+
+The New Relic Log plugin enables pushing logs to New Relic.
+
+<EnterpriseFeature name="Custom logging" />
+
+## Setup
+
+To add the New Relic logging plugin to your Zuplo project, add the following
+code to your `zuplo.runtime.ts` file. Set the `url` parameter (optional) to the
+value of your New Relic log API endpoint and the `NEW_RELIC_API_KEY` environment
+variable to your New Relic API key.
+
+Any custom fields you want to include in the log entry can be added to the
+`fields` property. These values will be appended to every log entry.
+
+```ts title="modules/zuplo.runtime.ts"
+import {
+  RuntimeExtensions,
+  NewRelicLoggingPlugin,
+  environment,
+} from "@zuplo/runtime";
+
+export function runtimeInit(runtime: RuntimeExtensions) {
+  runtime.addPlugin(
+    new NewRelicLoggingPlugin({
+      // Optional, defaults to "https://log-api.newrelic.com/log/v1"
+      url: "https://log-api.newrelic.com/log/v1",
+      apiKey: environment.NEW_RELIC_API_KEY,
+      service: "MyAPI", // Optional, defaults to "Zuplo"
+      fields: {
+        field1: "value1",
+        field2: "value2",
+      },
+    }),
+  );
+}
+```
+
+## Standard Fields
+
+Every log entry will include the following fields:
+
+- `message` - The log message and data
+- `level` - The level of the log, for example `error`, `info`, etc.
+- `timestamp` - The time the log was created (in milliseconds since epoch)
+- `service` - The name of the service (defaults to "Zuplo" or custom value
+  provided)
+- `environment` - The deployment name of the Zuplo API
+- `environment_type` - Where the Zuplo API is running. Values are `edge`,
+  `working-copy`, or `local`
+- `environment_stage` - If the environment is `working-copy`, `preview`, or
+  `production`
+- `request_id` - The UUID of the request (the value of the `zp-rid` header)
+- `atomic_counter` - An atomic number that's used to order logs that have the
+  same timestamp
+- `ray_id` - The network provider identifier (i.e. Cloudflare RayID) of the
+  request
+- `log_source` - The source of the log entry

+### New Relic (Beta)
+
+By default, we send all metrics to New Relic. However, you have the option below
+to configure which metrics you want to send.
+
+New Relic's Metric API provides a powerful way to monitor your API's performance. The metrics are sent to New Relic's Metric API endpoint (https://metric-api.newrelic.com/metric/v1) by default, but you can customize this if needed.
+
+```ts
+import {
+  RuntimeExtensions,
+  NewRelicMetricsPlugin,
+  environment,
+} from "@zuplo/runtime";
+
+export function runtimeInit(runtime: RuntimeExtensions) {
+  runtime.addPlugin(
+    new NewRelicMetricsPlugin({
+      apiKey: environment.NEW_RELIC_API_KEY,
+      // Optional: customize the URL if needed
+      // url: "https://metric-api.newrelic.com/metric/v1",
+      // You can add custom attributes to all metrics
+      attributes: {
+        service: "my-service-name",
+        environment: environment.ENVIRONMENT ?? "DEVELOPMENT",
+      },
+      metrics: {
+        latency: true,
+        requestContentLength: true,
+        responseContentLength: true,
+      },
+      // You can also choose to add additional attributes to include in the metrics
+      include: {
+        country: false,
+        httpMethod: false,
+        statusCode: false,
+        path: false,
+      },
+    }),
+  );
+}
+```
+
+The above configuration applies globally for all metrics sent to New Relic. If you
+wish to dynamically configure information for a particular ZuploContext, you can
+use the `NewRelicMetricsPlugin` in your code. Currently, the only configuration
+you can set is the attributes. The values you set here will be appended to those set
+globally in the `zuplo.runtime.ts` file.
+
+```ts
+import {
+  ZuploContext,
+  ZuploRequest,
+  NewRelicMetricsPlugin,
+} from "@zuplo/runtime";
+
+export default async function (request: ZuploRequest, context: ZuploContext) {
+  const someValue = "hello";
+  NewRelicMetricsPlugin.setContext(context, {
+    attributes: { "my-custom-attribute": someValue },
+  });
+
+  return "What zup?";
+}
+```
