Constructor Detail

AggregatingMetricsService

public AggregatingMetricsService(AggregatorsRouter router,
                                 MetricsIdentifierResolver resolver,
                                 java.lang.String prefix)

Parameters:

router - AggregatorRouter that defines list of aggregators accepting metric with defined name

resolver - metric name to identifier resolver

prefix - prefix for metrics to be put before its name. Usually is configured for service to separate it from other metrics in stack

Method Detail

increment

public void increment(java.lang.String metricId,
                      int incrementValue)

Increments counter to incrementValue for metrics with id metricId

Specified by:

increment in interface MetricsService

Parameters:

metricId - identifier of metric

incrementValue - delta of increment

gauge

public void gauge(java.lang.String metricId,
                  int gaugeValue)

Increments gauge counter to gaugeValue for metric with id metricId

Specified by:

gauge in interface MetricsService

Parameters:

metricId - identifier of metric

gaugeValue - gauge value

Since:

0.2.0

createEvent

public void createEvent(java.lang.String metricId,
                        int eventValue)

Creates event in time with eventValue for metricId. Can be used to register definite values in time or events with time values (time of method call)

Specified by:

createEvent in interface MetricsService

Parameters:

metricId - identifier of metric

eventValue - logged event start time
