OnEntityEjectionDueToEmergency is called whenever a bucket is found full and all of its keys are valid, i.e., each key belongs to an existing (key, entity) pair. Hence, adding a new key to that bucket will replace the oldest valid key inside that bucket. Note: in context of HeroCache, the key corresponds to the identifier of its entity.

func (*HeroCacheCollector) OnEntityEjectionDueToFullCapacity added in v0.25.2

OnKeyPutSuccess is called whenever a new (key, entity) pair is successfully added to the cache.

type HeroCacheMetricsRegistrationFunc added in v0.25.2

type HeroCacheMetricsRegistrationFunc func(uint64) module.HeroCacheMetrics

type HotstuffCollector

type HotstuffCollector struct {
	// contains filtered or unexported fields
}

HotstuffCollector implements only the metrics emitted by the HotStuff core logic. We have multiple instances of HotStuff running within Flow: Consensus Nodes form the main consensus committee. In addition each Collector node cluster runs their own HotStuff instance. Depending on the node role, the name space is different. Furthermore, even within the `collection` name space, we need to separate metrics between the different clusters. We do this by adding the label `committeeID` to the HotStuff metrics and allowing for configurable name space.

func (*HotstuffCollector) CommitteeProcessingDuration

func (hc *HotstuffCollector) CommitteeProcessingDuration(duration time.Duration)

CommitteeProcessingDuration measures the time which the HotStuff's core logic spends in the hotstuff.Committee component, i.e. the time determining consensus committee relations.

func (*HotstuffCollector) CountSkipped

func (hc *HotstuffCollector) CountSkipped()

CountSkipped counts the number of skips we did.

func (*HotstuffCollector) CountTimeout

func (hc *HotstuffCollector) CountTimeout()

func (*VerificationCollector) OnChunksAssignmentDoneAtAssigner added in v0.17.1

func (vc *VerificationCollector) OnChunksAssignmentDoneAtAssigner(chunks int)

OnChunksAssignmentDoneAtAssigner increments a counter that keeps track of the total number of assigned chunks to the verification node.

func (*VerificationCollector) OnExecutionResultReceivedAtAssignerEngine added in v0.19.0

func (vc *VerificationCollector) OnExecutionResultReceivedAtAssignerEngine()

OnExecutionResultReceivedAtAssignerEngine is called whenever a new execution result arrives at Assigner engine. It increments total number of received results.

func (*VerificationCollector) OnFinalizedBlockArrivedAtAssigner added in v0.17.1

func (vc *VerificationCollector) OnFinalizedBlockArrivedAtAssigner(height uint64)

OnFinalizedBlockArrivedAtAssigner sets a gauge that keeps track of number of the latest block height arrives at assigner engine. Note that it assumes blocks are coming to assigner engine in strictly increasing order of their height.

func (*VerificationCollector) OnVerifiableChunkSentToVerifier added in v0.17.1

func (vc *VerificationCollector) OnVerifiableChunkSentToVerifier()

OnVerifiableChunkSentToVerifier increments a counter that keeps track of number of verifiable chunks fetcher engine sent to verifier engine.

func (*VerificationCollector) SetMaxChunkDataPackAttemptsForNextUnsealedHeightAtRequester added in v0.22.0

func (vc *VerificationCollector) SetMaxChunkDataPackAttemptsForNextUnsealedHeightAtRequester(attempts uint64)

SetMaxChunkDataPackAttemptsForNextUnsealedHeightAtRequester is invoked when a cycle of requesting chunk data packs is done by requester engine. It updates the maximum number of attempts made by requester engine for requesting the chunk data packs of the next unsealed height. The maximum is taken over the history of all chunk data packs requested during that cycle that belong to the next unsealed height.
