UNKNOWN: No handler for that command NSClient++

Nagios Nagios 3rd party applications support
#1

Hi,

Im getting the following error when running this command:

 /usr/local/nagios/libexec/check_nrpe -n -H 10.0.0.14 -c check_cpu
UNKNOWN: No handler for that command

The log shows:

2010-03-24 12:23:29: message:NSClient++.cpp:1124: No handler for command: 'check_cpu' 2010-03-24 12:23:29: message:include\NSCHelper.cpp:238: No handler for command 'check_cpu'.
However I know nrpe is working:

/usr/local/nagios/libexec/check_nrpe -n -H 10.0.0.14
I (0.3.7.493 2009-10-12) seem to be doing fine...

Can anyone help my nsc.ini file is below:

ehrm… you are using NRPE to go to another box which in turn sends an nsclient++ request to another server?

or are you trying to use nrpe on a windows client running nsclient++ ?

#3

Hi,

I have a linux nagios server, which is trying to monitor a windows xp client, the nsc.ini file was from the windows client. Hope that makes sense.

#4

you need to use check_nt not nrpe on the nagios server…

Luca

#5

thanks, I have check_nt working, but I thought the nsclient allowed me to also check throug nrpe? I would prefer to use nrpe as I have graphing that works on the name of a service, and as I cant have a service named twice the graphing wont work for the Windows service.

#6

i dont’ know if it’s possible… i never used it on windows.

#7

check_nrpe work fine in windows.

/usr/local/nagios/libexec/check_nrpe -H 10.99.99.99 -c checkcpu
ERROR: Missing argument exception.

This is the format and then you have to define the argument or defince an alias… I copied this from wiki.

#8

I though it did, but I have defined the commands in my config file (shown in the first post) but all i get is unknown handler which I assume means it cant resolve the command.

#9

That part of the ini is for something else I think. You need to do it like in my example or define a command in the alias section,

#10

I have updated my config file too contain:

[External Alias] alias_cpu=checkCPU warn=80 crit=90 time=5m time=1m time=30s alias_cpu_ex=checkCPU warn=$ARG1$ crit=$ARG2$ time=5m time=1m time=30s alias_disk=CheckDriveSize MinWarn=10% MinCrit=5% CheckAll FilterType=FIXED alias_service=checkServiceState CheckAll alias_process=checkProcState $ARG1$=started alias_mem=checkMem MaxWarn=80% MaxCrit=90% ShowAll type=physical alias_up=checkUpTime MinWarn=1d MinWarn=1h alias_file_age=checkFile2 filter=out "file=$ARG1$" filter-written=>1d MaxWarn=1 MaxCrit=1 "syntax=%filename% %write%" alias_file_size=checkFile2 filter=out "file=$ARG1$" filter-size=>$ARG2$ MaxWarn=1 MaxCrit=1 "syntax=%filename% %size%" alias_file_size_in_dir=checkFile2 filter=out pattern=*.txt "file=$ARG1$" filter-size=>$ARG2$ MaxWarn=1 MaxCrit=1 "syntax=%filename% %size%" alias_event_log=CheckEventLog file=application file=system filter=new filter=out MaxWarn=1 MaxCrit=1 filter-generated=>2d filter-severity==success filter-severity==informational truncate=1023 unique descriptions "syntax=%severity%: %source%: %message% (%count%)" alias_event_log2=CheckEventLog file=application file=system filter=new filter=in MaxWarn=1 MaxCrit=1 filter+generated=<2d "filter+eventSource==Service Control Manager" filter+severity==error truncate=1023 unique descriptions "syntax=%severity%: %source%: %message% (%count%)" check_ok=CheckOK Everything is fine! command[check_cpu]=checkCPU warn=80 crit=90 5 10 15 command[check_cdrive]=CheckDriveSize MinWarn=10% MinCrit=5% CheckAll FilterType=FIXED command[check_services]=checkServiceState CheckAll command[check_procs]=checkProcState $ARG1$=started command[check_mem]=checkMem MaxWarn=80% MaxCrit=90% ShowAll type=physical command[check_uptime]=checkUpTime MinWarn=1d MinWarn=1h command[check_ok]=CheckOK Everything is fine!

Restarted the service, but I still get the same error:

/usr/local/nagios/libexec/check_nrpe -n -H 10.0.0.14 -c check_cpu UNKNOWN: No handler for that command

#11

because thats not the syntax. check in the top of the templete

#12

I have tried that too:

./check_nrpe -n -H 10.0.0.14 -c alias_cpu UNKNOWN: No handler for that command

#13

/usr/local/nagios/libexec/check_nrpe -H 99.99.99.99 -c alias_cpu OK CPU Load ok.|'5m'=21%;80;90; '1m'=24%;80;90; '30s'=22%;80;90;

#14

I can see yours works but mine doesn’t and I don’t know why, i have tried it on two different windows servers, so it must be something in my config can you see any obvious mistakes?

#15

perhaps CheckExternalScripts.dll has to be enabled to run alias, dont know. I normllay run scripts but not alias.

#16

that was my problem thanks all is working now!

#17

I had same your issue. Please give me your solution.
