Datadog metric tag configuration must support providing no tags for distribution type metrics

[rymir]

Terraform Version

Terraform v1.2.7

provider registry.terraform.io/datadog/datadog v3.13.1

Affected Resource(s)

• datadog_metric_tag_configuration

Terraform Configuration Files

resource "datadog_metric_tag_configuration" "linkerd_response_latency" {
  metric_name         = "linkerd.response_latency"
  metric_type         = "distribution"
  include_percentiles = true
  tags = []
}

Expected Behavior

Would expect the ability to not provide any tags (omit the field) when configuring datadog distribution metrics, as datadog distribution metrics do not support managing tags and their endpoint fails when including the field.

Actual Behavior

When omitting the tags field, the provider fails with Error: Missing required argument.

When providing an empty list of tags, the provider fails with:

│ Error: error creating MetricTagConfiguration from https://api.datadoghq.com/api/v2/metrics/linkerd.response_latency/tags: 400 Bad Request: {"errors":["Cannot configure tags on metric because metric is an integration metric: linkerd.response_latency."]}

[NasAmin]

Sadly, it is a required field in the underlying API :(

If there was a different way of setting percentiles on a metric without the tag config then it would have been better.

The API seems a bit bloated as its putting it all under "tag configuration"

Any update on this?

Still the case almost 2 years later:
