# Jaeger

> Configuring the Jaeger backend (Self-Hosted)

### Getting Started

<img src="https://d15jtxgb40qetw.cloudfront.net/jaeger.svg" alt="jaeger" className="not-prose h-20" />

Version v1.35 of Jaeger introduced the ability to receive OpenTelemetry trace data via the OpenTelemetry Protocol (OTLP). This allows to create a new Jaeger backend by simply specifying the Jaeger OTLP gRPC unencrypted URL.

### Configuring Destination Fields

<Accordion title="Supported Signals:">
  ✅ Traces
  ❌ Metrics
  ❌ Logs
  ❌ Profiles
</Accordion>

* **JAEGER\_URL** `string` : Jaeger OTLP gRPC Endpoint. The format is `host:port`, host is required, port is optional and defaults to the default OTLP gRPC port `4317`
  * This field is required
* **JAEGER\_TLS\_ENABLED** `boolean` : Enable TLS. Secure connection
  * This field is optional and defaults to `False`
* **JAEGER\_CA\_PEM** `string` : Certificate Authority. When using TLS, provide the CA certificate in PEM format to verify the server. If empty uses system root CA
  * This field is optional
  * Example: `-----BEGIN CERTIFICATE-----`

### Adding Destination to Odigos

There are two primary methods for configuring destinations in Odigos:

##### **Using the UI**

<Steps>
  <Step>
    Use the [Odigos CLI](https://docs.odigos.io/cli/odigos_ui) to access the UI

    ```bash theme={null}
    odigos ui
    ```
  </Step>

  <Step>
    Click on `Add Destination`, select `Jaeger` and follow the on-screen instructions
  </Step>
</Steps>

##### **Using Kubernetes manifests**

<Steps>
  <Step>
    Save the YAML below to a file (e.g. `jaeger.yaml`)

    ```yaml theme={null}
    apiVersion: odigos.io/v1alpha1
    kind: Destination
    metadata:
      name: jaeger-example
      namespace: odigos-system
    spec:
      data:
        JAEGER_URL: <Jaeger OTLP gRPC Endpoint>
        # Note: The commented fields below are optional.
        # JAEGER_TLS_ENABLED: <Enable TLS>
        # JAEGER_CA_PEM: <Certificate Authority>
      destinationName: jaeger
      signals:
      - TRACES
      type: jaeger
    ```
  </Step>

  <Step>
    Apply the YAML using `kubectl`

    ```bash theme={null}
    kubectl apply -f jaeger.yaml
    ```
  </Step>
</Steps>
