Creating a metric event via APIv2: "No scope generator registered"

CJimenez — Mon, 27 Mar 2023 07:15:52 GMT

Hi,

I have been using the settings API v2 to create anomaly detection for process availability alerts.

I am now trying to apply the same process to create metric event alerts (formerly known and custom events for alerting).

However, I get an error when trying to post to the settings API

https://xxxxx.live.dynatrace.com/e/xxxxx/api/v2/settings/objects?validateOnly=true

[

{

"schemaId": "builtin:anomaly-detection.metric-events",

"value": {

"enabled": true,

xxxxxxxxx

---RESPONSE

"error": {

"code": 404,

"message": "No scope generator registered for schema builtin:anomaly-detection.metric-events"

I'm only guessing, but does that mean there is currently no implementation of the metric-event scope within the settings API v2?

Hi,

Thanks for your response, yes, I get the same when I query the API but does not accept a POST

This works fine:
GET https://{your-domain}.live.dynatrace.com/e/{your-domain}/api/v2/settings/objects?schemaIds=builtin:anomaly-detection.metric-events

However, this returns the error "No scope generator registered for schema builtin:anomaly-detection.metric-events":

POST https://{your-domain} .live.dynatrace.com/e/{your-domain} /api/v2/settings/objects?validateOnly=true

With JSON payload:

"schemaId": "builtin:anomaly-detection.metric-events",
"schemaVersion": "1.0.1",
"value": {
"enabled": true,

Found the issue for those facing similar:

The issue was the missing scope. For other settings that relate to an entity, you need to provide the entity ID as the scope. But in the case of Metric Events, the scope needs to be 'environment' as it does not link to a specific entity.
