Hi, I have troubles with Performance Explorer while monitoring a IBM Websphere Server through PerfServlet. We can see all performance data from a generated XML file if we call PerfServlet in Internet Explorer, but in Silk Performance Explorer it does not work always... at start, performs a user authentication (PerfServlet cannot work if permission are granted to "everyone", so that we had to say "all authenticated") and the timeout appears. Have someone the same experience ? thanx, it is very unconfortable to work with that problem. Michele
