Returns 200 with `kind=exemption` when an explicit exemption exists, 200 with `kind=legacy_tag_configuration` when the metric has a legacy tag configuration acting as an implicit exclusion, or 404 when neither applies. This endpoint requires the `metrics_read` permission. OAuth apps require the `metrics_read` authorization [scope](https://dnd37xeb23o8n.cloudfront.net/jen.gilbert/astro-base/ja/api/latest/scopes.md#metrics) to access this endpoint. ### Arguments #### Path Parameters | Field | Type | Description | | ------------------------ | ------ | ----------------------- | | metric_name [*required*] | string | The name of the metric. | ### Response {% tabs %} {% tab label="200" %} OK {% tabs %} {% tab label="Model" %} Response containing a tag indexing rule exemption. | Parent field | Field | Type | Description | | ------------ | -------------------------- | --------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | data | object | A tag indexing rule exemption resource object. | | data | attributes | object | Attributes of a tag indexing rule exemption. | | attributes | created_at | date-time | Timestamp when the exemption was created. Read-only. | | attributes | created_by_handle | string | Handle of the user who created the exemption. Read-only. | | attributes | estimated_change_in_volume | int64 | Estimated change in indexed cardinality or points if the exemption is removed and the matching tag indexing rule applies to the metric. A negative value indicates a reduction in indexed volume, a positive value indicates an increase, and zero indicates no change. A `null` value indicates that the estimate is unavailable. Read-only. | | attributes | kind | string | Discriminates between an explicit exemption (`exemption`) and a pre-existing legacy tag configuration acting as an implicit exclusion (`legacy_tag_configuration`). | | attributes | missing_indexed_tags | [string] | Tag keys used to query this metric in monitors, dashboards, notebooks, and SLOs that the matching rule would remove or not include if the exemption is removed. Read-only. | | attributes | reason | string | The reason the metric is exempt from tag indexing rules. | | attributes | volume_status | enum | Indicates whether `estimated_change_in_volume` is available and, if not, why. `ok` indicates a fresh estimate. `unindexed_tags` indicates that the matching rule uses tags that are not indexed for the metric. `unavailable` indicates that the estimate is stale, was not computed, or could not be retrieved. Read-only. Allowed enum values: `ok`, `unindexed_tags`, `unavailable`. | | data | id | string | The metric name, used as the resource ID. | | data | type | enum | The tag indexing rule exemption resource type. Allowed enum values: `tag_indexing_rule_exemptions`. Default: `tag_indexing_rule_exemptions`. | {% /tab %} {% tab label="Example" %} ```json { "data": { "attributes": { "created_at": "2024-01-15T12:00:00.000Z", "created_by_handle": "user@datadoghq.com",
