Class AggregationTemplate<T>

java.lang.Object

org.hawkular.metrics.model.AggregationTemplate<T>

public class AggregationTemplate<T>
extends Object

A template for creating pre-computed aggregate metrics. Templates are used for tenant-level configuration. A template applies to all metrics (of the specified type) for a tenant. For example, suppose we create a template for gauge metrics to compute the max and min at an interval of 5 minutes. Then for every gauge metric aggregate metrics that consist of the max and min will be computed every 5 minutes.

There are a couple caveats with using templates. First, the input must be a raw metric, be it gauge, availability, or a log event. Secondly, the input source can only be a single metric.

public AggregationTemplate()

Method Detail

getType

public MetricType<T> getType()

The type of metric to which the template applies.

Returns:

type

setType

public AggregationTemplate<T> setType(MetricType<T> type)

getInterval

public Interval getInterval()

How frequently the aggregate metrics created from this template should be updated.

Returns:

interval

setInterval

public AggregationTemplate<T> setInterval(Interval interval)

getFunctions

public Set<String> getFunctions()

The functions to apply on the source data.

Note: Once we have some of the functions support in place, this will most likely change to be a strongly typed collection.

Returns:

set of functions

setFunctions

public AggregationTemplate<T> setFunctions(Set<String> functions)

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
