MySQL facter

Yesterday I started to play with mcollective

I added some agents like service and facter.

I really liked the facter agent.... and then I decided to add facts for MySQL.
Of course I needed to learn some ruby first :-)

A fact is created for the version and all other MySQL facts come from the SHOW STATUS statement.

All the new facts start by mysql_

I plan to add new facts related to the replication like Seconds_Behind_Master

The current version is available on github here

Some usage examples:

with facter:

[root@delvaux facter]# facter mysql_version 2>/dev/null
5.5.10
[root@delvaux facter]# facter mysql_max_used_connections 2>/dev/null
3

with mcollective:

[root@delvaux facter]# mc-facts mysql_version
Report for fact: mysql_version
