-----------------------------------

             Summary: Create a new alert type that is based on timeseries metrics
                 Key: AMBARI-15766
                 URL: https://issues.apache.org/jira/browse/AMBARI-15766
             Project: Ambari
          Issue Type: Task
          Components: alerts, ambari-metrics
    Affects Versions: 2.4.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
            Priority: Critical
             Fix For: 2.4.0


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.
