Synthetic monitors are API checks or virtual browser instances that monitor your website, recording each check in detail. They can also capture aggregate numbers, including an overview, or summary for ping monitors, detailed statistics for each page resource, and downtime incidents. Synthetic monitoring also collects custom response codes for more detail on your monitor runs.
For a description of synthetic monitor types, see Types of monitor.
There are several types of synthetic monitor to add. Ping monitors ensure your website is responding, while simple browser monitors send real browsers to check your website. For more complex monitoring, scripted browser monitors verify that specific resources are present, while API tests verify your API endpoint.
You can also use the Synthetics REST API to add monitors. For example, you can create a GET request to the monitor you want to use as the source for configuration, then use those key values to use in a POST to "copy" and create a new monitor.
