## Documentation content

Use the endpoints described below to manage service health. Service health tracks metrics about a deployment's ability to respond to prediction requests quickly and reliably. This helps identify bottlenecks and assess capacity, which is critical to proper provisioning.

## Retrieve service health metrics by deployment ID

Operation path: `GET /api/v2/deployments/{deploymentId}/batchServiceStats/`

Authentication requirements: `BearerAuth`

Retrieve all deployment service health metrics over a set of batches.

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| executionTimeQuantile | query | number | false | Quantile for executionTime metric. |
| responseTimeQuantile | query | number | false | Quantile for responseTime metric. |
| slowRequestsThreshold | query | integer | false | Threshold for slowRequests metric. |
| segmentAttribute | query | string | false | The name of a segment attribute used for segment analysis. |
| segmentValue | query | string,null | false | The value of the segmentAttribute to segment on. |
| batchId | query | any | false | The id of the batch for which metrics are being retrieved. |
| modelId | query | string | false | The id of the model for which metrics are being retrieved. |
| deploymentId | path | string | true | Unique identifier of the deployment. |

### Enumerated Values

| Parameter | Value |

## Retrieve service health metric over time by deployment ID

Operation path: `GET /api/v2/deployments/{deploymentId}/serviceStatsOverTime/`

Authentication requirements: `BearerAuth`

Retrieve values for one single deployment service health metric over time.

### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| start | query | string,null(date-time) | false | Start of the period to retrieve monitoring data, defaults to 7 days ago from the end of the period. Note: this field only accepts top of the hour RFC3339 datetime strings, for example: 2019-08-01T00:00:00Z. |
| end | query | string,null(date-time) | false | End of the period to retrieve monitoring data, defaults to the next top of the hour. Note: this field only accepts top of the hour RFC3339 datetime strings, for example: 2019-08-01T00:00:00Z. |
| bucketSize | query | string(duration) | false | The time duration of a bucket. Needs to be multiple of one hour. Can not be longer than the total length of the period. If not set, a default value will be calculated based on the start and end time. |
| segmentAttribute | query | string | false | The name of a segment attribute used for segment analysis. |
| segmentValue | query | string,null | false | The value of the segmentAttribute to segment on. |
| modelId | query | any | false | The ID of the models for which metrics are being retrieved. |
| metric | query | string | false | Name of the metric. See below for a list of supported metrics. |
| quantile | query | number | false | A quantile for resulting data, used if metric is executionTime or responseTime, defaults to 0.5. |
| threshold | query | integer | false | A threshold for filtering results, used if metric is slowQueries, defaults to 1000. |
| deploymentId | path | string | true | Unique identifier of the deployment. |

### Enumerated Values

| Parameter | Value |
| --- | --- |
| segmentAttribute | [DataRobot-Consumer, DataRobot-Remote-IP, DataRobot-Host-IP] |
| metric | [totalPredictions, totalRequests, slowRequests, executionTime, responseTime, userErrorRate, serverErrorRate, numConsumers, cacheHitRatio, medianLoad, peakLoad] |
