scope and presenting realtime data

[ra...@nmsworks.co.in]

Hi,

We are developing a web based interface (struts + jsp etc) for realtime 
monitoring of server cpu usage.

We have written a bean that will contact the server and get the current
cpu usage and return that value. I want to plot a line graph (using
jfreechart) with the cpu usage in Y-axis and time in X-axis.  The Graph
need to plot the last 'N' values + the current value during each refresh.

The issue is how to remember these last N values. I do not want to assign 
session scope for this object as the end-user might monitor for more than 
one servers and several users might be using the system at same time.

How this situation is typically handled in the Struts+jsp environment.

thanks & regards
  -Ramudu
