This used to be available in the previous "Billing" tool but the new Server Call Usage report doesn't seem to let you trend over time. I don't don't see where to change the date range unless I go back to Reports.
the issue I have is the new form does not give you the ability to choose which month to download. I created a template that allowed us to trend the last 5 years of billing - and this is now broken. There needs an option to have this for new users to see usage but allow us power users to pull out the raw data in a clean format and trend / classify the data based on business needs
I second this idea. I need to be ale to get a quick monthly view of my server call usage, like int he old billing tab.
If this can't be done on screen, at least allow use to have a granularity option when downloading the report so we can see the data in total or monthly.
