Monitor Charts and Monitor Writers

Performance Explorer provides monitor charts and monitor reports to display and store measured values.
  • A monitor chart displays the measured values of a data source in real-time. You can adjust the polling interval of a monitor chart.
  • A monitor writer records the measured values of a data source and stores them in a .tsd file. Monitor writers are also useful to compare server-side and client-side measures when a load test is completed.
Note: A short polling interval can reduce the performance of your computer which, consequently, can influence test results. For large load tests, define intervals greater than 60 seconds.
Note: The values that display in a monitor chart cannot be written to a .tsd file afterwards.
