A method to check if a follower node is alive or unresponsive

[aley1]

@sakno,

Is there a way to detect or check if a follower node is alive (or unresponsive) through DotNext Tcp library?
e.g. to check if Node is available before sending a message to the node.

IClusterMember.Status. However, it is not practical for the purpose you mentioned. Due to async nature, the member may become unresponsive immediately after status check but before message send:

if (member.IsAvailable) // true
  // member becomes unavailable
  member.SendAsync(); // exception

I've tried checking RaftClusterMember.Status of each member in the raft cluster and the status is always 'unknown'.
example:
if (IsLeader())
{
foreach (RaftClusterMember member in _raftCluster.Members)
{
Console.WriteLine($"Cluster member status: {member.Status}");
}
}
}
Could it be a bug?

Seems like a bug, for HTTP it works as expected. Could you please create an issue? #139
