I want to know how much is each one of my cloud functions spending (break up the total costs on Google Cloud Functions that is shown in my Billing Console). I know I may be able to estimate it probably looking at the metrics and configuration of each function but it would be a hassle to do it one by one (I have a lot of functions).
I couldn't find any way of doing it using the Billing Console alone, it only shows the total cost.
If there was a tool/script it would also be appreciated.
