=head1 NAME
tomcat_volume - Plugin to monitor the volume of data sent from Tomcat
servers.
=head1 CONFIGURATION
The following environment variables are used by this plugin
=over 4
=item timeout
Connection timeout
=item url
Override default status-url
=item ports
HTTP port numbers
=item user
Manager username
=item password
Manager password
=back
=head2 CONFIGURATION EXAMPLE
[tomcat_volume]
env.ports 8081
env.user someuser
env.password somepassword
=head1 AUTHOR
Rune Nordbøe Skillingstad <runesk@linpro.no>
=head1 USAGE
Needs access to
http://<user>:<password>@localhost:8080/manager/status?XML=true (or
modify the address for another host).
Tomcat 5.0 or higher.
A munin-user in $CATALINA_HOME/conf/tomcat-users.xml should be set up
for this to work.
Tip: To see if it's already set up correctly, just run this plugin
with the parameter "autoconf". If you get a "yes", everything should
work like a charm already.
tomcat-users.xml example:
<user username="munin" password="<set this>"
roles="standard,manager"/>
