type PathHandler 

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

PathHandler maintains a notion of the current path through the state machine. It allows to close a path and open new path. Each path is identified by a unique (randomly generated) uuid. Along each path, we can capture information about relevant Steps (each step is represented by a Zerolog Event). In case there is no currently open path, the PathHandler still returns a Step, but such steps are logged as telemetry errors.

func NewPathHandler 

func NewPathHandler(log zerolog.Logger) *PathHandler

NewPathHandler instantiate a new PathHandler. The PathHandler has no currently open path Logger MUST include `chain` parameter as part of log context with corresponding chain ID to correctly map telemetry events to chain.

func (*PathHandler) CloseCurrentPath 

func (p *PathHandler) CloseCurrentPath() *PathHandler

CloseCurrentPath closes the current path. Repeated calls to CloseCurrentPath are handled. All Details hereafter, until a new Path is started, are logged as telemetry Errors. Returns self-reference for chaining

func (*PathHandler) IsCurrentPathClosed 

func (p *PathHandler) IsCurrentPathClosed() bool

IsCurrentPathClosed if and only if the most recently started path has been closed.

func (*PathHandler) NextStep 

func (p *PathHandler) NextStep() *zerolog.Event

NextStep returns a Zerolog event for the currently open path. If the current path is closed, the event will be logged as telemetry error.

func (*PathHandler) StartNextPath 

func (p *PathHandler) StartNextPath(view uint64) *PathHandler

StartNextPath starts a new Path. Implicitly closes previous path if still open. Returns self-reference for chaining

type SlashingViolationsConsumer 

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

SlashingViolationsConsumer is an implementation of the notifications consumer that logs a message for any slashable offenses.

func NewSlashingViolationsConsumer 

func NewSlashingViolationsConsumer(log zerolog.Logger) *SlashingViolationsConsumer

func (*SlashingViolationsConsumer) OnDoubleProposeDetected

func (c *SlashingViolationsConsumer) OnInvalidTimeoutDetected(err model.InvalidTimeoutError)

func (*SlashingViolationsConsumer) OnVoteForInvalidBlockDetected added in v0.23.9 

func (c *SlashingViolationsConsumer) OnVoteForInvalidBlockDetected(vote *model.Vote, proposal *model.Proposal)

type TelemetryConsumer 

type TelemetryConsumer struct {
	NoopTimeoutCollectorConsumer
	NoopVoteCollectorConsumer
	// contains filtered or unexported fields
}

TelemetryConsumer implements the hotstuff.Consumer interface. consumes outbound notifications produced by the HotStuff state machine. For this purpose, the TelemetryConsumer enriches the state machine's notifications:

  • The goal is to identify all events as belonging together that were emitted during a path through the state machine.
  • A path through the state machine begins when: -- a block has been received -- a QC has been constructed -- a TC has been constructed -- a partial TC has been constructed -- a local timeout has been initiated
  • Each path through the state machine is identified by a unique id.

Additionally, the TelemetryConsumer reports events related to vote and timeout aggregation but those events are not bound to a path, so they are reported differently. Generally, the TelemetryConsumer could export the collected data to a variety of backends. For now, we export the data to a logger.

Telemetry does NOT capture slashing notifications
