Types

type HealthMonitor

type HealthMonitor interface {
	// Subscribe returns a channel that will be notified for every health check.
	Subscribe() <-chan error
	// Start starts the health check.
	Start() error
	// Stop stops the health check.
	Stop() error
}

HealthMonitor defines the interface for monitoring the health of the sequencer.

func NewSequencerHealthMonitor

func NewSequencerHealthMonitor(log log.Logger, interval, unsafeInterval, safeInterval, minPeerCount uint64, rollupCfg *rollup.Config, node dial.RollupClientInterface, p2p p2p.API) HealthMonitor

NewSequencerHealthMonitor creates a new sequencer health monitor. interval is the interval between health checks measured in seconds. safeInterval is the interval between safe head progress measured in seconds. minPeerCount is the minimum number of peers required for the sequencer to be healthy.
