eventlog-live-0.9.0.0: data/help.progDesc.txt

Use eventlog-live-otlp to export eventlog telemetry to an OTLP endpoint.

The following sends your application's eventlog over a named pipe and exports the resulting telemetry to an OTLP gRPC endpoint at "localhost:4317".

  # Configure OpenTelemetry exporter
  export OTEL_SERVICE_NAME="your-application"
  export OTEL_EXPORTER_OTLP_PROTOCOL="grpc"
  export OTEL_EXPORTER_OTLP_ENDPOINT="localhost:4317"

  # Create a pipe for the eventlog
  mkfifo "/tmp/your-application.eventlog"

  # Start your application
  your-application                                   \
    +RTS                                             \
      -l                                             \
      -ol"/tmp/your-application.eventlog"            \
      -hT                                            \
      --eventlog-flush-interval=1

  # Start eventlog-live-otlp
  eventlog-live-otlp                                 \
    --eventlog-file="/tmp/your-application.eventlog" \
    -hT                                              \
    --eventlog-flush-interval=1
