DmuTrace 2.0

DmuTrace by DJF is a lightweight tracing and diagnostics tool that gives developers and SREs clear, end-to-end visibility into how their applications behave. It captures execution paths, timing, and system events across processes and services with minimal overhead, turning raw telemetry into actionable insights. With an intuitive CLI and optional dashboard, DmuTrace helps you pinpoint latency spikes, race conditions, and resource bottlenecks before they impact users.

Key capabilities:

• End-to-end tracing across services, threads, and async boundaries
• Low-overhead, selective instrumentation you can enable or disable on demand
• High‑resolution timing with flame graphs and critical‑path analysis
• Correlation of traces, logs, and metrics via context propagation
• Integrations with OpenTelemetry exporters and common log/metrics stacks
• Data safeguards including field redaction, sampling, and retention controls
• Works locally, in CI, and in production with adaptive sampling
• Extensible architecture with plugins and language SDKs

Typical use cases:

• Profiling hot paths and optimizing performance regressions
• Debugging intermittent timeouts and race conditions
• Observing startup, cold‑boot, and deployment behavior
• Reproducing and analyzing production incidents in development

Technical highlights:

• Simple CLI and REST API for automation
• Lightweight agent and libraries
• Multi‑platform support

DmuTrace helps teams move from guesswork to evidence, shortening time to root cause and improving application reliability.
