Basic Capacity Monitor

On shared production servers where 20 to 40 application servers (JVMs) are running a Websphere® application server, if there is problem it is difficult to know which application is causing problem.

This invention gives live information about J2EE app configured in Websphere application server. It displays numbers of web container threads, the health of HTTP servers, free JVM information, and CPU health in a browser. This data is refreshed every 60 seconds.

It gives clear information on which web container is causing the problem. Once the problem is found, it performs actions such as taking 3

javacores in intervals of three

minutes when a certain threshold is reached on any web container and then that JVM is recycled. Once javacores are taken, an email alert is sent to server administrator.

The Basic Capacity Monitoring (BCMon) tool is made using PERL script. This tool first executes a JACL script to gather Websphere configuration information and PERL script uses this to render a run time HTML page. Typically, the HTML page is generated in a document root path of the HTTP server.

This invention easily saves labor hours. It gives minimum down time for applications. Also it records proof of problem or root cause of problem in javacore.
