Observability principles — logs vs metrics vs traces, structured logging, distributed tracing, span/trace context, cardinality control, SLI/SLO/SLA, RED method, USE method, alerting on symptoms vs causes. Auto-load when adding logging, choosing a metric, instrumenting distributed tracing, defining SLIs/SLOs, designing alerts, or discussing observability budgets.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-OBSERVABILITY --> # Observability Three signals, each with a distinct job. Use the right one for the right question. ## The Three Pillars **Logs** — discrete events with context. Right for: debugging specific incidents, audit trails, free-text search. - Emit at decision points and error boundaries, not in loops. - Use structured key-value format; never interpolate variables into free-form strings. - Include a correlation ID on every line — trace parent ID if a trace exists. **Metrics** — numeric aggregations over time. Right for: dashboards, SLOs, alerting thresholds. - Pre-aggregate; do not stream raw events into a metrics backend. - Label only stable, low-cardinality dimensions (region, status_code, service) — never user ID, request ID, or email. **Traces** — causal chain of operations across services. Right for: latency attribution, dependency mapping. - A span represents one unit of work; parent/child links form the trace. - Propagate context headers at every service boundary — OpenTelemetry W3C trace context. - Put high-cardinality attributes (user ID, document ID) in span attributes, not metric labels. ## Structured Logging …

How to install
mdr add lugassawan/swe-workbench/principle-observability@sha256:d075f8bd6f0e6a64The line at the top of this page pins the label git:20260828.71a6399, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
