=head1 NAME
|
||||||
|
|
||||||
|
du_pattern - plugin to monitor files size selected and grouped by a pattern
|
||||||
|
|
||||||
|
=head1 CONFIGURATION
|
||||||
|
|
||||||
|
[du_pattern]
|
||||||
|
env.DIR /var/log/apache/
|
||||||
|
env.PATTERN www.example.com www.sample.com
|
||||||
|
|
||||||
|
In PATTERN, all items will be expanded like this : www.example.com*
|
||||||
|
In this example, you will monitor the size of :
|
||||||
|
/var/log/apache/www.example.com*
|
||||||
|
/var/log/apache/www.sample.com*
|
||||||
|
|
||||||
|
It's useful if you want to graph the size of your sites' log archives for example,
|
||||||
|
one graph per site.
