Script mode for HTTP monitor configuration

In addition to the usual configuration in the UI, you can use Script mode to configure your HTTP monitors. In this mode, you can access the underlying JSON script of your monitor. If you're a synthetic power user, this will make your life a lot easier and allow you to speed up monitor creation and management. Use the script editor to quickly find specific events (steps), adapt locators across the whole script.

You aren't limited to just one mode—you can switch back and forth between the UI and script modes by clicking the UI Configuration/Script switch.

Access the script

To edit your HTTP monitor in script mode:

  1. Select Synthetic from the navigation menu.
  2. Select the HTTP monitor you want to edit.
  3. Click the Browse (...) button and select Edit.
  4. Click the HTTP Requests tab in the Monitor settings menu on the left.
  5. Click Script at the top.

Edit the script

You can download the script, or just copy it from the editor, and edit it in a text editor of your choice.

However, you can also edit the script directly in the browser. This provides the following benefits:

  • Autocomplete—just press Ctrl+Spacebar to see the list of suggestions.
  • Syntax highlighting makes it easier for you to write script code.
  • Instant error validation—the editor instantly shows a warning for any error in the script. Hover over the error to see what's wrong and a suggestion for how to fix it. You cannot save changes until the code is error free.
