Usage of Irate and increase function in kepler Dashboard

[MahimaK20]

Hello All,

The kepler dashboard is using irate and increase functions for the power consumption in the cluster.
I have a query on why are we using irate function for calculating Total Power Consumption (W) in Namespace and increase function for Total Power Consumption (kWh per day) in Namespace ?
What is the significance of using two different functions? Also, can we use rate function instead of irate and increase?

I believe this question has been raised before. The irate works with volatile data better than rate, but I think this is more of an implementation choice

In essence, rate() shows the average change over a period, while irate() reveals how fast something is changing. The smoothing effect with rate() becomes more apparent when looking at a longer time window. As we want to show immediate changes (power fluctuation), we use irate().
