Hi there,

I want to supervise different Windows servers for my company but it doesn't work.

I've installed Nagios Core 4.1.1 with the Nagios plugins 2.1.1 on an Ubuntu server 14.0.4.
I added a Windows Server (2012r2) to the supervision by installing NSCP-0.4.4.19, modified the windows.cfg file, started the nagios service and it worked/s perfectly !

But I have a very big deal when I want to add other Windows servers.
These are 2003r2. I had to download NSCP-0.4.0.172 to be able to install it on the servers but I get it.

When I modify the windows.cfg file and define these servers, they appear on my nagios interface but the infos that I got are the ones of my 2012r2...
I tried to create one windows.cfg file per server (and modify the nagios.cfg one to check) and the problem is still the same.

Can you help me about that ?

Can you post your windows.cfg files so we can take a look at the differences?

Yep, of course !

Here it is.

For the others servers, just change srv-wnd1 by srv-wnd2 or srv-wnd3.

And here is the modifications I've made on the nagios.cfg file.

When you create the new file, and change the host_name, are you also changing the 'address' part? This is what each service depends on -

Code: Select all

define host{
use windows-server ; Inherit default values from a template
host_name srv-wnd1 ; The name we're giving to this host
alias Serveur Web auto-hébergé de GSA ; A longer name associated with the host
address xxx.xxx.xxx.xxx ; IP address of the host
}

Additionally, under each service, make sure you change it here to (the host_name to be srv-wnd2) -

Code: Select all


define service{
use generic-service
host_name srv-wnd1
service_description NSClient++ Version
check_command check_nt!CLIENTVERSION
}

Yes, I changed the address at the same time I changed the name of the server.

I use a search and replace function to modify the file to go faster but I always check all the lines after so I can be sure that all the file are correctly modified.
But in production, all the servers show the information of the first...

Can you please post all three of the different configuration files for us so we can see them? There is most likely something different missing.

I just replace the IP addresses which are confidentials.
But I confirm you that the 3 IP addresses are differents in the config files.

Got it - looks good. Thanks for posting them. I usually trust the replace method, but you never know!

Could you run the following, and post the output? cat /usr/local/nagios/etc/objects/commands.cfg | grep 'check_nt' -A 2 -B 2

I'd like to see how your check_nt command is defined. On my system, for instance it uses this -

Code: Select all

# 'check_nt' command definition
define command{
        command_name    check_nt
        command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$
        }

My guess is you might have it defined statically, rather then taking the $HOSTADDRESS$ variable.

Hey !

Here is the answer for the command you ask me to run :

# 'check_nt' command definition
define command{
command_name check-nt
command_line $USER1$/check_nt -H IPOfThe1stServer -p 12489 -s AdminID -v $ARG1$ $ARG2$
}

So it looks like you're right.

Posted: **Wed Apr 27, 2016 5:08 am**

you have edited your command so that it points ot the IP of a specific server
change it to that it is like the original

Code: Select all

        command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$

see $HOSTADDRESS$ will be substituted with the IP of the server
