I am now learning New Relic as a new monitoring tool for me. I used to use signalfx. It’s not clear to me why I cannot use a metric without an aggregate function to create timeseries widget. In signalfx, this is possible. Take for example the simplest metric - cpuPercent. I want to know how this metric has changed over time. Which function should I use? I thought that functions like latest (), average () or median () might work, but they all give different results on the graph (see screenshot). If I want to use timeseries, but am not sure about the choice of an aggregate function, which should I use by default?
