Hi, For policeman Jenkins it is highly shared... There are running 2 virtual machines (OSX and Windows) next to the main Jenkins build processor. This machine always has all 6 (12 HT) cores used and in most times approx. 40% of its 32 GiB of b*er ahm RUM...
But we can get the JVM process' CPU usage from the same MX bean. I think this one helps more :-) Uwe ----- Uwe Schindler uschind...@apache.org ASF Member, Apache Lucene PMC / Committer Bremen, Germany http://lucene.apache.org/ > -----Original Message----- > From: dawid.we...@gmail.com [mailto:dawid.we...@gmail.com] On Behalf > Of Dawid Weiss > Sent: Monday, April 27, 2015 10:05 PM > To: dev@lucene.apache.org > Subject: Re: Can test HEARTBEATs also print the CPU usage of the JVM > process? > > Hi Mike, > > I'm pretty sure it could, if permitted by the security manager. :) The problem > with this metric is that the CPU is not exclusively owned by Java so if you > have a shared system then the CPU usage may not tell you anything? > > Dawid > > > On Mon, Apr 27, 2015 at 4:54 PM, Michael McCandless > <luc...@mikemccandless.com> wrote: > > This can be helpful to differentiate a test that is in a busy loop > > (taking 100% CPU) vs a deadlock/hang (taking 0% CPU)... > > > > Is it easy/possible to get this from straight Java APIs? > > OperatingSystemMXBean maybe...? > > > > Mike McCandless > > > > http://blog.mikemccandless.com > > > > --------------------------------------------------------------------- > > To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For > > additional commands, e-mail: dev-h...@lucene.apache.org > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional > commands, e-mail: dev-h...@lucene.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
