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.

Let’s assume we have an online store that relies on CDN where some of the portal images are placed. We wanna measure is this particular CDN satisfies our claims to a speed of load.

All we need is to add Network Watcher configured to measure the load time of images for this CDN.

Image URLs has the next format:

http://1ba0.cdndomain.com/abc/1234567/image_1.png
http://f4d4.cdndomain.net/kh3/1234567/image_2.png

In this case URL mask for Watcher have to be:

*.cdndomain.*.png
