This score is updated whenever the agent notices any changes in the response, from a set of randomly probed agents. This value ranges from 0-8, the lowest indicating the agent is healthy and vice versa. + This metric describes a node's perception of its own health based on how well it is meeting the soft real-time requirements of the protocol. This metric ranges from 0 to 8, where 0 indicates "totally healthy". This health score is used to scale the time between outgoing probes, and higher scores translate into longer probing intervals.
