Class AggregatedValue

java.lang.Object

org.hawkular.metrics.model.AggregatedValue

public class AggregatedValue
extends Object

An aggregated gauge value. This value is the result of applying a function to data from one or more metrics. The input data can itself be raw or aggregated.

Method Detail

getType

public String getType()

The aggregation function used to produce this value, e.g., max, min, sum, count, etc.

Note: Once we have more functions support in place, this will likely be replaced by a more strongly typed object.

Returns:

type

getSrcMetric

public String getSrcMetric()

When the aggregated value is the result of applying a function to data from multiple metrics, this might be set for certain functions. For example, if we are computing the max or min from a set of data points from multiple metrics, then srcMetric along with srcMetricInterval will tell us from which metric that value came.

Returns:

source metrics

getSrcMetricInterval

public Interval getSrcMetricInterval()

When the aggregated value is the result of applying a function to data from multiple metrics, this might be set for particular functions. For example, if we are computing the max or min from a set of data points from multiple metrics, srcMetricInterval along with srcMetric will tell us from which metric that value came.

Returns:

source metric interval

getValue

public double getValue()

getTimeUUID

public UUID getTimeUUID()

This will be set for certain functions that basically perform filtering. For example, if we are computing the max or min, then timestamp gives us the collection time of the input data point that is the max or min.

Returns:

time UUID

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
