Features

Tracing

  • Using the official OpenTelemetry SDK
  • Minimal auto-instrumentation for requests, console commands, consumers and doctrine
  • Trace context propagation from incoming requests to consumers, outgoing http calls and databases (using sqlcommenter)
  • Configurable blacklisting of requests by path to avoid useless traces, eg. /metrics or /_healthz
  • Automatic log inclusion with configurable log level and channels

Metrics

  • Using the Prometheus Client
  • Minimal auto-instrumentation for common request, consumer and message metrics (see list of provided default metrics).
  • Autoconfigurable metric providers, see below.

Logging

  • Adds trace context to logs for correlation, with customizable keys.

Baggage

  • Using the official OpenTelemetry SDK
  • Baggage propagation from incoming requests to consumers and outgoing http calls

Health

  • A simple endpoint to expose application health (default: /_healthz)
  • Autoconfigurable healthcheck interface to add healthchecks to be made for global application health
