Hi,

Some time back I developed a tool for a friend to monitor Jboss cluster state and send alert mails when there’s a change in cluster view. I am sharing it because someone might find it useful and they can add some more functionality to it. If you do please let me know.

You can deploy it as a windows service and if you need to change anything, you only need to change parameters in configuration file… run update script and you are done.

Here are the details and usage Guide

1. What It Does?

Monitor jboss clusters at an interval of 1 min (this can be changed) and send mail alerts if cluster view changes i.e. some nodes not responding, nodes getting removed from cluster or new node getting added.

It will keep sending the alerts untill the problem is resolved or service is stopped.

2. How to install service?

Install-JbossClusterMonitor.bat

3. How to uninstall service?

Uninstall-JbossClusterMonitor.bat

4. How to start,stop service?

JbossClusterMonitorStart.bat and JbossClusterMonitorStop.bat respectively or from command prompt
NET STOP JbossClusterMonitor and NET START JbossClusterMonitor

5. How to change service name?

Open wrapper.conf and replace all occurrence of JbossClusterMonitor with name you want. Also replace same in start/stop scripts. Change script names.

6. Steps to change anything related to mail sending like smtp ip/port, to and from address, add/remove cluster/nodes to monitor or monitoring interval.

a. Stop service.
b. Edit “/conf/jbossClusterMonitor.properties” file to change the required setting.
c. Run updateJar.bat
d. Start service.

You need to set all the parameters in “/conf/jbossClusterMonitor.properties” file before the first use and make sure you have JAVA_HOME and JBOSS_HOME set.

You can download it from here
