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
• OpenTelemetry Collector
  • Prometheus receiver

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': 'https://token@api.uptrace.dev/project_id' }

remote_write:
  - url: 'http://localhost:14318/api/v1/prometheus/write'
    headers: { 'uptrace-dsn': 'http://project2_secret_token@localhost:14317/2' }

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

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: otlp.uptrace.dev
    headers:
      headers: { 'uptrace-dsn': 'https://token@api.uptrace.dev/project_id' }

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

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

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