Jan Høydahl resolved SOLR-16605. -------------------------------- Fix Version/s: 9.2 Resolution: Fixed Since the commit was released in 9.2, I'll go ahead and resolve this. Please open another Jira if you feel there is a better way to pick up CPU load from Java. > CPU in UI cloud->nodes is always 0%, even when Solr is very busy. > ----------------------------------------------------------------- > > Key: SOLR-16605 > URL: https://issues.apache.org/jira/browse/SOLR-16605 > Project: Solr > Issue Type: Bug > Components: Admin UI > Affects Versions: 9.1 > Reporter: Shawn Heisey > Assignee: Shawn Heisey > Priority: Major > Fix For: 9.2 > > Attachments: fixcpuadminui-1.patch > > > The Cloud->Nodes section of the admin UI is always reporting 0% CPU even on > very busy Solr nodes. I thought the attached patch would fix t, but it > doesn't seem to be working. Instead of always 0%, it now shows an occasional > 50% or 100%... and even rarer is a different percentage like 84% or 17%. The > Solr process at that time was usng about 180% CPU (two CPUs in AWS instance). > Using OperatingSystemMXBean from com.sun instead of java.lang seemed to work > fine in a quick test program, but it's not working in Solr. I am trying this > on Ubuntu Linux with OpenJDK 17 and 11. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
