Implementations

Sealed Trait

ExecutorMetricType is a Scala sealed trait which means that all of the implementations are in the same compilation unit (a single file).

Executor Metric Getters (Ordered ExecutorMetricTypes)

ExecutorMetricType defines an ordered collection of ExecutorMetricTypes:

  1. JVMHeapMemory
  2. JVMOffHeapMemory
  3. OnHeapExecutionMemory
  4. OffHeapExecutionMemory
  5. OnHeapStorageMemory
  6. OffHeapStorageMemory
  7. OnHeapUnifiedMemory
  8. OffHeapUnifiedMemory
  9. DirectPoolMemory
  10. MappedPoolMemory
  11. ProcessTreeMetrics
  12. GarbageCollectionMetrics

This ordering allows for passing metric values as arrays (to save space) with indices being a metric of a metric type.
