I've been using the jmx-console to check on the ManagedConnectionPool's and the jboss.system - ServerInfo to look at memory and threads. I'd be interested in finding any other key indicators.

Also, I went over to sourceforge to look for monitoring tools and found something called EJTools which seems to work ok with JBoss 3.2.x to examine the same sort of info. It'd be nice to know if anyone else is using this and what for.

What I was really hoping to find was a tool that could be configured to monitor various key indicators and send an alarm/page/email when various threshholds were exceeded.

I believe JBoss WebConsole can do what you want, gshifrin.

You access it at the URL :
http://hostname/web-console

More info here :
http://jboss.org/wiki/Wiki.jsp?page=WebConsole

By the way, i'm also very interested into relevant MBeans to monitor :
for now I just monitor FreeMemory and ActiveThreadCount
There are just too many MBeans to manually search amongst the other trees.
Does anyone has a fair idea on this subject ?

Thanks in advance.

What you reallly want to watch for are things like CPU and memory usage, free disk space, etc., which can be monitored outside of the JVM. The thread count is important as well as the number of messages for JMS.

Memory usage can be obtained from the MBean

jboss.system:type=ServerInfo

U can view the detail using the below link after replacing jbosshost and port

http://jbosshost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jboss.system%3Atype%3DServerInfo

You can also get ActiveThreadCount from the above MBean

Similarly JDBC stats details can be viewed from the MBean

jboss.jca:name=<JDBC POOL NAME>,service=ManagedConnectionPool

The attribute InUseConnectionCount will give u the exact number connections in use.

Servlet invocation counts can be obtained from
*:j2eeType=Servlet,* MBeans

CPU usage and Disk usage are not exposed through defualt MBeans available in JBoss

To monitor CPU Usage and Disk usage you can use Applications Manager.
It helps you in monitoring performance, availability, and usage statistics of JBoss Servers.

For more info refer
http://manageengine.adventnet.com/products/applications_manager/monitoring-jboss.html

The product is free to monitor upto 10 JBoss servers.
Online demo of the product is available in

Thanks you very much for you help. I searched through the JMX and couldn't find this number of messages you're talking about. Maybe I searched the wrong place ?

Number of messages in the JMS Queue can be obtained from MBean
jboss.mq.destination:service=Queue,name=<QUEUE NAME>.

The attribute QueueDepth in the MBean gives the number of messages currently in the queue.

The operation listMessages will list all the messages in the queue.

All these parameters can be monitored using Applications Manager6.0.

The product can be downloaded from http://manageengine.adventnet.com/products/applications_manager/download.html

Thanks for your help. About your software, does the free version include MBean monitoring ?

The Free Edition never expires and you get all functionality of the Professional Edition.

Installing Applications Manager Free Edition allows you to monitor and manage 5 monitors in your network.

Thanks
