Jaeger gRPC 🔗

Note: This is a valid Smart Agent monitor, but Smart Agent is deprecated. For details, see the Deprecation Notice. If you are using OpenTelemetry, consider using the native OpenTelemetry Jaeger receiver instead.

Description 🔗

This monitor runs a gRPC server that listens for Jaeger trace batches and forwards them to Splunk Observability Cloud (or the configured ingest host in the writer section of the agent config). By default, the server listens on localhost port 14250, but can be configured to anything.

Benefits 🔗

After you’ve configured the integration, you can:

  • View metrics using the built-in dashboard. For information about dashboards, see View dashboards in Observability Cloud.

  • View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.

  • Access Metric Finder and search for metrics sent by the monitor. For information about Metric Finder, see Use the Metric Finder.

Installation 🔗

Follow these steps to deploy the integration:

  1. Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:

  2. Configure the monitor, as described in the next section.

  3. Restart the Splunk Distribution of OpenTelemetry Collector.

Configuration 🔗

This monitor is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. The Smart Agent Receiver lets you use existing Smart Agent monitors as OpenTelemetry Collector metric receivers.

Using this monitor assumes that you have a configured environment with a functional Smart Agent release bundle on your system, which is already provided for x86_64/amd64 Splunk Distribution of OpenTelemetry Collector installation paths.

To activate this monitor in the Splunk Distribution of OpenTelemetry Collector, add the following to your configuration file:

    type: jaeger-grpc
    ... # Additional config

To complete the integration, include this monitor in a metrics pipeline. To do this, add the monitor to the service > pipelines > traces > receivers section of your configuration file.

      receivers: [smartagent/jaeger-grpc]

See the configuration example on GitHub for specific use cases that show how the Splunk OpenTelemetry Collector can integrate and complement existing environments.

For Prometheus, see the Prometheus Federation Endpoint Example in GitHub for an example of how the OTel Collector works with Splunk Enterprise and an existing Prometheus deployment.
