Azure Storage Account Metrics - Add Percent Used/Free as a Metric

[ssheldon]

Currently, Azure storage account metrics include used space as a raw number. We can set metric events for these then like: if used space exceeds 100gb, trigger a problem.

The idea I'm submitting is to grab percentages in addition to the raw value, so we can alert on, say, 90% full. It's more sustainable than doing it by raw sizes, since the sizes of the different storage accounts can vary and can increase too.

I think this is a good idea; however, Azure doesn't even have a "% used", or even a "total capacity" that could be used to do a calculation using (used/total)*100 to get a "% used".  See image below.
