[Pkg-nagios-devel] Bug#445976: nagios-nrpe-plugin: Return STATE_UNKNOWN when nrpe cannot communicate with nrpe_server

[Michael Bussmann]

Package: nagios-nrpe-plugin
Version: 2.8.1-1
Severity: wishlist
Tags: patch

Hi,

While check_nrpe has a "-u" option to return STATE_UNKNOWN (instead of
STATE_CRIT) when a socket timeout occurs, it sometimes still returns
STATE_CRIT, when there are errors in opening the connection in
my_connect().

As we don't know anything about the result of the checks if the host cannot
be reached, I think it's better to return STATE_UNKNOWN instead of
STATE_CRITITCAL.

Another option would be to return timeout_return_code (thus honoring
-u).

Cheers,
MB
