Similar to Time Watcher, Network Watcher allows measuring load time of network elements during the execution of a certain range of steps within a monitoring script, grouped by type (set a mask, like *.png, *.js, etc.).

To enable Network Watcher:

  1. Right-click the line (step), after which Network Watcher should start measures.
  2. Select Network Watcher.
  3. If necessary adjust name, type, threshold, and mask for measurement.
  4. Select a type to define how to apply threshold value:
    • Sum – apply the threshold to the sum of load times of all requests.
    • Average – apply the threshold to the arithmetic average of all requests.
    • Each – apply the threshold to each request.
  5. Right-click the line, after which measurement must be stopped, select Close Watcher, and choose the name of the watcher to close.

Image URLs has the next format:

In this case URL mask for Watcher have to be:
