|
|
|
|
nn_ - Munin plugin to display misc newznab stats.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
This script is used to generate data for several graphs. To generate
|
|
data for one specific graph, you need to create a symbolic link with a
|
|
name like nn_<GRAPH> to this script.
|
|
|
|
To get a graph over numbers of users use nn_users
|
|
=head1 APPLICABLE SYSTEMS
|
|
|
|
Any MySQL platform, tested by the author on MySQL 5.1.29 and 5.0.51
