Open Source Application Management Software

We needed a simple application mangement tool for monitoring our Java applications running on Tomcat servers. My team evaluated the various free/open-source options and gave a demo of the following 2 tools that proved to be interesting.

1. ManageEngine Applications Manager - This is free for use (upto 5 monitors). Very user friendly and professional look and feel.

2. JManage - (open source. Good support for Java console applications)
