I would like to setup some hourly email alerts for some services (Flume, Impala, etc) with the summary of the hours metrics. For example, put successes or failures in the part hour of Flume service channels, etc.
Is there a way to set these up? Any documentation on what all metrics are available for each service?

Alerts only come from alertable events that transition state from non-alertable to alertable. Cloudera Manager does not provide any means by which to schedule regular reports.
In order to pull metrics to for use in other tools that may be able to do the sort of metrics emails you want, you could look into leveraging the Cloudera Manager API:
Here is a list of metrics for the services:
Depending on your needs, you may also be able to leverage hadoop metrics2 that can be used in Ganglia and other tools:
