Instana

If you want to use Instana as the trace data store, you'll configure the OpenTelemetry Collector to receive traces from your system and then send them to both Tracetest and Instana. And, you don't have to change your existing pipelines to do so.

tip

Examples of configuring Tracetest with Instana can be found in the examples folder of the Tracetest GitHub repo.

Configuring OpenTelemetry Collector to Send Traces to Both Instana and Tracetest​

In your OpenTelemetry Collector config file:

  • Set the exporter to otlp/tracetest.
  • Set the endpoint to your Tracetest instance on port 4317.
tip

If you are running Tracetest with Docker, and Tracetest's service name is tracetest, then the endpoint might look like this http://tracetest:4317

Additionally, add another config:

  • Set the exporter to otlp/instana.
  • Set the endpoint to use the same OTLP stack as your agents. The correct endpoints can be found here.
  • Set the headers to have x-instana-key as key and a hash as value. This hash correspond to the INSTANA_AGENT_KEY value shown on Instana UI.

# this one and still use yours instead.

Configure Tracetest to Use Instana as a Trace Data Store​

Configure your Tracetest instance to expose an otlp endpoint to make it aware it will receive traces from the OpenTelemetry Collector. This will expose Tracetest's trace receiver on port 4317.

Connect Tracetest to Instana with the Web UI​

In the Web UI, (1) open Settings, and, on the (2) Tracing Backend tab, select (3) Datadog.

Instana

Connect Tracetest to Instana with the CLI​

Or, if you prefer using the CLI, you can use this file config.

type: DataStore
spec:
  name: Instana pipeline
  type: instana
  default: true

Proceed to run this command in the terminal and specify the file above.

tracetest apply datastore -f my/data-store/file/location.yaml
