Happy new year, everyone:
I have a question and hope you guys can help me.
Our software group are implementing a j2ee application. We want to have a system monitor to monitor stuffs like the number of users logged in.
The system should be monitored using chart. We want the chart to be dynamically updated in a fixed period of time, or by clicking refresh button. I searched on the web, there are lots of chart products implemented in applet. As I heard, applet has problems with IE. Have somebody ever used some chart products to achieve the similar purpose? Could you recommend some chart product to me? I really appreciated your help and suggestions.
Thank you very much.
Regards

We use BMP Patrol which monitors concurrent users, load, CPU usage, etc.
Lovely charts and such.

Well that could be because I spelled it wrong :roll: .
BMC Patrol
And also, javaquestion king,

Please change your name to be compliant with JavaRanch's naming policy.
Your displayed name should be 2 separate names with more than 1 letter each. It should not be an obviously fictitious name. We really would prefer that you use your REAL name.
You can change your name: here.
Thanks,

Good point. The J2ee application that I am just now inheriting uses JMX. I am not personally very familiar with it ( yet )
The applications that we have that use BMC Patrol have Java front ends with a Corba interface to c++ server side. Since the Oracle interaction is all on the server side, that is where most of the monitoring is done.
 
It is sorta covered in the JavaRanch Style Guide.
