Live Optics Agent



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

A new option is available during LIVE and SIOKIT collection (Fig 1) that allows the user to capture individual performance data on a per VM bases.  The VM performance data checkbox (Fig 2) has been added to the “Add Remote Server” selection window while running a LIVE or SIOKIT assessment.  This checkbox is preselected when a vCenter assessment is made. When this checkbox is selected then Live Optics will conduct 2 concurrent assessment:

  1. Normal Live Optics Assessment based upon the duration selected (10 min, 4hr, 8hr, 12hr, 1 day…7 day).  This assessment collect upcoming or future data
  2. A VM performance run that is estimated 3 to 5 sec per VM will be needed to complete the VM Performance collection run.   This assessment collects up to the last 24hour of data that is stored in the vCenter.  The length of historical data recorded is set by the vCenter administrator.


The VM Performance will run in parallel (Fig 3) to the normal Live Optics collection run and both must complete for the overall assessment to be finished.  Once the assessment is complete the user will need to log on to the portal and select “Download Excel” from the pull down menu. This will result is a ZIP file download that will consist of 2 excel sheets (Normal Live Optics Excel & VM Performance excel file).
