=head1 NAME
apache_average_request - Munin plugin to monitor the average request to
Apache servers. It handles a list of ports passed in from a plugin
configuration file.
=head1 APPLICABLE SYSTEMS
Apache HTTP servers with C</server-status> enabled.
=head1 CONFIGURATION
Enable stats in apache first!:
<VirtualHost 127.0.0.1:80>
<Location /server-status>
SetHandler server-status
AuthUserFile /route/to/auth.file
AuthName Login-Stats
AuthType Basic
require valid-user
</Location>
</VirtualHost>
And now in munin conf:
[apache_*]
env.url http://USER:PASS@127.0.0.1/server-status?auto
env.ports 80
