[Pkg-nagios-devel] Bug#905318: monitoring-plugins-common: $PATH_TO_SUDO is not set (required by check_mailq -s)

[Adam Bolte]

Package: monitoring-plugins-common
Version: 2.2-3
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I have a postfix installation where main.cf is configured like so:

-rw-r----- 1 root root 2013 Aug  3 11:41 /etc/postfix/main.cf

This breaks mailq if executed without sudo, so I have icinga2 call
check_mail (from the monitoring-plugins-standard package) with
-s. This doesn't work since the check_mail script is actually unable
to call the sudo command.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

This fixes the issue:

$ diff /usr/lib/nagios/plugins/utils.pm{.orig,}
20c20
< $PATH_TO_SUDO    = "";
---
> $PATH_TO_SUDO    = "/usr/bin/sudo";

Apparently the build system is supposed to take care of this
automatically.


   * What was the outcome of this action?

$ /usr/lib/nagios/plugins/check_mailq -s -w 4 -c 8 -M postfix -v
mailq: fatal: open /etc/postfix/main.cf: Permission denied
CRITICAL: Error code 75 returned from /usr/bin/mailq


   * What outcome did you expect instead?

$ /usr/lib/nagios/plugins/check_mailq -s -w 4 -c 8 -M postfix -v
OK: postfix mailq reports queue is empty|unsent=0;4;8;0

Hopefully it's a simple fix. Thanks for taking a look.

Regards,
Adam
