Dynatrace dimension length constraint not honored

Hi,

We are enabling Dynatrace Register for micrometer. Below is the output we get. It seems like the URI is too long for the dimension accepted in Dynatrace. Any suggested workarounds for this?

2020-11-05 14:02:09.920 lvl=ERROR : failed to send metrics to dynatrace: { "error": { "code": 400, "message": "Constraints violated.", "constraintViolations": [ { "path": "series[68].dimensions.uri", "message": "Value exceeds maximum length.Maximum value length: 128 (inclusively).", "parameterLocation": "PAYLOAD_BODY", "location": null }, { "path": "series[70].dimensions.uri", "message": "Value exceeds maximum length.Maximum value length: 128 (inclusively).", "parameterLocation": "PAYLOAD_BODY", "location": null }, { "path": "series[69].dimensions.uri", "message": "Value exceeds maximum length.Maximum value length: 128 (inclusively).", "parameterLocation": "PAYLOAD_BODY", "location": null }, { "path": "series[67].dimensions.uri", "message": "Value exceeds maximum length.Maximum value length: 128 (inclusively).", "parameterLocation": "PAYLOAD_BODY", "location": null } ] } }

Hi @jonatan-ivanov, I implemented a fix for this (see #2575).

I reached out to the Dynatrace OSS Team, here’s their answer:

It is a hardcoded limit of 128 for the length of a dimension value, so the message in the error response from the API is correct. The limit is not configurable. In this case, truncating would make sense.
