# Update the telemetry config of a serving endpoint

Launch stage: GA

`PATCH /api/2.0/serving-endpoints/{name}/telemetry-config`

Updates the telemetry configuration of a serving endpoint.

API scopes: model-serving

## Path parameters

- `name` (string, required)
  The name of the serving endpoint whose telemetry configuration is being updated. This field is required.
  Constraints: `[ 1 .. 63 ] characters`

## Request body

- `telemetry_config` (object, optional)
  The telemetry configuration to be applied to the serving endpoint.
   Can specify either a telemetry_profile_id to use an existing profile,
   or table_names to create a new profile with the specified Unity Catalog tables.
   If not provided, the telemetry configuration will be removed from the endpoint.
  - `telemetry_profile_id` (string, optional, Public Preview)
    The ID of an existing telemetry profile to apply to this endpoint. Provide this to reuse a
     telemetry profile that has already been created, instead of specifying table_names.
  - `table_names` (object, optional, Public Preview)
    The Unity Catalog tables to which endpoint telemetry (logs, traces, and metrics) is exported.
     Provide this to create a new telemetry profile for the endpoint from the given tables.
    - `logs_table` (string, optional, Public Preview)
      The full three-level Unity Catalog name (catalog.schema.table) of the table that receives
       exported logs.
    - `metrics_table` (string, optional, Public Preview)
      The full three-level Unity Catalog name (catalog.schema.table) of the table that receives
       exported metrics.
    - `traces_table` (string, optional, Public Preview)
      The full three-level Unity Catalog name (catalog.schema.table) of the table that receives
       exported traces (spans).
    - `annotations_table` (string, optional, Public Preview)
      The full three-level Unity Catalog name (catalog.schema.table) of the table that receives
       exported annotations.
  - `inference_table_config` (object, optional, Public Preview)
    Configuration for inference table payload logging, including sampling.
    - `sampling_fraction` (double, optional, Public Preview)
      Fraction of requests sampled for payload logging, in the range [0.0, 1.0], where 1.0 logs all requests.
  - `enabled_telemetry_features` (array of string, optional, Public Preview)
    The telemetry signals to enable for this endpoint. If empty or omitted, all signals are
     enabled; otherwise only the listed signals are enabled.
    Possible values:
    - `TELEMETRY_FEATURE_LOGS`
    - `TELEMETRY_FEATURE_TRACES`
    - `TELEMETRY_FEATURE_METRICS`
    - `TELEMETRY_FEATURE_INFERENCE_TABLE`

## Returns

Returns the InferenceEndpointDetailed object.
