Metrics performance

#1

Hello. Looking at akka cluster metrics. https://doc.akka.io/docs/akka/current/cluster-metrics.html
Can’t find any information whatsoever about performance impact of using this. Can someone help ?
Thanks

It’s getting metrics from JMX and optionally Sigar periodically. That shouldn’t add much load. These metrics are collected, agreggated and then disseminated to other nodes in the Akka Cluster with a gossip protocol, which means sending a message to another random node once per second (or whatever the interval is). In total I don’t expect much performance impact.
