How are Group Metrics calculated for sparklines/bar graphs?

pathduck Jan 15, 2015 4:49 AM

Hi,

just something I've been wondering for a long time:

For grouped resources, there are sparklines next to the Resource Measurements, and when you click "see more..." there are bar graphs in the charts.

Just wondering how these graphs are calculated for grouped resources, since normally one would expect line graphs.

So I suspect, these are some kind of 'average' of the resources?

Here is an example, this is a group of six Linux hosts:

Just want to get these questions out of my head on the matter of how these are calculated

Hi Stian,

You are correct in assuming that the sparklines for a group are an average over the resources in the group (over 8 hr period) and the text value being the 'last' value in collection interval.
Probably a better representation is multi-line graph showing all resources individually. However, since there is already a couple paths to multi-line charts now and our focus is on RHQ.next() it will probably remain in its current form.

Thanks Mike - I kind of figured they were averages, just wanted to make sure

I think bars are fine as long as there are averages - we already have line graphs available and I rarely click into the "see more" section anyway.

cheers,
