Services returning unknown on windows server 2012

[SaltyBear]

Hi

First i'd like to tell you that this is part of a school assignment where I'm studying to be a network engineer so excuse me if I don't understand any terms you might use to help me.

So basic setup is this:
LAN A:
4 servers 3x windows server 2012, 1x windows 7 client, 1 FW and 1 Nagios monitoring server on ubuntu 14.04

I am currently succesfully monitoring the windows client and the firewall as the screenshot will show
But both of 2 windows server 2012's give me the same "UNKNOWN" output for CPU Load, Disk space and explorer.exe checks.
As these are properly monitored on the client, I already eliminated the fact that it would be a problem with the plugins themselves.
Does anyone here have an idea why my 2012 servers are both failing to return any statusses for these 3 monitoring services?

Please do ask any further info you might need, I hope the screenshots I have provided will be of help to you.

Thanks.

Any logs in C:\Program Files\NSClient++ that may be helpful?

Also, can you post the service definitions for the ones that are failing?

For one of the checks that is not working, what output do you get when you test at the command line?

Code: Select all

check_nt -H 192.168.60.2 -p 12489 -v USEDDISKSPACE -l c -w 80 -c 90

or

Code: Select all

check_nt -H 192.168.60.2 -v USEDDISKSPACE -l c -w 80 -c 90

It would be good to see your check_nt command definition.

This is how I have my check_nt command defined

Code: Select all

define command{
        command_name check_nrpe
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

And the service definitions I added in the screenshots I provided, the testclient (Win 7 client) is the one where everything works, the other 2 return me a UNKNOWN error on CPU Load, Disk space on C and Explorer.

This is what I get in the details menu for one of the UNKNOWN values.

couple of things jump out

testclient - is this your windows 7 machine? its running a much older version of nsclient than the two which have failed

you mention 3 windows servers and 1 windows 7 client but have only shown three things being monitored, is one of your 2012 servers working? if so can you confirm the nsclient version for it?

when you installed nsclient++ on the servers did you do it the same for all three?

Testclient is indeed the windows 7 client, and I currently only installed nagios on 2 of the 3 windows 2012 servers, that is why 1 is missing.
I never noticed testclient is using an older version, as I did them all on the same day I don't understand how this could've happened.
And I did install them the same way, using the GUI installer I got from the official website and then adding them to my ubuntu 14.04 nagios server.

This is how I have my check_nt command defined

Code: Select all

define command{
        command_name check_nrpe
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

And the service definitions I added in the screenshots I provided, the testclient (Win 7 client) is the one where everything works, the other 2 return me a UNKNOWN error on CPU Load, Disk space on C and Explorer.

This is your check_nrpe command definition, not your check_nt command definition. Can you please post your check_nt command definition.

[SaltyBear]

Whoops I'm sorry

Code: Select all

define command{
command_name check_nt
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -s Azerty1. -v $ARG1$ $ARG2$
}

Azerty1. being the password I put on the nsclient++ on the client/servers

Edit:
I added an ubuntu host and here the same services also return an unknown status but with the following error which the windows servers do not give
"Check_nt: could not parse arguments"

It is hard to see your screen captures but it looks like some of the service definitions are using a number 1 instead of a lower case l
Take a look at that and see if that is the case, if so change the 1 to a l and that should fix it for you.
