+# Collectmetrics - Get Custom
+
+Captures metrics for a process, with the ability to specify custom metrics.
+
+## HTTP Route
+
+```http
+POST /collectmetrics?pid={pid}&uid={uid}&name={name}&metricsIntervalSeconds={metricsIntervalSeconds}&durationSeconds={durationSeconds}&egressProvider={egressProvider} HTTP/1.1
+```
+
+> **NOTE:** Process information (IDs, names, environment, etc) may change between invocations of these APIs. Processes may start or stop between API invocations, causing this information to change.
+
+## Host Address
+
+The default host address for these routes is `https://localhost:52323`. This route is only available on the addresses configured via the `--urls` command line parameter and the `DOTNETMONITOR_URLS` environment variable.
+
+## URI Parameters
+
+| Name | In | Required | Type | Description |
+|---|---|---|---|---|
+| `pid` | query | false | int | The ID of the process. |
+| `uid` | query | false | guid | A value that uniquely identifies a runtime instance within a process. |
+| `name` | query | false | string | The name of the process. |
+| `metricsIntervalSeconds` | query | false | int | The time interval used to collect metrics. Default is 5. |
+| `durationSeconds` | query | false | int | The duration of the metrics operation in seconds. Default is `30`. Min is `-1` (indefinite duration). Max is `2147483647`. |
+| `egressProvider` | query | false | string | If specified, uses the named egress provider for egressing the collected metrics. When not specified, the metrics are written to the HTTP response stream. See [Egress Providers](../egress.md) for more details. |
+
+See [ProcessIdentifier](definitions.md#ProcessIdentifier) for more details about the `pid`, `uid`, and `name` parameters.
+
+If none of `pid`, `uid`, or `name` are specified, artifacts for the [default process](defaultprocess.md) will be captured. Attempting to capture artifacts of the default process when the default process cannot be resolved will fail.
+
+## Authentication
+
+Authentication is enforced for this route. See [Authentication](./../authentication.md) for further information.
+
+Allowed schemes:
+- `Bearer`
+- `Negotiate` (Windows only, running as unelevated)
+
+## Request Body
+
+A request body of type [EventMetricsConfiguration](definitions.md#EventMetricsConfiguration) is required.
+
+The expected content type is `application/json`.
+
+## Responses
+
+| Name | Type | Description | Content Type |
+|---|---|---|---|
+| 200 OK | [Metric](./definitions.md/#Metric) | The metrics from the process formatted as json sequence. Each JSON object is a [metrics object](./definitions.md/#Metric)| `application/json-seq` |
+| 202 Accepted | | When an egress provider is specified, the Location header containers the URI of the operation for querying the egress status. | |
+| 400 Bad Request | [ValidationProblemDetails](definitions.md#ValidationProblemDetails) | An error occurred due to invalid input. The response body describes the specific problem(s). | `application/problem+json` |
+| 401 Unauthorized | | Authentication is required to complete the request. See [Authentication](./../authentication.md) for further information. | |
+| 429 Too Many Requests | | There are too many requests at this time. Try to request metrics at a later time. | `application/problem+json` |
