Ingesting Prometheus metrics into Uptrace

There are 2 ways to ingest Prometheus metrics into Uptrace:

• Using Prometheus Remote Write with the Uptrace endpoint.
• Using the OpenTelemetry Collector Prometheus receiver and the OTLP exporter.

Prometheus remote write

Prometheus Remote Write allows Prometheus to send its collected metrics data to a long-term storage solution such as Uptrace.

You can configure Prometheus Remote Write using the following endpoint:

remote_write:
  - url: 'https://api.uptrace.dev/api/v1/prometheus/write'
    headers: { 'uptrace-dsn': '<FIXME>' }

OpenTelemetry Collector

Prometheus receiver

Prometheus uses a pull model for data collection. In a pull-based model, Prometheus acts as a client, actively retrieving metrics from the targets (servers, applications, or other data sources) it monitors.

You can use OpenTelemetry Collector instead of Prometheus to pull metrics using the 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 using OpenTelemetry protocol:

exporters:
  otlp:
    endpoint: https://otlp.uptrace.dev:4317
    headers:
      headers: { 'uptrace-dsn': '{{ dsn }}' }

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