<div dir="ltr"><div>Hello hotspot-jfr-dev! </div><div><br></div>I'm Robert on the Java monitoring team at Red Hat. I've been working on building an <a href="https://github.com/open-telemetry/opentelemetry-java-contrib/tree/main/jfr-streaming">OpenTelemetry metrics gatherer using JFR</a>. The goal is to create an implementation that meets the OpenTelemetry <a href="https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/semantic_conventions/runtime-environment-metrics.md#jvm-metrics">specification</a> outlining metrics related to the JVM. The idea is to phase out and improve over the JMX metrics gathering implementation. However, the set of existing JFR events is missing a few data points required to accomplish this. I've identified some additions that will help to fill in the gaps <a href="https://docs.google.com/document/d/1oP8arX7FpZFnyA4nVi_k83eem7gh5w4_PJyPNZZFwRk/edit?usp=sharing">here</a>.<br><br>If the changes seem reasonable, the first additions I'll try to make are jdk.SerialGCHeapSummary and jdk.CPULinuxLoadAverage. Please let me know what you think.<br><br>Thank you! <div>Robert Toyonaga</div></div>
