[Pkg-nagios-devel] Bug#667615: nagios-nrpe-server: computes wrong number for "check_procs -a"

[Teodor]

Package: nagios-nrpe-server
Version: 2.12-4
Severity: normal

Hi,

Running 'check_procs [..] -a' directly on a host gives the correct number:
| H:~# /usr/lib/nagios/plugins/check_procs -c 1:1 -a SOME_UNIQUE_ARGUMENT
| PROCS OK: 1 process with args 'SOME_UNIQUE_ARGUMENT'
|
| H:~# /usr/lib/nagios/plugins/check_procs -c 1:1 -a ANY_RANDOM_STRING
| PROCS CRITICAL: 0 processes with args 'ANY_RANDOM_STRING'

Running the same command indirectly via 'check_nrpe' gives a wrong number:
| H:~# /usr/lib/nagios/plugins/check_nrpe -H $DST -c procs-a -a 1:1 SOME_UNIQUE_ARGUMENT
| PROCS CRITICAL: 2 processes with args 'SOME_UNIQUE_ARGUMENT'
|
| H:~# /usr/lib/nagios/plugins/check_nrpe -H $DST -c procs-a -a 1:1 ANY_RANDOM_STRING
| PROCS OK: 1 process with args 'ANY_RANDOM_STRING'

where 'procs-a' remote command is defined like this in nrpe server:
command[procs-a]=/usr/lib/nagios/plugins/check_procs -c $ARG1$ -a $ARG2$

As you can see 'check_nrpe' computes the wrong number (+1) for every
"check_procs [..] -a" command. This appears to be specific to Debian
because the 'nrpe' server on RHEL hosts give the correct number.

Thanks
