public final class OrcaServiceImpl
extends Object
implements io.grpc.BindableService

Implements a BindableService that generates Out-Of-Band server metrics. Register the returned service to the server, then a client can request for periodic load reports.

Method Detail

createService

public static io.grpc.BindableService createService(ScheduledExecutorService timeService,
                                                    io.grpc.services.MetricRecorder metricsRecorder,
                                                    long minInterval,
                                                    TimeUnit timeUnit)

Constructs a service to report server metrics. Config the report interval lower bound, the executor to run the timer, and a MetricRecorder that contains metrics data.

Parameters:

minInterval - configures the minimum metrics reporting interval for the service. Bad configuration (non-positive) will be overridden to service default (30s). Minimum metrics reporting interval means, if the setting in the client's request is invalid (non-positive) or below this value, they will be treated as this value.
