I’m working with a Java Enterprise solution, running 100+ of java applications communicating with each other by RMI/MQ/JMS over MQ/SOAP.
There was a need for getting more information from how the applications «worked inside» and which methods called another application and so on.
Paul Rene Jørgensen and steinar.cook created a application called UseMon which is a monitoring system for trends , response time and dependency analysis of plain Java applications or big multi-clustered Java Enterprise applications running in production.
Usemon loggs the monitoring data to a MySQL database in our environment.
I then created a php-solution which fetches data from the database (by reading the Usemon v1.0 Database Schema.pdf document.)
I’ve so far created a page which analyze the communication in the applications and creates a dot-language graph which then is exported to a png by using GraphViz .
Here is a result for calls running a couple of seconds.
Here you can see the applications with it’s methods inside the «application-box» and how they call each others and other methods in other applications.
I have a lot to do at work now, so it may be a little while before I can continue on this application.
