Announce: Check_Yum for RedHat/CentOS server package alerts

[Hari Sekhon]

Hi,

   I've just released the Check_Yum plugin on NagiosExchange.org as the 
only one there seemed quite inadequate.

Features of the new plugin (none of which are in the old plugin) include:

- Differentiate between Security / normal package updates
- Better output - numbers of packages updates
- Support for extra Yum options including enabling and disabling repos, 
running from the cache
- Optional Warning on non-security updates
- Optional Critical alerting on any package
- Timeout
- Verbosity
- Less false package alerts (the old plugin just used to misleading say 
the O/S needed updates when yum failed for any reason at all), including 
proper error feedback and a switch for lock handling to not raise an 
alert like if somebody is running yum interactively at the same time.


You can download the plugin here:

(you may need to copy and paste that link if your mail client 
misinterprets the link)

As ever, feedback is welcome, and development will continue if needed 
for extra switches and features.
This should also work with Fedora or another RPM based distros that uses 
yum as it's package management system but I've not tested it outside 
RHEL/CentOS so feedback is welcome there too.


On a related note, I'm also quite interested in people's experiences of 
updating and maintaining RedHat based systems especially with regards to 
security. I spoke to a few people and they basically don't follow 
security vulnerabilities and don't patch which ties in with my 
experiences and what I've seen of other people's systems too which is 
very disappointing. Hopefully this will make it easier to automatically 
track and keep on top of security updates for those of us who have 
RedHat Enterprise Linux 5 or later or equivalent.


Thanks
