Class MappingAggregatorsRouter

java.lang.Object

org.ametiste.metrics.router.MappingAggregatorsRouter

All Implemented Interfaces:

AggregatorsRouter

public class MappingAggregatorsRouter
extends java.lang.Object
implements AggregatorsRouter

AggregatorsRouter implementation based on routing map,

Metric ids in routing map may contain wildcards.

Routing map should contain route with key "__default".

Its possible to have only "__default" route.

Since:

0.1.0

MappingAggregatorsRouter

public MappingAggregatorsRouter(java.util.Map<java.lang.String,java.util.List<MetricsAggregator>> aggregators)

Requires routing map with "__default" key route at least.

Parameters:

aggregators - - routing map aggregators

Method Detail

getAggregatorsForMetric

@Deprecated
public java.util.List<MetricsAggregator> getAggregatorsForMetric(java.lang.String metricIdentifier)

Deprecated.

Matches list of aggregators either by key or by prefixed key. Example of keys: "metric.that.needs.to.be.routed" matches as to key "metric.that.needs.to.be.routed" as to "metric.that.needs*" and "*" when "metric.is.to.be.routed" matches only "*" of those route keys

Specified by:

getAggregatorsForMetric in interface AggregatorsRouter

Parameters:

metricIdentifier - - id of metric for that route is defined. Note: id is already resolved one, in case if MetricsIdentifierResolver had a match for metric identifier, identifier might be different from initial name

Returns:

- list of MetricsAggregator that accept metric with id metricIdentifier if metricIdentifier didnt match any specific routes, default route aggregator list is returned.

aggregate

public void aggregate(java.lang.String metricIdentifier,
                      java.util.function.Consumer<MetricsAggregator> function)

Matches list of aggregators either by key or by prefixed key. Example of keys: "metric.that.needs.to.be.routed" matches as to key "metric.that.needs.to.be.routed" as to "metric.that.needs*" and "*" when "metric.is.to.be.routed" matches only "*" of those route keys

Specified by:

aggregate in interface AggregatorsRouter

Parameters:

metricIdentifier - - id of metric for that route is defined. Note: id is already resolved one, in case if MetricsIdentifierResolver had a match for metric identifier, identifier might be different from initial name

function - - consumer that should be applied to each of aggregators .
