We have written a white paper about JMX Interoperation With Non Java Technologies. This whitepaper explains how the Web Services Connector for JMX Agents (defined by JSR 262) was successfully used to provide interoperation with non Java technologies and products such as Hewlett Packard's OpenView Operations Agent (HP-OVO), and Microsoft's Windows Remote Management (WinRM).
Update: Jean-Francois has written an article on how to deploy the JMX WS Connector within a J2EE Application server.[Read More]

And of course, the JMX technology and JConsole graphical tool are part of it. Cherry on the cake: we are even providing NetBeans IDE `projects' that will let you work easily on JMX and JConsole without having to compile the whole OpenJDK![Read More]

A few weeks ago I blogged about how to programmatically access the JVM Monitoring information. Here is a small Java application that prints all the attributes of all the JVM Management & Monitoring MBeans.
The sample simply prints the attributes of the JVM MBeans from the JVM in which it runs. It would be very easy to make it print the information of a remote JVM. You would just need to copy the code from the JVMRuntimeClient shown in my previous blog: [More][Read More]

A few weeks ago, I posted a small example showing
how to programatically retrieve the JVM Management and Monitoring
information. Jeff Mesnil
also recently wrote a two parts blog article showing how to write a JMX client using JRuby.
Piecing these two articles together I'm going to show how to prototype this using JRuby in jconsole Script Shell plugin.

How to use JMX to programatically retrieve the information that JConsole displays is easy. Here is a small JMX Client Program that shows how you can programatically retrieve the JVM Management and Monitoring information from a remote JVM.[Read More]

In this interview Brian goes against a few myths about code optimization, and provides some insightful advices for writing faster code. One of its more striking moto is:
Trust the JVM. It's smarter than you think.

Since JavaTM SE 5.0, the JRE provides a means to manage and monitor the Java Virtual Machine. It comes in two flavors: one is based on the Java Management Extension (JMXTM), the other is a small SNMP agent that builds upon the Management and Monitoring API of the Java SE platform and exposes the same information through SNMP.
Which technology should I use to monitor my JVM? JMX, or SNMP?
In this blog I will try to provide some guidance on this subject.[Read More]

When I created this blog, just one year ago, I was a bit reluctant.
I was afraid that I would rapidly fall short of ideas for articles: instead they keep on piling up... Some of the articles I've been wishing to write may even become obsolete before I find the time to write them ;-).
But most of all, I had absolutely no idea of how much I would enjoy blogging.

This article comes as a follow-up on a series of articles I have written about SNMP. The series starts with [Simple Is Not Easy] and [What is the JVM SNMP Agent?] and continues with [The Hitchhiker's Guide to SNMP - part I], [II], and [III]. Readers who are not familiar with SNMP are invited to browse these articles first.
In Understanding The Structure Of Management Information (SMI), I have already explained how SNMP tables are defined in SMI and introduced the concepts of Scalar Objects and Columnar Objects, Conceptual Rows and Indexes. I have also shown in an example based on the JVM-MANAGEMENT-MIB how to get a columnar object on a simple SNMP table indexed by a single integer.
In this article, I want to explain how all of this works with multi-indexed tables.[Read More]

The JMX forum on SDN is a lively place. Recently, Athahar was trying to expose a POJO resource through JMX - and quite naturally, decided to try out doing this with a ModelMBean. However, ModelMBeans are not the only way to this - and here are a few thoughts, which borrow heavily on some of Eamonn's most recent blog entries.[Read More]
