问题
These aren't custom metrics I'm trying to add just the existing GCP metrics.
How do I add 2 metrics together in a Stack driver time series?
I have two different metrics and I want to sum them so I see a single line- also I'd like to be able to alert on this summed metric too. Is this possible?
Again I'm not shipping metrics to stack driver I'd doing this with existing metrics already there.
