Performance Intelligence Dashboards
CloudTest provides System “performance intelligence” dashboards--such as Combined Charts, Correlated Charts, Waterfall Dashboard, and many others. These appear i the New or Existing Dashboard box, System Dashboard list when creating a dashboard, and are located in Central > Library in:
/System Objects/Dashboards/Performance Intelligence
These dashboards increase performance intelligence by helping you identify common testing issues—such as the “classic bottleneck.”
Within a classic bottleneck, as Virtual Users go up the message Send Rate to the target web site also goes up. Eventually, this flattens out, as response times back up and more queues (on the test site) are filled. This leads to increased errors (connection timeouts and resets) because the queue is too full and things are falling off of it. On a chart, this looks rather like a hose that is kinked.
