Class AccumulatingMetricsScope<KeyType>

java.lang.Object

com.amazonaws.services.kinesis.metrics.impl.DimensionTrackingMetricsScope

com.amazonaws.services.kinesis.metrics.impl.EndingMetricsScope

com.amazonaws.services.kinesis.metrics.impl.AccumulatingMetricsScope<KeyType>

Type Parameters:

KeyType - can be a class or object defined by the user that stores information about a MetricDatum needed by the user. The following is a example of what a KeyType class might look like: class SampleKeyType { private long timeKeyCreated; private MetricDatum datum; public SampleKeyType(long timeKeyCreated, MetricDatum datum){ this.timeKeyCreated = timeKeyCreated; this.datum = datum; } }

All Implemented Interfaces:

IMetricsScope

Direct Known Subclasses:

AccumulateByNameMetricsScope

public abstract class AccumulatingMetricsScope<KeyType>
extends EndingMetricsScope

An IMetricsScope that accumulates data from multiple calls to addData with the same name parameter. It tracks min, max, sample count, and sum for each named metric.

Method Detail

addData

public void addData(java.lang.String name,
           double value,
           StandardUnit unit)

Description copied from interface: IMetricsScope

Adds a data point to this IMetricsScope. Multiple calls against the same IMetricsScope with the same name parameter will result in accumulation.

Specified by:

addData in interface IMetricsScope

Overrides:

addData in class EndingMetricsScope

Parameters:

name - data point name

value - data point value

unit - unit of data point

getKey

protected abstract KeyType getKey(java.lang.String name)

Parameters:

name - key name for a metric

Returns:

the name of the key

addData

public void addData(KeyType key,
           java.lang.String name,
           double value,
           StandardUnit unit)

Adds data points to an IMetricsScope. Multiple calls to IMetricsScopes that have the same key will have their data accumulated.

Parameters:

key - data point key

name - data point name

value - data point value

unit - data point unit
