NSClient++ Help (#1) - Unable to execute LUA script via NRPE (#578) - Message List
Hi!
I've written a command as a LUA function and I'm trying to query it from remote Nagios box via NRPE, but any attempt failed so far.
Just to check if the problem is anyhow bound to my function, I've made the same tests with standard lua_debug function, ending up wit
The function is available in /test mode:
[...] l NSClient++.cpp(438) Enter command to inject or exit to terminate... lua_debug a1 a2 d NSClient++.cpp(1073) Injecting: lua_debug: a1, a2 d NSClient++.cpp(1109) Injected Result: OK 'hello' d NSClient++.cpp(1110) Injected Performance Result: OK:hello
But if I try to call it from Nagios box I get:
$ ./check_nrpe -H 10.0.0.81 -p 5666 -c lua_debug -a a1 a2 UNKNOWN: No handler for that command $
Other NRPE checks work as expected. 10.0.0.81 is the right IP address.
There's something I'm overlooking? Any clues? Thank you.

I'm sorry for bad formatting. The test output is:
[...] l NSClient++.cpp(438) Enter command to inject or exit to terminate... lua_debug a1 a2 d NSClient++.cpp(1073) Injecting: lua_debug: a1, a2 d NSClient++.cpp(1109) Injected Result: OK 'hello' d NSClient++.cpp(1110) Injected Performance Result: '' OK:hello
While the remote check via NRPE is:
$ ./check_nrpe -H 10.0.0.81 -p 5666 -c lua_debug -a a1 a2 UNKNOWN: No handler for that command $
thank you

Could you check the log from when you run from check_nrpe?
A good idea is to "stop" the service and use "NSClient++ /test" when you run from check_nrpe as that will give you any errors and such.

I have stopped NSClient++ as a service and started it on the terminal with /test option. Now it's answering to lua_debug command as expected:
$ ./check_nrpe -H 10.0.0.81 -p 5666 -c lua_debug hello $
and the log reports:
2010-05-14 14:19:07: debug:NSClient++.cpp:1073: Injecting: lua_debug: ciao, mondo 2010-05-14 14:19:07: debug:NSClient++.cpp:1109: Injected Result: OK 'hello'
The NSC.ini contains:

But it still does not work when you run as a service? (should not make difference really)

Exactly, as you can see here:
# ./check_nrpe -H 10.0.0.81 -p 5666 -c CheckDriveSize -a ShowAll MinWarnFree=1 MinCritFree=1 Drive=c: OK: c:: 52G|'c:'=55884980224B;320070287359;320070287359; # ./check_nrpe -H 10.0.0.81 -p 5666 -c lua_debug -a a1 a2 UNKNOWN: No handler for that command #
If restarted from the command line with /test, everything works as expected:
# ./check_nrpe -H 10.0.0.81 -p 5666 -c CheckDriveSize -a ShowAll MinWarnFree=1 MinCritFree=1 Drive=c: OK: c:: 52G|'c:'=55885119488B;320070287359;320070287359; # ./check_nrpe -H 10.0.0.81 -p 5666 -c lua_debug -a a1 a2 hello #
Just stopped the service from windows services panel and started it from the command line.
I'm using NSClient++ Version: 0.3.7.493 2009-10-12, Plattform: w32
