Method Detail

getMonitoredEndpoint

MonitoredEndpoint<MonitorServiceConfiguration.EndpointConfiguration> getMonitoredEndpoint()

Returns:

the endpoint this service is able to sample

measureAvails

void measureAvails(Collection<MeasurementInstance<L,AvailType<L>>> instances,
                   Consumer<AvailDataPoint> consumer)

Checks the availabilities defined by instances and reports them back to the given consumer. If the relevant Endpoint is unreachable all instances are reported as Avail.DOWN.

Parameters:

instances - the availabilities to check

consumer - the consumer to send the results to

measureMetrics

void measureMetrics(Collection<MeasurementInstance<L,MetricType<L>>> instances,
                    Consumer<MetricDataPoint> consumer)

Collects the metrics defined by instances and reports them back to the given consumer.

Parameters:

instances - the metrics to check

consumer - the consumer to send the results to
