Example

In this example, the request updates the Low disk space rule we created in the POST request example. It changes the threshold to 4% in 9 out of 10 samples. It restricts the scope of the alert to the HOST-IG-1 host, which has the Dynatrace entity ID of HOST-DE7EB04EB33F3040.

The API token is passed in the Authorization header.
