check_tomcat (plugin for Nagios)

The 'check_tomcat' script is designed to monitor Apache Tomcat through JMX Proxy Servlet in combination with 'check_by_ssh' plugin. The first step is to ensure that the central Nagios server is able to connect to the remote host via SSH in a manner that does not require a password. The second step is to ensure that the user executing 'check_tomcat' plugin has read permissions on "${CATALINA_BASE}/conf/tomcat-users.xml" file. Finally, to access JMX proxy interface requires at least one user with the role manager-jmx and whose password is not encrypted.

The 'check_tomcat' script has four different check types and each monitors the following metrics:

· apps: activeSessions
· memory: HeapMemoryUsage, NonHeapMemoryUsage
· pools: numActive
· threads: currentThreadsBusy

Check types 'memory' and 'threads' return performance data in their output (others return null).

This plugin has been tested with Apache Tomcat 6.x and 7.x (forward compatibility not guaranteed).
