English Intermediate Other

You have probably heard of OpenTelemetry in the context of traces. But did you know OpenTelemetry also supports metrics with a comprehensive, forward-looking data model and SDKs? One thinks of Prometheus when it comes to metrics, but Otel metrics provide exciting ideas such as cumulative deltas, exponential histograms, and many more! This talk will demystify everything about Otel Metrics, from the data model to APIs to how to get started. We will cover the differences between Otel Metrics and Prometheus and reasons to get excited by using Otel Metrics.
