Add support for calculated metrics to App Insights
I would like the ability to combine two metrics in a third, calculated metric. For example, I might want to create a "Custom Error Percentage" metric that divides custom errors per second by requests per second. I could then alert off an error metric that has been normalized for scale instead of one that's specifically tied to RPS.
We are starting a private preview for derived metrics out of Analytics queries. Please see this item for updates on this:

Besides alerts based on the calculate metric, this feature would be extremely relevant to get to a single dashboard (like the OI dashboard) through which we can drive service reviews etc.
Service availability is typically a combination of GSM availability numbers and some of the performance counters.
