=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"/>
