Day-2 Reality Check: Taming Wasteful Telemetry - Juraci Paixão Kröhling & Elena Kovalenko

This talk covers the challenges of managing telemetry waste in observability pipelines, presented by Juraci Paixão Kröhling from OllyGarden and Elena Kovalenko from Delivery Hero. The speakers identify sources of telemetry waste, including unbounded cardinality and redundant data from over-eager auto-instrumentation, which can significantly inflate costs. They discuss how to utilize the OpenTelemetry Collector to optimize telemetry by dropping unnecessary attributes and transforming data, as well as the importance of the Instrumentation Score for assessing quality. Attendees will gain insights on identifying wasteful practices, evaluating cardinality, and implementing solutions that minimize costs while maintaining essential visibility.
