public class VeniceJVMStats
extends AbstractVeniceStats

Simple class that spins JVM platform stats into Venice stats. Explanations for these stats can be got from BufferPoolMXBean and MemoryMxBean

Field Details

directMemoryUsage

public final io.tehuti.metrics.Sensor directMemoryUsage

Returns an estimate of the memory that the Java virtual machine is using for this buffer pool. The value returned by this method may differ from the estimate of the total capacity of the buffers in this pool due to implementation.

directMemoryCapacity

public final io.tehuti.metrics.Sensor directMemoryCapacity

An estimate of the total capacity of the buffers in this pool. A buffer's capacity is the number of elements it contains and the value returned by this method is an estimate of the total capacity of buffers in the pool in bytes.

directMemoryPoolCount

public final io.tehuti.metrics.Sensor directMemoryPoolCount

An estimate of the number of buffers in the pool.

heapUsage

public final io.tehuti.metrics.Sensor heapUsage

The current memory usage of the heap that is used for object allocation. The amount of used memory in the returned memory usage is the amount of memory occupied by both live objects and garbage objects that have not been collected, if any.
