=head1 NAME
tomcat_access - Plugin to monitor the number of accesses to Tomcat
servers.
=head1 CONFIGURATION
The following environment variables are used by this plugin
timeout - Connection timeout
url - Override default status-url
ports - HTTP port numbers
pname - Nome of the connector
user - Manager username
password - Manager password
=head1 USAGE
Requirements:
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"/>
