A longer form of Metrics for the Win! recorded for J4K, which occurred in October of 2020.
Understanding application behavior is important in any environment. When thinking about metrics in the context of observable distributed systems, most associate application or service-level metrics with memory usage or throughput, but what else can you understand about your application using metrics?

It will also compare the capabilities of MicroProfile Metrics and the OpenTelemetry Java library.
