Ingesting Prometheus metrics into Uptrace

You can pull Prometheus metrics using the corresponding OpenTelemetry Collector receiver and then export the data to Uptrace using OpenTelemetry protocol.

OpenTelemetry Collector

OpenTelemetry Collector is a proxy service between your application and a distributed tracing tool. Collector receives telemetry data, transforms the data, and then exports it to tracing tools that can store the data permanently.

Collector can also act as an agent that pulls telemetry data from monitored systems, for example, Redis or filesystem metrics.

Prometheus receiver

You can use OpenTelemetry Collector to pull Prometheus metrics using prometheus_simple receiver:

receivers:
  prometheus_simple:
    collection_interval: 10s
    endpoint: '172.17.0.5:9153'
    metrics_path: '/metrics'
    use_service_account: false
    tls:
      ca_file: '/path/to/ca'
      cert_file: '/path/to/cert'
      key_file: '/path/to/key'
      insecure_skip_verify: true

And then export the metrics to Uptrace:

exporters:
  otlp:
    endpoint: localhost:14317
    headers:
      headers: { 'uptrace-dsn': 'http://project2_secret_token@localhost:14317/2' }

service:
  pipelines:
    metrics:
      receivers: [prometheus_simple]
      exporters: [otlp]
