Nagios ssh proxy apt check not working correctly

[scottwilkerson]

I think I see the problem, you are assuming that check_apt is going to give you what you get when you login.

It is not designed to do that, you specific which items you want to match as critical, per the help:

Code: Select all

-c, --critical=REGEXP
        If the full package information of any of the upgradable packages match
        this REGEXP, the plugin will return CRITICAL status.  Can be specified
        multiple times like above.  Default is a regexp matching security
        upgrades for Debian and Ubuntu:
        	^[^\(]*\(.* (Debian-Security:|Ubuntu:[^/]*/[^-]*-security)
        Note that the package must first match the include list before its
        information is compared against the critical list.

These are what are going to me barked critical, not the security updates listed when you login, that is something different entirely.

You could create a plugin that does something like that, and use that instead if you like
