```
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 Summary

Fields
Modifier and Type	Field	Description
`io.tehuti.metrics.Sensor`	`directMemoryCapacity`	An estimate of the total capacity of the buffers in this pool.
`io.tehuti.metrics.Sensor`	`directMemoryPoolCount`	An estimate of the number of buffers in the pool.
`io.tehuti.metrics.Sensor`	`directMemoryUsage`	Returns an estimate of the memory that the Java virtual machine is using for this buffer pool.
`io.tehuti.metrics.Sensor`	`heapUsage`	The current memory usage of the heap that is used for object allocation.

- Field Detail
  - 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.
