Cluster Metrics on Windows

[cessationoftime]

Using Akka 2.4.9 and Windows 10 I am unable to get CPU cluster metrics, I can only get HeapMemory metrics. Running the same code on a Ubuntu server I get both CPU metrics and Heap metrics.  I am using the factorial example located at: http://www.lightbend.com/activator/template/akka-sample-cluster-scala.  And I am running it in sbt with the following command "runMain sample.cluster.factorial.FactorialApp". Is there something I need to do to get this to work on windows?  Should it work on windows?

Thanks,

Chris

Hi,

Which metric collector are you using, the JMX or the SIGAR collector?

I have tried both of them with the same result on Windows. On Ubuntu I have only tried sigar.

Though sigar is the collector I would like to be able to use.

It can sometimes be difficult to setup loading of the native sigar library. Several alternatives are listed in docs http://doc.akka.io/docs/akka/2.4/java/cluster-metrics.html#Hyperic_Sigar_Provisioning

You should see warnings/errors in the log.

One thing that I've noticed is it seems to startup as JMX. But then it subsequently provisions Sigar. Though the provision is logged as an error message.

The log output looks like this:

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: Using location provided by hard coded value. Aug 20, 2016 2:52:59 PM kamon.sigar.SigarProvisioner provision INFO: Sigar library provisioned: C:\Users\cvanvranken\gits\Example\main\server-metrics\native\sigar-amd64-winnt.dll Exception in thread "main" org.hyperic.sigar.SigarNotImplementedException: This method has not been implemented on this platform at org.hyperic.sigar.SigarNotImplementedException.<clinit>(SigarNotImplementedException.java:28) at org.hyperic.sigar.Sigar.getLoadAverage(Native Method)

I found an issue for this listed in the hyperic/sigar github repo.

[Chris Van Vranken]

In the Sigar repository there is a comment in file: src/os/win32/win32_sigar.c, for function sigar_loadavg_get which says "there is no api for this info. closest i've seen is enumerating the entire process table and calculating an average based on process times."

Based on this comment it seems unlikely the issue will be resolved any time soon, if it gets fixed at all. So I think the verifiedSigarInstance function that ClusterMetrics calls should be changed so that the getLoadAverage function is not called when running on Windows, otherwise Sigar will be unuseable there.

[Chris Van Vranken]

Someone responded to me in the hyperic sigar issue. Apparently this is implemented in the Boundary fork of sigar: https://github.com/boundary/sigar

Hi Chris,

Thank you for all this, very valuable information! Can you please file a ticket on the repo for further discussions to not have this accidentally lost?
