Example

In this example, the request updates the configuration of anomaly detection for database services from the GET request example. It activates the Alert on graceful host shutdowns feature. It also changes Detect CPU saturation on host mode to based on custom settings and sets the following threshold:

Alert if CPU usage is higher than 90% in 3 out of 5 samples.

The API token is passed in the Authorization header.

You can download or copy the example request body to try it out on your own. First, be sure to create a backup copy of your current configuration with the GET host anomaly detection configuration call.
