C# Class Akka.Cluster.ClusterMetricsCollector

INTERNAL API Cluster metrics is primarily for load-balancing of nodes. It controls metrics sampling at a regular frequency, prepares highly variable data for further analysis by other entities, and publishes the latest cluster metrics data around the node ring and local eventStream to assist in determining the need to redirect traffic to the least-loaded nodes. Metrics sampling is delegated to the IMetricsCollector. Smoothing of the data for each monitored process is delegated to the EWMA for exponential weighted moving average.

Gossip ( ) : void
GossipTo ( Akka.Actor.Address address ) : void
Publish ( ) : void

Publishes to the event stream.
ReceiveGossip ( MetricsGossipEnvelope envelope ) : void

Receives changes from peer nodes, merges remote with local gossip nodes, then publishes changes to the event stream for load balancing router consumption, and gossip back.
ReceiveState ( ClusterEvent state ) : void

Update the initial node ring for those nodes that are MemberStatus.Up
RemoveMember ( Member member ) : void

Removes a member from the node ring.
