Enriching Telemetry Signals Through Lookups in the OTel Collector - João Duarte, Elastic

This talk covers the process of enriching telemetry signals using external data within the OpenTelemetry (OTel) Collector, presented by João Duarte from Elastic. The session addresses common challenges faced when augmenting telemetry with metadata that resides outside the collector, such as network nomenclature in YAML files or security audit logs needing cross-referencing with HTTP-based threat feeds. The speaker discusses the implementation of a new lookup processor designed to enhance observability pipelines by integrating contextual information into raw data. Attendees will learn about configuration examples, performance considerations like caching, and future developments regarding extensions for this enrichment processor.
