I found the problem:
In file:
akka-cluster-metrics/src/main/scala/akka/cluster/metrics/Provision.scala
def verifiedSigarInstance: SigarProxy = {
> val sigar = new Sigar()
> sigar.getPid
> sigar.getLoadAverage
> sigar.getCpuPerc
> sigar
> }
def verifiedSigarInstance will always throws an exception when it attempts
to run sigar.getLoadAvarage. This causes the ClusterMetrics extension to
repeatedly attempt to provision sigar, but it never succeeds. Apparently
getLoadAverage simply isn't implemented for this OS in "sigar-loader" %
"1.6.6-rev002" which is the most recent version available and the version
referenced in the cluster metrics documentation.
Running a simple program with the following code will reproduce the error
under Windows 10 (possibly under Windows 7 too, I had trouble there some
months back)
import java.io.File; import org.hyperic.sigar.Sigar; import
> kamon.sigar.SigarProvisioner; object ExampleMain extends App {
> SigarProvisioner.provision(); val sigar = new Sigar() val loadAverage =
> sigar.getLoadAverage
}
>
The exception is:
Aug 20, 2016 2:52:59 PM kamon.sigar.SigarProvisioner discoverLocation INFO:
