Observability Tools
Instruments for understanding what your distributed system is doing at runtime.
// concept
Observability = Metrics + Logs + Traces. Together they provide visibility into system behavior, enabling debugging, alerting, and capacity planning.
Metrics Collector
Collect counters, gauges, and rates from your services. Aggregate and expose for monitoring dashboards.
Histogram
Track value distributions with configurable buckets. Compute percentiles (p50, p95, p99) from observations.
Structured Logger
Emit JSON log lines with consistent fields. Enables machine-parseable, searchable, and filterable logs.
Trace ID Propagation
Propagate a unique trace ID across service boundaries. Correlate logs and spans for distributed tracing.
