.bat files via nsca on nscp 4.0.170

Hello everyone i've set up my nagios now and everything is working fine with the nsclient. At the moment im only using nsca and everything seems to be ok. The only thing i dont get is how i include .bat scripts in my nsclient.ini config, without getting errors in the nsclient.log. I have tried a lot, but always got the error:

2012-05-08 11:24:15: e:..\..\..\trunk\service\NSClient++.cpp:943: No handler for command: scripts\check_fb.bat avalible commands: commands {, a-check-win-cpu, a-check-win-disk, a-check-win-fb, a-check-win-ram, a-check-win-service, check_eventlog, check_eventlog_cache, check_nscp, check_ok, checkalwayscritical, checkalwaysok, checkalwayswarning, checkcounter, checkcpu, checkcritical, checkdrivesize, checkeventlog, checkeventlogcache, checkfile2, checkfiles, checkfilesize, checkmem, checkmultiple, checkok, checkprocstate, checkservicestate, checksingleregentry, checkuptime, checkversion, checkwarning, checkwmi, checkwmivalue, listcounterinstances, nsca_exec, nsca_forward, nsca_help, nsca_query, nsca_submit}, plugins {, 0, 1, 2, 3, 4, 5, 6, 7}

2012-05-08 11:24:15: e:..\..\..\..\trunk\modules\Scheduler\Scheduler.cpp:122: Command was not found: a-check-win-fb

and i couldnt find a sample for including .bat files via nsca (>= 4.0 ) anywhere.. :S (found only threads about previous versions..) Im sure im doing it wrong so posting my current config would not make sense... Anyone who could show me a little sample? maybe with a .bat with 2 arguments? :)

Not sure if you are upgrading from previous version. But if so you can use the old config and/or upgrade the old config.

If not using old config I would recommend the following approach: Edit you nsclient.ini like so:

[/modules]
CheckExternalScripts=1

(yes, very short)

Then run:

nscp settings --generate ini --add-defaults

And it will fill your config with available keys.. You will find a section called something along the lines of: /settings/external scripts/scripts where you can add key=script. Key will be you nsca/nrpe command and script will be the script you want. There is also a few simplification you can do by using something called wrapped scripts...

If you want I can create an example sample when I get home (dont have nsclient++ at work)...

Thank you for quick answer!

well i can show you what i've configured, so its probably easier to see whats wrong.. how i alrdy said.. the other things work fine :)

im new to nagios, im not using an old config.. im trying to get it running now for 3-4 days and it now im at a point where im stuck. :) i try to include a check_fb.bat which i put in the scripts folder.. the check_fb accepts 4 Arguments, the first two are Paths.. the 3d is the warn value and the 4th the crit value... just to let you know...

Message #2570
aliases and script are different: [/settings/external scripts/alias] is used for "internal command" and [/settings/external scripts/scripts] is used for external (batch/vbs/exe/*) commands...

So just move a-check-win-fb over to the .../scripts section and you should be good to go...

Once your done start nsclient++ in test mode:
```
nscp test
...
commands
...
a-check-win-fb
...
```

  Thank you! i now finally see the nsclient is sending back sth to the nagios server. But now i've got this error
```
2012-05-08 14:24:28: e:d:\source\nscp\trunk\modules\checkexternalscripts\commands.hpp:89: Failed to parse arguments for command 'a-check-win-fb', using old split string method: unknown escape sequence: scripts\check_fb.bat "C:\Program Files (x86)\Firebird\Firebird_2_5\bin\" "C:\Programme3\TopControl\Fruitmanager\Daten\" "10000" "20000"
```
  u maybe know what this could mean?

    It is not an error per see... It uses parsing when it parses the command string so \ is an escape character...
    
    hence: foo\bar should be: foo
    bar and so on and so forth. Since this is "new" in 0.4.0 if we fail to parse we will read it all as space separated strings (and give that error message).
    
    It should work any way unless you are using "" and such...

    now i get
```

```
    i get this error msg at the Nagios-Server in the syslog:
```
Name: 'martinpc', Service Description: 'fb_check', Return Code: '0',
Output: 'Die Syntax für den Dateinamen, Verzeichnisnamen oder die Datenträgerbezeichnung ist falsch. #015#012OK! Transactiondifferenz = 2 / WarningT = "10000" / CriticalT ="20000"'
```
    if i call the fb_check manually i get as msg:
```
OK! Transactiondifferenz = 2 / WarningT = "10000" / CriticalT ="20000"
```
    and the echo command in the .bat file is
```
echo OK! Transactiondifferenz = %VarGesamt% / WarningT = %varWarnT% / CriticalT = %varCritT%
```
    seems that the nscp is converting the echo in the wrong way or sth like that??

      NSClient++ doesn't really convert anything at all... I would (but I havent seen the script) guess the script has some issues...
      
      The data could very well come before the echo so the problem could be earlier... try adding in some more echos here adnt there to see if you can find where it is caused...

        Its strange because if i open the console and go to the directory of the bat.. and execute the command manually.. it seems to work?!
        
        check_fb.bat "C:\Program Files (x86)\Firebird\Firebird_2_5\bin\" "C:\Programme\TopControl\Fruitmanager\Daten\" 10000 20000 >> C:\log.txt
        and in the log.txt i see then:
        
        OK! Transactiondifferenz = 2 / WarningT = 10000 / CriticalT = 20000

        The path i set was wrong, now all is working, but the error remains..
        
        Thank you anyway!

        I get the error only once, when im starting/restarting the nscp service:

        But the bat is working and the results seem correctly.
