nsclient error"UNKNOWN: No handler for that command"

[inas.labib]

Hi Team,

We are trying to execute a batch script in Windows machine from Nagios to get the results from the script executed.

We are getting UNKNOWN: No handler for that command error form Nagios. Port 5666 is enabled between two machines


/check_nrpe -H 10.10.98.24 -t 120 -p 5666 -c check_mon
UNKNOWN: No handler for that command

Attached nsc.ini file for your reference.


Nsclient log error:

Hello,

Based on other threads, it looks to me as though NSClient check scripts cannot use an absolute path (though I may be wrong on this).

Are you able to use your other checks (check_sms, check_gfs, check_freeway)? If not, try the following:

Copy D:\TPN_Monitor_Scripts\TPN_Mon.bat to C:\Program Files\NSClient++\scripts\TPN_Mon.bat
Remove the following line from nsc.ini:

Code: Select all

check_mon="D:\TPN_Monitor_Scripts\TPN_Mon.bat"

Add the following line to nsc.ini in the same place:

Code: Select all

check_mon=scripts\TPN_Mon.bat

then, restart NSClient and let us know if your issues persist.

Thanks for your suggestion. It actually helped in setting up and executing one of the batch script.

/usr/local/nagios/libexec$ ./check_nrpe -H XX.XX.XX.XXX -t 30 -c check_mon1
mysql: [Warning] Using a password on the command line interface can be insecure.
"OK: No Error Found.

IS there any way can we parse the above warning.

============================================================================
Also at the same time the other scripts in the same path were unable to execute which given the nrpe socket timeout error.

/usr/local/nagios/libexec$ ./check_nrpe -H x.xx.xx.xx -t 30 -c check_sms
CHECK_NRPE: Socket timeout after 30 seconds

You would have to modify the batch file to parse that out

Also at the same time the other scripts in the same path were unable to execute which given the nrpe socket timeout error.

/usr/local/nagios/libexec$ ./check_nrpe -H x.xx.xx.xx -t 30 -c check_sms
CHECK_NRPE: Socket timeout after 30 seconds

if you execute the script that check_sms calls on the remote machine, how long does it take to execute?

[inas.labib]

Hi,

The batch script which executed on Windows machines for check_sms takes less than 5 seconds.

Does D:\TPN_Monitor_Scripts\TPN_SMS.bat require any elevated permissions?
