Class HeapMemoryAfterGCWorkerMetric

java.lang.Object

software.amazon.kinesis.worker.metric.impl.jmx.HeapMemoryAfterGCWorkerMetric

All Implemented Interfaces:

WorkerMetric

public class HeapMemoryAfterGCWorkerMetric
extends Object
implements WorkerMetric

Memory WorkerMetricStats that reads the heap memory after GC. The way memory usage is calculated that, all the available memory pools are read except Eden (as this is allocation buffer) and used memory and total memory is computed. Then percentage is computed by dividing used memory by total memory.

Method Detail

getShortName

public String getShortName()

Description copied from interface: WorkerMetric

WorkerMetricStats short name that is used as attribute name for it in storage.

Specified by:

getShortName in interface WorkerMetric

Returns:

short name for the WorkerMetricStats

capture

public WorkerMetric.WorkerMetricValue capture()

Description copied from interface: WorkerMetric

Current WorkerMetricValue. WorkerMetricValue is a normalized percentage value to its max configured limits. E.g., if for a worker max network bandwidth is 10Gbps and current used bandwidth is 2Gbps, then WorkerMetricValue for NetworkWorkerMetrics will be 20 (%).

Specified by:

capture in interface WorkerMetric

Returns:

WorkerMetricValue between 0 and 100 (both inclusive)

getOperatingRange

public OperatingRange getOperatingRange()

Description copied from interface: WorkerMetric

Gets the operating range for this workerMetrics

Specified by:

getOperatingRange in interface WorkerMetric

Returns:

Operating range for this workerMetrics

getWorkerMetricType

public WorkerMetricType getWorkerMetricType()

Description copied from interface: WorkerMetric

Type of the current WorkerMetricStats.

Specified by:

getWorkerMetricType in interface WorkerMetric

Returns:

WorkerMetricType
