JavaOne 2008 : Monitoring Your Enterprise Easily
posted Thursday, 8 May 2008
 | Jennifer. One of the most interesting applications at JavaOne 2008 is Jennifer. I had never heard of them before and I walked by the booth and was really surprised by the elegant GUI design and by the nice way it solves a bunch of enterprise problems. Jennifer performs provides a real-time monitoring dashboard of web servers, user visits, response times, | app servers, even non-Java apps, Oracle database performance, system CPU, memory, disk & network usage, processing associated with backend transactions and business data. The monitoring also reports on numbers of concurrent users, visitors per day/hour, currently active services, actgive JDBC connection assignments & status, response time graphs, JDBC/SQL monitoring, app response times, opened TCP/IP sockets by application and much, much more - including connecting into CTG, WTC, Jolt, J*Link, TUXEDO and CICS. | For me, this was one of the most useful discoveries at JavaOne. I deal with companies with large numbers of servers (app, web, database, etc) - this solves the problem of being able to see what's happening to groups of servers and within individual servers. Jennifer also has nice 2D and 3D visualization (with different color cues) - you can see one of the screenshots at right. Jennifer-3D is designed to be displayed on a large monitor in a datacenter's monitoring area. You can find more information on Jennifer here. |
