> There are a few requirements around creating alerts based on the time-series data stored in AMS. They fall in the the general category of:
> identify a metrics (name of the metrics, app name)
> - identify a window (e.g. last 10 minutes, last 1 day)
> - get the data points
> - add them up, or
> - compute average, or
> - compute standard deviations, or
> ...
> - compare the value to a threshold
> - emit an alert if needed (WARN, CRITICAL, etc)
> We should also allow for alerts based on multiple metrics but there is no ask for such a capability. Just something to keep in mind while designing.
> It seems general enough that we should define an alert type that can be instantiated by services to define specific alerts. Users can add additional alerts if they so choose.
