New Feature: Added OTEL Tracing, Metrics and Pyroscope

As a wish to seriously improve the performance and memory-safety of fc2-live-dl-go, supports for OTEL and Pyroscope is added.

OTEL and Pyroscope are solutions for YOU to monitor and profile the program. No data is sent to us.

OpenTelemetry

OpenTelemetry provides an API that allows you to collect traces and metrics from the application.

By setting these environment variables:

OTEL_EXPORTER_OTLP_TRACES_ENABLED=true/false
OTEL_EXPORTER_OTLP_METRICS_ENABLED=true/false

You enable push-based telemetry. The telemetry must be send to a OTEL collector like the OTEL Agent or Grafana Alloy.

The parameters of OTEL can be changed using standard environment variables given by the OpenTelemetry project.

Prometheus

In combination with OTEL, we are also exposing the metrics at 0.0.0.0:3000/metrics. This comes included with OTEL.

Pyroscope

In addition to net/http/pprof, github.com/grafana/pyroscope-go/godeltaprof/http/pprof has been added to enable precise continous profiling via Pyroscope.

The endpoint is still 0.0.0.0:3000/debug/pprof.

Grafana Dashboard

A Grafana Dashboard is now available in the grafana directory

  • Fixed a memory leak when calling C.CString during concatenation.
  • Ignore empty files and dirs during concat.
