Hi! I've been working with some monitoring of the cluster through the ClusterMetrics provided in Akka 2.3.9 using hyperic-sigar-1.6.4. I've been comparing what is displayed in top and what I get by listening to ClusterMetricsChanged events in the cluster. The numbers coming in ClusterMetricsChanged doesn't at all seem to match what I see in top.
I'm running this on Amazon EC2 m3.medium & m3.large instances. I'm using the default settings for the metrics collection. For example I have the node running steadily on load at 1-1.5 but node metrics says systemLoad is around 0.1 occationally jumping up over 1 and then immediately down to 0.1 (or there around) and all that time top is showing steadily over 1. Essentially same thing with cpuCombined. I'm more or less using the example "Subscribe to metrics events" at http://doc.akka.io/docs/akka/2.3.9/java/cluster-usage.html VisualVM shows cpu usage as expected. Anyone seen anything like this? -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
