Nagios Support Forum

our old nagios server took a dump, rebuilt the server on ubuntu, installed from packages (not source). Migrated all the files over and modified as needed.

However the check_nt command i cannot un-comment because i get the below errror. I have searched EVERYWHERE and cannot find where the duplicate check_nt command is.


Warning: Duplicate definition found for command 'check_nt' (config file '/etc/nagios3/conf.d/commands.cfg', starting on line 304)
Error: Could not add object property in file '/etc/nagios3/conf.d/commands.cfg' on line 305.
Error processing object config files!


Secondly,


The check_nt command is using port 1248 however the existing server was using port 12489 (the agent on all the windows boxes are using 12489), once again i cannot find where this is defined at all.

Any help will be appreciated.




NOTE: I have uploaded my commands.cfg file. Please let me know if you need another file or more info.

Version of Nagios Core Nagios Core 3.5.1

Hello and welcome to the Nagios Forum!

It will likely help to search for the extra check_nt command like this

this was the output


/etc/nagios3# grep "command_name.*check_nt" -R /etc/nagios3
/etc/nagios3/conf.d/commands.cfg:# command_name check_nt

is your nagios.cfg pulling in a file from outside /etc/nagios3 ?

no it is sitting in /etc/nagios3


I have attached it here.

:/etc/nagios3# ls
apache2.conf cgi.cfg commands.cfg conf.d htpasswd.users nagios.cfg nagios.cfg.save resource.cfg stylesheets



root@dalsrvitmon03:/etc/nagios3# grep cfg_dir nagios.cfg

here is the nt.cfg file.

this is your culprit. it doesn't have a port set (-p 12489) which will use the default 1248

AWESOME! i see the info starting to populate starting to say could not fetch info from server...


Now that ncsp++ config file... Is there a way to change the allowed hosts en mass? or is it 1 by one?


Now my next problem....
All my servers for CPU Load, C drive, E drive says missing -l Parameters.

Unfortunately one by one.

Can you give an example of the check_command line for one of these services So I can see how they are configured?

We likely need to change the check_nt command to match how your services are setup.

Here is my services.cfg file. Not sure where this is set at, as i inherited this system, and have never used nagios before.

Let me know if these are what you need.
