fail

A failure detector is a tracker that receives events from multiple TCP connections and manages timeouts locally so that failed servers are detected - works with multiple connections.

API

  • .connecting(to): if you are the initiating party, call this; sets a timeout on the connection
  • .connected(to): call this when the connection is established (either on the client, or on the server)
  • .receive(from): call this for each message received from the other party (request or response)
  • .ungracefulDisconnectFn(from): returns a function that you can pass to .on('close'); triggers a disconnect if this occurs unexpectedly
  • .disconnect(from): call this for a graceful disconnect
  • .timeouts(): run the timeout interval manually
