XCP-NG - XO Stats - Contradictory Readings

Hi Guys,

I’m trying to set-up alerts in XO’s perf-alert pluggin based on CPU usage of my hosts. I’m looking at taking based readings from the stats tab for each host to determine an average. However, I’m getting contradictory readings. If I select the “last 10 mins” filter, it shows that one vcore is running just under 75%

However, if i do this over “the last week” if shows different results.

Perhaps I’m not understanding this stats page clearly enough. Don’t know if I should set my threshold at 85% or 50%

Any comments welcome.
