New Charts - Top CPUs in %

roga

Hi @all,

can someone explain me, why there is a difference between the lines?

This is the same node and its the same chart:

Classic chart:

Modern chart:

Why is the cpu load not the same? Maybe a bug in the modern chart?

It is deffinetly the same node and the same timeframe.

Thanks

More granular data in the second chart, the first one is averaging the data to the intervals. From counting the number of spikes I assume you have 30 minute intervals defined in the first chart where the second is displaying every datapoint for every cpu at whatever your statistics interval is, default 10 min.

I find it somehow confusing. as soon as I open the chart in the Perfstack, the utilization looks completely different.

Yesterday I saw a post indicating there might be a bug where the perfstack view has the charts using area chart mode and if you use the widget it is using stacked area view. With that in mind and comparing the numbers in your screenshot certainly makes them look like they are stacking. I know it was submitted as a bug so it'll probably sort itself out in the next release, but feel free to throw a ticket into support to draw attention to it.
