About

This Nagios plugin checks for available updates using PackageKit http://packagekit.org/ on Linux systems

Why a new plugin?

There are already plugins out there like check_yum and check_apt which do check for updates but they are distribution specific. The main drivers are:

Can run unprivileged, for instance the nrpe user
No sudo/selinux problems
Non distribution specific, works on debian, ubuntu, fedora, centos, rhel...

Usage

Critical Security

Critical on all security type updates

$ check_package_updates --no-longoutput --th "metric=security,critical=1..inf"
Critical - Total: 67, Security: 15, Bug fix: 48, Enhancement: 0, Normal: 4. Critical on security | 'total'=67;;;; 'security'=15;;1..inf;; 'bug fix'=48;;;; 'normal'=4;;;;

Total Updates

Critical on all security type updates and warning on many total updates

$ python check_package_updates --no-longoutput --th "metric=security,critical=1..inf" --th "metric=total,warning=40..inf"
Critical - Total: 67, Security: 15, Bug fix: 48, Enhancement: 0, Normal: 4. Critical on security. Warning on total | 'total'=67;40..inf;;; 'security'=15;;1..inf;; 'bug fix'=48;;;; 'normal'=4;;;;

Long Output

With long output (default) you also get the list of packages

$ python check_package_updates --th "metric=security,critical=1..inf" --th "metric=total,warning=40..inf"
Critical - Total: 32, Security: 1, Bug fix: 31, Enhancement: 0, Normal: 0. Critical on security | 'total'=32;40..inf;;; 'security'=1;;1..inf;; 'bug fix'=31;;;;

Caveats

PackageKit does draw in quite a few packages with it.
Does not work on older distros, like centos/rhel 5.

Dependencies

pynag-0.4.7+
Known to work with PackageKit 0.7.6 or later

Install

Install pynag (available through your favorite package manager)
Install PackageKit (packagekit in Debian)

wget https://raw.github.com/opinkerfi/nagios-plugins/master/check_package_updates/check_package_updates

Room for improvement

The plugin executes pkcon instead of using the API directly. I actually gave the API a whirl via "from gi.repository import PackageKitGlib as packagekit" but the documentation was very lacking so I ended up with pkcon.
