Error in windows.cfg that I can't seem to find

Nagios Nagios Configuration support
1

Hello all–

I have Nagios 3.0b4 runnig on an Ubuntu 7 box. I followed the quickstart guide and I’m able to monitor the few printers I have set up so far and the local host.

I installed and configured NSClient++ 0.2.7 on my machine and followed the quickstart guide to set up Nagios to monitor my machine.

When I run the verify switch for Nagios (/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg) to make sure everything’s OK, I get the following:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Reading configuration data…

Error: Could not find any hostgroup matching ‘allhosts’ (config file ‘/usr/local/nagios/etc/objects/windows.cfg’, starting on line 25)
Error: Hostgroup has no members (config file ‘/usr/local/nagios/etc/objects/windows.cfg’, starting on line 47)

The problem is, there’s no such line in my windows.cfg file:

any thoughts?

I’m having this same problem, I can’t seem to figure out whats wrong with my files either. I noticed in yours, you defined the device you’re monitoring as windows-server, then in hostgroup_name you’re using wndows-servers. I had that at first and then changed them both to windows-server, but it didn’t fix my problem.

3

I think the first windows_server is just the monitoring template, not the host group… not sure though.

I’m in the process of upgrading to 3.0b5 to see if that helps. I noticed that there are some bug fixes in the config files, so what the heck…

4

If you find that this fixes the problem, post here with any changes you made.

5

Found it:
In templates.cfg, remove the ‘allhosts’ reference from the windows_server section. ran the verify with no errors, reloaded and it’s working fine.

6

Yup, worked for me too, thanks.

I’m still having the following error in the web interface:

Web interface gives me Error: Could not read host and service status information! when I try to go to anything under Monitoring, and most of the stuff under Reporting.

Any idea how to fix this?

7

did you edit the NSC.ini file on your windows machine?

I uncommented all the dlls except WMI and remote config.

8

Yup, did that step, uncommented the same dlls.

9

I know these are obvious, but…
you installed the service?
installed the systray icon?
started the service?

are you able to get reports on the nagios machine itself?

10

Service installed
Systray icon is there
service is started

not sure how to view the reports on the nagios machine
