Hello,

I am running version 4.0.4 of Nagios core and 0.3.9 of the NSCIient++ on a windows 2012 R2 server. I can issue the following command manually from the nagios server, but the web interface shows the check_nt: Could not parse arguments error.

root@nagioshost:/usr/local/nagios/etc/objects# /usr/local/nagios/libexec/check_nt -H 10.10.20.10 -p 12489 -v MEMUSE
Memory usage: total:4799.59 Mb - used: 1394.62 Mb (29%) - free: 3404.97 Mb (71%) | 'Memory usage'=1394.62Mb;0.00;0.00;0.00;4799.59

here is the check_nt section from command.cfg

Code: Select all

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

This is actually my second domain controller on a subnet, the first one is identically setup and reports just fine. I have tried 0.4.3 client as well, but the same results. Below is the windows.cfg section for both working and non-working servers:

Code: Select all

define host{
        use             util-server     ; Inherit default values from a template
        host_name       DFPDC01 ; The name we're giving to this host
        alias           Deltrol's fluid domain ctrl 01  ; A longer name associated with the host
        address         10.10.20.9      ; IP address of the host
        }

define host{
        use             util-server     ; Inherit default values from a template
        host_name       DFPDC02 ; The name we're giving to this host
        alias           Deltrol's fluid domain ctrl 02  ; A longer name associated with the host
        address        10.10.20.10      IP address of the host
        }

Any help would be appreciated.

Thanks,

Mike

Can we see the service check definition? The host check definition doesn't tell us much.

Can you run the command as nagios?

Code: Select all

su nagios
/usr/local/nagios/libexec/check_nt -H 10.10.20.10 -p 12489 -v MEMUSE

Please post the output.

Can you please provide the MEMUSE service check definition.

I suspect it's this line in your host config:

Code: Select all

address        10.10.20.10      IP address of the host

There is no semi-colon to start the comment. It should be:

Code: Select all

address        10.10.20.10     ; IP address of the host

I suspect this is the reason for "Could not parse arguments"

Code: Select all

./check_nt -H 10.10.20.10      IP address of the host -p 12489 -v MEMUSE -w 80 -c 90

check_nt: Could not parse arguments
Usage:
check_nt -H host -v variable [-p port] [-w warning] [-c critical]
[-l params] [-d SHOWALL] [-u] [-t timeout]

Thanks so much, that was it!

It is amazing how long you can look at this stuff and not see the obvious that is right before your eyes!

Thanks again,
