You can replace the failure detector with something like this:
import akka.remote.PhiAccrualFailureDetector
import akka.event.EventStream
import com.typesafe.config.Config
class LoggingPhiAccrualFailureDetector(config: Config, ev: EventStream)
extends PhiAccrualFailureDetector(config, ev) {
override def phi: Double = {
val p = super.phi
println(s"current phi $p") // you could do proper logging with the
EventStream
p
}
}
and define the full class name in config property
akka.cluster.failure-detector.implementation-class
GC pauses are problematic and typically generates false positives, but you
have perhaps tuned your app for low latency GC.
Cheers,
Patrik
