    Solved: vRops - Memory Capacity/Time Remaining is not generated in Linux CentOS7/8

      Hi all,

       

      I write this post in case this can be useful for someone else.

       

      Enviroment description:

      vRops 8.0/8.1

      VMware ESXi 6.7

      VMware vCenter Server 6.7

      Guest OS: Linux CentOS 7/8

      VMware tools/Open-vm-tools version: 10.1.x – 10.3.x

      vRops is not generating Memory Capacity Remaining or Memory Time Remaining Graph

      vRops is not generating metrics: All Metrics > Capacity Analytics Generated > Memory Capacity Remaining, Memory Recommended Size or Time Remaining.

      vRops is not collecting All Metrics > Guest > Page in Rate per second metric from CentOS VM Server.

      Solution description:

       

      Verify system locale configured in CentOS VM Server.

       

      In my case, the server was configured with Spanish system locale:

       

      # localectl

        System Locale: LANG=es_ES.UTF-8

        VC Keymap: es

        X11 Layout: es

       

      Change system locale to en_US.UTF-8 and restart vmtoolsd daemon.

       

      # localectl set-locale LANG=en_US.UTF-8

       

      # localectl

         System Locale: LANG=en_US.UTF-8

             VC Keymap: es

            X11 Layout: es

       

      # systemctl restart vmtoolsd.service

       

      Wait until vRops starts collecting Guest|Page in Rate per second metric.

       

      The memory capacity/time remaining graph will be generated just a few minutes later.
