=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:
|
