Monitor TempoStack instances

The configuration for monitoring TempoStack instances is exposed in the CR:

yaml Copy

apiVersion: tempo.grafana.com/v1alpha1
kind: TempoStack
spec:
  observability:
    metrics:
      createServiceMonitors: true
      createPrometheusRules: true
    tracing:
      sampling_fraction: 1.0
      jaeger_agent_endpoint: localhost:6831

Configure distributed tracing of operands

All Tempo components as well as the Tempo Gateway support the export of traces in thrift_compact format.

Deploy OpenTelemetry collector sidecar

To deploy the OpenTelemetry collector, follow these steps:

1. Install OpenTelemetry Operator into the cluster.
2. Create an OpenTelemetryCollector CR that receives trace data in Jaeger Thrift format and exports data via OTLP to the desired trace backend.
3. Optional: Deploy tracing backend to store trace data.

yaml Copy

apiVersion: opentelemetry.io/v1alpha1
kind: OpenTelemetryCollector
metadata:
  name: sidecar-for-tempo
spec:
  mode: sidecar
  config: |
    receivers:
      jaeger:
        protocols:
          thrift_compact:

    exporters:
      otlp:
        endpoint: <otlp-endpoint>:4317
        tls:
          insecure: true

    service:
      pipelines:
        traces:
          receivers: [jaeger]
          exporters: [otlp]

Send trace data to OpenTelemetry sidecar

Finally, create a TempoStack instance that sets jaeger_agent_endpoint to report trace data to the localhost. The Tempo operator sets the OpenTelemetry inject annotation sidecar.opentelemetry.io/inject": "true to all TempoStack pods. The OpenTelemetry Operator will recognize the annotation, and it will inject a sidecar into all TempoStack pods.
