You can redact PII from OpenTelemetry telemetry data without modifying application code by using the OpenTelemetry Transformation Language (OTTL) to hash sensitive identifiers and mask patterns in log records within the Collector pipeline.

The OpenTelemetry Transformation Language (OTTL) is used in a Collector pipeline to filter, enrich, and manipulate telemetry data, enabling complex scenarios like attribute normalization, conditional routing, and intelligent sampling.

You normalize attribute names and enrich spans with infrastructure metadata by applying standardized OTTL functions and path expressions within the OpenTelemetry Collector transformation processor configuration.

Yes, you can control attribute cardinality and implement intelligent sampling using OTTL to optimize pipeline efficiency and route telemetry data to appropriate backends within OpenTelemetry Collector environments.

The best way to conditionally route telemetry data to different backends is by implementing production-ready processing logic through standardized OTTL functions and path expressions in the OpenTelemetry Collector.

No specific external dependencies are required to implement OTTL transformations; the skill provides a comprehensive reference and pattern library for configuring the transformation processor directly within standard OpenTelemetry Collector environments.
