Nested Messages

routerrpc.MissionControlConfig

Field	gRPC Type	REST Type
half_life_seconds The amount of time mission control will take to restore a penalized node or channel back to 50% success probability, expressed in seconds. Setting this value to a higher value will penalize failures for longer, making mission control less likely to route through nodes and channels that we have previously recorded failures for.	uint64	string
hop_probability The probability of success mission control should assign to hop in a route where it has no other information available. Higher values will make mission control more willing to try hops that we have no information about, lower values will discourage trying these hops.	float	number
weight The importance that mission control should place on historical results, expressed as a value in [0;1]. Setting this value to 1 will ignore all historical payments and just use the hop probability to assess the probability of success for each hop. A zero value ignores hop probability completely and relies entirely on historical results, unless none are available.	float	number
maximum_payment_results The maximum number of payment results that mission control will store.	uint32	integer
minimum_failure_relax_interval The minimum time that must have passed since the previously recorded failure before we raise the failure amount.	uint64	string
