The member nodes of the cluster can collect system health metrics and publish that to other cluster nodes
and to the registered subscribers on the system event bus with the help of Cluster Metrics Extension.

Maintenance Release for Akka.NET 1.4**
Akka.NET v1.4.14 contains some significant bug fixes and improvements. It is a _highly recommended upgrade_ for all Akka.NET users.
Major Reduction in Idle CPU Usage and Latency for Akka.Remote**
One of the most important fixes introduced in [Akka.NET v1.4.14 is the new self-tuning batching system for Akka.Remote's DotNetty transport](https://getakka.net/articles/remoting/performance.html), which simulatneously reduces idle CPU consumption on low-traffic systems by as much as 55% while improving latency by a factor of 10 for low-traffic systems.
The batching system no longer needs to be configured - it can scale up and down with workload automatically in order to both maximize throughput with a minimal amount of latency. You can read more about it here: https://getakka.net/articles/remoting/performance.html
