final case class HeapMemory(address: Address, timestamp: Long, used: Long, committed: Long, max: Option[Long]) extends Product with Serializable

The amount of used and committed memory will always be <= max if max is defined. A memory allocation may fail if it attempts to increase the used memory such that used > committed even if used <= max is true (e.g. when the system virtual memory is low).

address

akka.actor.Address of the node the metrics are gathered at

timestamp

the time of sampling, in milliseconds since midnight, January 1, 1970 UTC

used

the current sum of heap memory used from all heap memory pools (in bytes)

committed

the current sum of heap memory guaranteed to be available to the JVM from all heap memory pools (in bytes). Committed will always be greater than or equal to used.

max

the maximum amount of memory (in bytes) that can be used for JVM memory management. Can be undefined on some OS.
