Logs, Metrics & Traces
The three pillars of observable Nimbus deployments — unified under one pipeline.
Structured Logging
Every loader event emits JSON lines to a ring buffer. Ship to your aggregator via the built-in Unix socket forwarder — no agent required.
{"ts":"2026-05-26T14:31:02Z","lvl":"info","msg":"payload_verified","sig":"ed25519","dur_ms":4}Prometheus Metrics
Expose counters, gauges, and histograms on :9091/metrics. Track license validations, injection latency, and ETW event throughput.
- nimbus_license_checks_total — counter
- nimbus_inject_duration_seconds — histogram
- nimbus_etw_events_total — counter per provider
Distributed Traces
W3C Trace Context propagation across loader → payload → kernel boundary. Export to Jaeger or OTLP-compatible backends with zero-code config.

Pro tip: Enable the--telemetry flag in your Nimbus loader config to activate all three pillars with a single toggle.
