  • Thanks, Sascha.  I have the team looking into this one.  

  • What we observed is that there is a behavior difference between on box vs historical reporting.  The dashlet is intended to show an average utilization over the past 24 hours so that you have an understanding of how utilized an appliance on average.  The report below will show utilization peaks and dips over that time range.   If we include the text 'average' in the dashlet, I think that will help clear any confusion on the behavior.  The dashboard also does not yet reflect "Last 24 hours" at the top, which will also serve to reinforce that point.  

  • Hi Rob,

    I may not be understanding the explanation above correctly.

    I just got in the EAP and let my device get some data up into Central.  I too am showing the same with respect to memory usage.  I know that my memory usage has been roughly 60% since I installed v18 yet the report shows 6% and 6.0 when you click the bubble.

    Are you saying this is expected?  Or it should show the average over the reporting period.  So it's been reporting for 2 hours but we are going to average that over a 24hr period and that's where the 6% is coming from?

  • The memory and CPU dashlets will show the average over the last 24 hours.   If that seems off, can you share the table of the memory usage over the past 24 hours from the dashboard?  Also, show the memory usage on XG over the same time range.
