Live Optics Agent

Introduction

Welcome to the release notes for Optical Prime enhancements for Live Optics.  We encourage you to follow this page to receive email notifications when this document is updated.

Please make sure you download the latest version of the Live Optics collector to get the latest updates and enhancements

 

New Features/Fixes

 

As part of the ongoing improvements for Optical Prime we are happy to announce a new Virtual Tab in the Optical Prime online viewer.

This new tab, can be accessed by clicking the “Virtual” hyperlink on the top screens selection for the project

The New Virtual tab will display a summary of the Virtual and physical environments for the Hypervisors (only) in your project, and a table with all the Guest VMs information .

Be advised that the information in the Virtual tab is displayed for the entire project regardless to any selection in the Performance tab. For example, if you exluded specific Cluster or Hypervisors in the Performance tab, the information about these Cluster / Hypervisors will still appear in the Virtual tab.

The Virtual tab has 3 main sections

  • Virtual Summary
  • Physical Summary
  • Guest VMs table

Virtual Summary

The Virtual Summary shows the averages and totals for the Virtual environment based on the running VMs in the environment.

 

OP_virtual_tab_2.png

 

It includes the following sections:

  • Averages per VM:
    • vCPUs: Average number of vCPU per VM. This is calculated based on the total vCPUs for the running VMs / total running VMs
    • Active Memory: Average Active memory (GB) per VM.
      Calculate by total Active memory for all running VMs / total running VMs
    • Provisioned Memory: Average Provisioned memory (GB) per VM
      Calculate by total Provisioned memory for all running VMs / total running VMs
    • Memory Oversubscription: Is the ratio of the provisioned memory to the active memory.
      It is calculated Provisioned Memory / Active memory
    • Guest VM Disk Used: Average Guest VM disk used (GB)
      Calculate by total Guest VMs Disk Used for all running VMs / total running VMs
    • Guest Whitespace %: Average % Whitespace per VM. This is the % of unused space per VM that can be reclaimed
      This is calculated based on the % Occupancy per VM. We average the % Occupancy per VM. Since Guest Whitespace is the opposite of % Occupancy we calculate is as 1 – Average % occupancy.
      For example, we have the following environment

mceclip2.png

  • We calculate the average % Occupancy (63%) and then we calculate the Average % Whitespace as (1- Average % Occupancy) = 37%.
  • Guest iSCSI present: If one of the VMs occupies more space than was allocated to it, Guest iSCSI is set to “Yes” otherwise it is set to “No”.
    In the above example (for % Whitespace) since the % Occupancy for VM4 is over 100% (112%), Guest iSCSI Present will be set to “Yes”
    For more information about % occupancy please refer to https://support.liveoptics.com/hc/en-us/articles/360009480413-VM-Occupancy
  • Guest OS Count
    • Windows: How many running VMs run Windows
    • Linux/Unix: How many running VMs run Linux or Unix
    • Other: How many running VMs run an OS that is not Windows or Linux
  • Memory
    • Provisioned Memory: Total provisioned memory for all running VMs
    • Active Memory: Total active memory for all running VMs
    • Active to Physical ratio: The ratio of total Active memory to the hosts physical memory (Active:Physical)
    • Host Consumed Memory: How much memory is consumed on the hypervisors
  • vCPU
    • vCPU: Total of all vCPUs for all running VMs
    • vCPU per CPU ratio: the ratio of vCPU per Sockets (socket:vCPU)
      This is calculated based on the average vCPUs per Socket on each host and then averaging the vCPU per Socket.

For example, we have the following environment

mceclip0.png

  • We calculate the average vCPU per Socket as, the total vCPU per socket for each server (26.25 vCPUs) / by total hosts (5) = 5.25 vCPU per Socket (1:4.45)
  • vCPU per Core ratio: the ratio of vCPU per Core (Core:vCPU)
    This is calculated based on the average vCPUs per Core on each host and then averaging the vCPU per Core.


For example, we have the following environment

 

mceclip3.png

  • We calculate the average vCPU per Core as, the total vCPU per Core for each server (6.56 vCPUs) / by total hosts (5) = 1.31 vCPU per Socket (1:1.11)
  • Capacity
    • Virtual Disk Used: the total of Virtual Disk Used for all running VMs
    • Guest VM Disk Capacity: the total of Guest VM Disk Capacity for all running VMs
    • Guest VM Disk Used: the total of Guest VM Disk Used for all running VMs
    • Reclaimable: all the reclaimable capacity based on Virtual Disk Used - Guest VM Disk Used.

 

Guest VMs table

The Guest VMs table displays the information of all the VMs in the environment, like the information in the “Performance View” in the Optical Prime online viewer

 

OP_guest_VMs.png

 

The title shows the total VMs and total running VMs. In this example, we have 99 Running VMs out of 118 VMs (99/118).

The Guest VM table displays the following information

  • IsRunning: an indication if the VM is running or not
  • Guest VM name: the name of the VM
  • Guest VM OS: An icon for the OS (Windows, Linux or Other)
  • Guest VM Disk Capacity
  • Guest VM Disk Used
  • Guest VM % Occupancy: the % of occupied space on the VM based on the space allocation allowed for the VM
    For more information about % occupancy please refer to https://support.liveoptics.com/hc/en-us/articles/360009480413-VM-Occupancy
  • Used Memory
  • Provisioned Memory
  • Virtual CPUs
  • Platform: VMware, Hyper-V or Other
    * See “Host Platform(s)” explanation below for more information about the Platform.

Physical Summary  

The Physical Summary shows the totals for the physical hosts (Hypervisors) in the environment

    Hi - would be useful if there was a simplified explanation or call out next to items that can be hovered over with mouse e.g. Active memory vs. Provisioned but in lay mans terms so that when going over the Live Optics run with the customer it makes it easier for them to follow
