Jaeger
A CNCF graduated open-source distributed tracing platform that ingests OpenTelemetry and OTLP traces, showing request paths, latency, errors, service dependencies, and multiple storage options.
Why it’s here
Problems across multiplayer, identity, matchmaking, or economy services can be followed from one slow request to the responsible span and service.
Best fit
Analytics, feedback, support, and updates keep a released game healthy over time.
Before you commit
It is not a complete replacement for logs and metrics; govern sampling, storage, retention, and sensitive span attributes, and expect limited value for small monoliths or offline games.
