JMX Query Tool

Table of Contents

A monitoring tool

If you run some java stuff, you might want to monitor some specific things going on. The scripts on this page permit you to get informations relative to Java running on a server by using Jmx4Perl. It is however required that the corresponding servlet is installed on the server for this to work.

The latest version of the script can be loaded from the current UseLocalActiveMQForMessaging project SVN specified on the page in the monitoring directory. Should this no longer be the case, the scripts are also attached to this page, but they will not be updated.

Jmx4Perl module and Servlet

You will find the necessary files for module and servlet installation here : http://search.cpan.org/~roland/jmx4perl/ .

jmx-query.pl

This perl script will query the specified bean on the specified server and return the value of a specified attribute.

• Usage : ./jmx-query.pl server bean attribute
• Example : ./jmx-query.pl "http://myJeeServer:port/j4p" "org.apache.activemq:BrokerName=lxbrf2711.cern.ch,Type=Broker" TotalDequeueCount

The script simply outputs the value, without any formatting.

jmx-multi-query.pl
