These guides help you sample trace volume, correlate traces with logs, and protect sensitive data. They also cover derived span fields, span links, and context propagation across services.
Control Traces Volume
Drop unwanted spans to reduce costs and noise
Tail Sampling
Sample traces at the collector by status, latency, span name, and more
PII Scrubbing
Remove sensitive data from traces before ingestion
Correlate Traces and Logs
Link traces with logs for unified debugging
Span Links
Connect causally related spans across async and batch workflows
Context Propagation
Keep one trace ID across function calls, threads, and service boundaries
Calculated Fields in Spans
Derive ready-to-query fields from OpenTelemetry span attributes
