Expensive Observability: The Cardinality Challenge - OpenObservability Talks S3E02
Manage episode 335706461 series 3252969
We all collect logs, metrics and perhaps traces and other data types, in support of our observability. But this can get expensive pretty quickly, especially in microservices based systems, in what is commonly known as “the cardinality problem”.
On this episode of OpenObservability Talks I’ll host Ben Sigelman, co-founder and the GM of Lightstep, to discuss this data problem and how to overcome it. Ben architected Google’s own planet-scale metrics and distributed tracing systems (still in production today), and went on to co-create the open-source OpenTracing and OpenTelemetry projects, both part of the CNCF.
The episode was live-streamed on 12 July 2022 and the video is available at https://youtu.be/gJhzwP-mZ2k
