Subject RE: How can I display number of requests over the past n seconds?
Date Thu, 29 Jul 2004 14:16:24 GMT
You would need to modify your filter.  One approach would be to have
separate counters, one for each time period, with a monitor thread for
each one.  The monitor thread would sleep for the duration of the timer,
then reset it.  The Filter would initialize these counters and threads,
then increment each timer by one every time a request comes in.  The JSP
would simply read the counter values.
