Check_WinFile Nagios NRPE help please

[abrist]

That is the right place for your handlers (or aliases, etc).

I will show you how I have mine defined, and that it works properly, then you can duplicate the configuration:

In the NSClient.ini file I have the following defined under External Scripts section, "this will be different since you are using the latest NSClient++ version and not the recommended 0.3.9.x version. Though it should still function in this respect:

Code: Select all

check_winfile= scripts\check_winfile.exe --target C:\PerfLogs\Admin\C --warn 1 --critical 3

I then call this from my Nagios server's terminal with the following:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 192.168.5.63 -c check_winfile

And it output this:

Code: Select all

FILE OK - 1 files to consider|'selected files'=1;1;3; 'all files'=1 'deleted files'=0

Now, if this plugin can be assigned arguments I would recommend placing $ARG3$ and $ARG4$ instead of hard coded critical and warning values, if you plan to change these in the future, in that way, you can change them from your Nagios server and not have to log into the Windows workstation.

Thanks, I assume

/usr/local/nagios/libexec/check_nrpe -H 192.168.5.63 -c check_winfile

is a commands.cfg change?

And then the arguements would go into the windows.cfg config:


define service {

host_name CSXENCLUFS
service_description File Count
check_command check_nrpe!check_winfile $ARG1$ $ARG2$
use generic-service
notification_interval 0
}


Thanks, I have made the changes to the commands.cfg file and waiting for the refresh.

I meant you could run that command as a test from the nagios server's console, before you configure command and service definitions, that way, you know it works. That is not how the command definition should look. When you run the command, "filling in your windows server's IP and not the example IP" what does the console return?

[csward]

Ah, right. I'm getting a "No handler for command: scripts\check_winfile.exe" error when I do this now.

[abrist]

There must be something amiss with your alias/external script declaration. Could you post your entire nsclient config in code wraps? (feel free to obfuscate your password and other sensitive bits)

[csward]

Thanks:

Code: Select all

# If you want to fill this file with all avalible options run the following command:
#   nscp settings --generate --add-defaults --load-all
# If you want to activate a module and bring in all its options use:
#   nscp settings --activate-module <MODULE NAME> --add-defaults
# For details run: nscp settings --help

How are you running the command from the Nagios server? Can you paste exactly what you are typing into the command line? Obfuscating any IP/passwords you wish to not share. Also, are you sure that the check_winfile.exe plugin exists in the scripts directory of NSClient++? And also that you are indeed using the .exe version and not the .pl?

[csward]

Yes, for sure using the .exe version i placed in the "scripts" folder.

I have adjusted the INI file to:

; Check File Count
check_winfile = "C:\Program Files\NSClient++\scripts\check_winfile.exe" --target C:\\Traces --warn 5 --critical 25


and the command I'm using in the Nagios server terminal is:

administrator@CSP-NAG-P01:/etc/nagios/objects$ /usr/local/src/nagios-plugins-1.4.16/plugins/check_nrpe -H 10.20.20.98 -c check_winfile
No handler for command: "C:\Program

Alright, lets move back a few steps. Firstly you do not need to change the definition to the full directory path, you need only use the definition I showed above. Secondly, open a command prompt on the windows server and move to the NSClient++ directory:

Example:

Code: Select all

cd C:\"Program Files"\NSClient++

Then run the following command from that location:

Code: Select all

nscp settings --generate --add-defaults --load-all

You should see some text output telling you it is working on expanding the configuration file..

Once that completes you should now have a fully expanded NSClient++ configuration file, please send that file our way.
