Validate payload

We recommend that you validate the payload before submitting it with an actual request. A response code of 204 indicates a valid payload.

The request consumes an application/json payload.

POST	Managed	`https://{your-domain}/e/{your-environment-id}/api/config/v1/anomalyDetection/metricEvents/{id}/validator`
	SaaS	`https://{your-environment-id}.live.dynatrace.com/api/config/v1/anomalyDetection/metricEvents/{id}/validator`
	Environment ActiveGate	`https://{your-activegate-domain}/e/{your-environment-id}/api/config/v1/anomalyDetection/metricEvents/{id}/validator`

Authentication

To execute this request, you need an access token with Write configuration (WriteConfig) scope. To learn how to obtain and use it, see Tokens and authentication.

Response

Code	Type	Description
204		Validated. The submitted configuration is valid. Response doesn't have a body.
400	ErrorEnvelope	Failed. The input is invalid.

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.
