Ambari alerts work natively off of JMX metrics, so if HBase exposes a metric through JMX then you can consume it. We used to do something similar for "dead" RegionServers, but it was determined that a "dead" RegionServer was part of the normal lifecycle and shouldn't have an alert:

I didnt see this metric in the widget creator so I was thinking to create an ambari metrics, and then create an ambari alert on it. I would like to know if there is a way to access to this hbase metric through ganglia or if I need to create a whole new python script to download the metric. As I am new to ambari, I am open to any suggestion.
