=head1 NAME
|
|
|
|
Wordpress-Multisite Munin Plugin
|
|
|
|
A Munin plugin to monitor posts, comments and pingbacks from every multisite instance.
|
|
It uses multigraphs and also shows the combined number of posts, comments, pingbacks, instances and users.
|
|
|
|
Most database queries came from the wordpress-mu-plugin which was written by Andre Darafarin and Chris Bair
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
The plugin need access to the wordpress database
|
|
|
|
=head2 Config file
|
|
|
|
Create the config file plugin-conf.d/wordpress with the following values:
|
|
|
|
[wordpress*]
|
|
env.mysqlopts # I.e. -uroot -prootpass
|
|
env.mysqlconnection # Defaults to -hlocalhost
|
|
env.database # I.e. wordpress
|
|
env.dbprefix # Defaults to wp_
|
|
env.networksize # Blogs are ordered by id in multigraph view. This value should contain the numbers
|
|
# of digits that are needed to fit all the blog id's in. This value influences the
|
|
# designation of data to munin and it will start collecting fresh data if you change
|
|
# this number. Defaults to 2, (so networks with <= 99 blogs will be sorted correctly)
|
