start maybe, just nrpe. When I do a check on this I see the following:

[root@nagios etc]# service nagios start
Starting nagios:CONFIG ERROR! Start aborted. Check your Nagios configuration.
[root@nagios etc]# service nagios status
No lock file found in /usr/local/nagios/var/nagios.lock

oops meant to add this:

[root@nagios etc]# nagios -v
nagios: error while loading shared libraries: libltdl.so.3: cannot open shared object file: No such file or directory

Can you try to run a /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg and see what happens?

Sure, this is what it shows me:

***> One or more problems was encountered while processing the config files...

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

So I wonder if some of the config files were corrupted in the conversion, I wouldn't think so, but I guess you never know.

I went ahead and removed the offending line in the one cfg file, stopped nrpe and restarted it but still get the lock file warning when trying to stop the nagios service.

Stopping nagios: No lock file found in /usr/local/nagios/var/nagios.lock

I looked at that directory I don't see a nagios.lock file:

drwxrwxr-x 5 nagios nagios 4096 Aug 24 14:37 .
drwxrwxr-x 9 nagios nagios 4096 Jun 30 2011 ..

However, I don't see one when I look on the old physical server either.

Try running the verification below and fix any errors. As soon as there are no errors, start nagios by running the following.
