Subject Re: Performance monitoring for web applications
Date Sat, 09 Sep 2006 15:14:12 GMT
Rethinking my previous reply I now think what you want is possible,
even hard to achive. But if you measure the time spent in each
application in an amount of time you will get relative CPU usage for
those webapps; now measuring the cpu time for the VM in the same
amount of time (for example by executing ps via Runtime.exec()) you
can recalculate your relative values to absolute values. Don't know
how accurate it will be. Reading /proc/stat for the jvm process would
be probably more accurate.
