[Pkg-nagios-devel] Bug#565643: nagios-nrpe-server: same return code for "plugin not found" and "status critical"

[Michael Banck]

Package: nagios-nrpe-server
Version: 2.12-1
Severity: normal

Hello,

if a NRPE client requests a check for a plugin/command which is not
configured in nrpe*.cfg, the same return code (2) as for a critical
service status is returned:

Jan 17 17:09:46 raptor nrpe[25208]: Return Code: 2,
Output: DISK CRITICAL - free space: /usr 0 MB (0% inode=34%);|
/usr=3717MB;3003;3378;0;3754

Jan 17 17:09:46 raptor nrpe[25217]: Return Code: 2,
Output: NRPE: Command 'check_foo' not defined

This is unfortunate, for example it is not possible to reliably check a
remote NRPE server for which checks it supports, as the return values
for services in critical state would be ommitted.

I think it would make more sense to return the error code (3,
STATE_UNKNOWN) in the case of a non-configured check, or possibly assign
a different error code alltogether for this case..


cheers,

Michael
