# Quickstart: Ingest custom metrics with EDOT
Use this quickstart to send custom metrics to Elastic using the Elastic Distribution of the OpenTelemetry Collector (EDOT).
You’ll install a lightweight EDOT Collector, configure a minimal Open Telemetry Protocol (OTLP) metrics pipeline, and verify the data in Elastic Observability.

## Prerequisites

- An Elastic deployment (Serverless, Elastic Cloud Hosted, or self-managed)
- An Observability project Kibana instance
- Permissions to create API keys
- A system to run the EDOT Collector (Docker, host, or VM)
- Optional: An application that emits OpenTelemetry metrics

<stepper>
  <step title="Create an Elastic API key">
    In your Elastic Observability deployment:
    1. Go to **Management** > **Stack Management** > **API keys**.
    2. Create a new API key and copy the value.
    3. Note your deployment's OTLP ingest endpoint.
  </step>

  <step title="Run the EDOT Collector with a minimal metrics pipeline">
    Update the `collector-config.yaml` file with the following Collector configuration to receive OTLP metrics and export them to Elastic:
    ```yaml
    receivers:
      otlp:
        protocols:
          http:
          grpc:

    processors:
      batch: {}

    exporters:
     otlphttp:
       endpoint: "<OTLP_ENDPOINT>"
       headers:
         Authorization: "ApiKey <YOUR_API_KEY>"

    service:
     pipelines:
       metrics:
         receivers: [otlp]
         processors: [batch]
         exporters: [otlphttp]
    ```
    Run the configuration, for example with Docker:
    ```bash
    docker run --rm \
      -v $(pwd)/collector-config.yaml:/etc/otel/config.yaml \
      -p 4317:4317 -p 4318:4318 \
      docker.elastic.co/observability/otel-collector:latest
    ```
  </step>

  <step title="Optional: Port conflict handling">
    If you encounter a port conflict error like:
    ```bash
    bind: address already in use
    ```
    Add the following to the `service` section:
    ```yaml
    service:
     telemetry:
       metrics:
         address: localhost:8889 
    ```
    You can also verify if the Collector is listening on the correct ports:
    ```bash
    lsof -i :4318 -i :4317
    ```
  </step>

  <step title="Send a custom metric">
    In this Python example, you use an application that emits OTLP metrics. For other languages, refer to the [contrib OpenTelemetry documentation](https://opentelemetry.io/docs/getting-started/dev/).
    ```python
    from opentelemetry import metrics
    from opentelemetry.exporter.otlp.proto.http.metric_exporter import OTLPMetricExporter
    from opentelemetry.sdk.metrics import MeterProvider
    from opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader

    exporter = OTLPMetricExporter(endpoint="http://localhost:4318/v1/metrics")
    reader = PeriodicExportingMetricReader(exporter)
    provider = MeterProvider(metric_readers=[reader])
    metrics.set_meter_provider(provider)

    meter = metrics.get_meter("custom-app")

    temperature = meter.create_observable_gauge(
        "custom.temperature",
        callbacks=[lambda options: [metrics.Observation(26.7)]],
    )

    input("Sending metrics periodically... press Enter to stop")
    ```
  </step>

  <step title="Verify metrics in {{product.observability}}">
    In Kibana:
    1. Go to **Infrastructure** > **Metrics Explorer**.
    2. Search for `custom.temperature`.
    3. Visualize or aggregate the metric data.
  </step>
</stepper>


## Explore your metrics

You've successfully set up a minimal OTLP metrics pipeline with the EDOT Collector. Your custom metrics are flowing into Elastic Observability and can be visualized in Kibana.
Now you can:
- Use **Metrics Explorer** to create custom visualizations and dashboards
- Set up alerts based on your custom metrics
- Aggregate and analyze metric trends over time


## Extend your setup

You can expand your metrics collection setup in several ways:
- Add more receivers to collect additional metrics
- Configure the same Collector to send logs and traces alongside metrics
