 The rules are a translation of the JMX Metric Gatherer's [target systems](https://github.com/open-telemetry/opentelemetry-java-contrib/tree/main/jmx-metrics/src/main/resources/target-systems)
-based on the [JMX metric rule YAML schema](https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/instrumentation/jmx-metrics/javaagent/README.md#basic-syntax).

+### SystemCpuLoad
+The `SystemCpuLoad` metric is deprecated and Java versions 14+ now use `CpuLoad`. However, to avoid emitting double metrics, we stick to using `SystemCpuLoad` as it still works on newer versions.
