JSON Log Tools
Parse JSON log lines, filter by severity, and extract distributed trace IDs.
Filtering JSON logs and trace IDs
Structured logging prints one JSON object per line. Tools parse, filter by level, and extract trace or correlation IDs for jumping into distributed tracing UIs during outages.
Log level fields vary (severity, level, log.level). Normalize mappings in your pipeline documentation. Trace IDs may nest inside attributes objects depending on OpenTelemetry exporter settings.
Filter aggressively before paste into tickets; include only relevant time windows.
Process JSON logs locally from production exports containing user identifiers.
