Field Detail

config

private OutlierDetectionLoadBalancer.OutlierDetectionLoadBalancerConfig config

activeCallCounter

private volatile OutlierDetectionLoadBalancer.EndpointTracker.CallCounter activeCallCounter

inactiveCallCounter

private OutlierDetectionLoadBalancer.EndpointTracker.CallCounter inactiveCallCounter

ejectionTimeNanos

private java.lang.Long ejectionTimeNanos

ejectionTimeMultiplier

private int ejectionTimeMultiplier

Constructor Detail

EndpointTracker

EndpointTracker(OutlierDetectionLoadBalancer.OutlierDetectionLoadBalancerConfig config)

Method Detail

setConfig

void setConfig(OutlierDetectionLoadBalancer.OutlierDetectionLoadBalancerConfig config)

addSubchannel

boolean addSubchannel(OutlierDetectionLoadBalancer.OutlierDetectionSubchannel subchannel)

Adds a subchannel to the tracker, while assuring that the subchannel ejection status is updated to match the tracker's if needed.

removeSubchannel

boolean removeSubchannel(OutlierDetectionLoadBalancer.OutlierDetectionSubchannel subchannel)

containsSubchannel

boolean containsSubchannel(OutlierDetectionLoadBalancer.OutlierDetectionSubchannel subchannel)

getSubchannels

java.util.Set<OutlierDetectionLoadBalancer.OutlierDetectionSubchannel> getSubchannels()

incrementCallCount

void incrementCallCount(boolean success)

activeVolume

long activeVolume()

inactiveVolume

long inactiveVolume()

successRate

double successRate()

failureRate

double failureRate()

resetCallCounters

void resetCallCounters()

decrementEjectionTimeMultiplier

void decrementEjectionTimeMultiplier()

resetEjectionTimeMultiplier

void resetEjectionTimeMultiplier()

swapCounters

void swapCounters()

Swaps the active and inactive counters.

Note that this method is not thread safe as the swap is not done atomically. This is expected to only be called from the timer that is scheduled at a fixed delay, assuring that only one timer is active at a time.

ejectSubchannels

void ejectSubchannels(long ejectionTimeNanos)

unejectSubchannels

void unejectSubchannels()

Uneject a currently ejected address.

subchannelsEjected

boolean subchannelsEjected()

maxEjectionTimeElapsed

public boolean maxEjectionTimeElapsed(long currentTimeNanos)

toString

public java.lang.String toString()

Overrides:
