Devs, Transform (Your Data) and Roll Out!: Learning and Leveraging OTTL
summary
OpenTelemetry Transformation Language (OTTL) runs in the Collector’s processing stage and powers the transform, filter and tail sampling processors, letting you write conditional, cross-field edits that standard processors cannot. It supports editor and converter functions, paths like span.attributes or resource.attributes, regex-based matching and chaining multiple transformations top-to-bottom. Use cases shown include redacting emails to remove PII, normalizing inconsistent environment labels, and reducing volume; try statements live at ottl.run playground and gate changes with conditional where clauses.
