             Summary: Integrate Prometheus into Ozone Recon.
                 Key: HDDS-3006
                 URL: https://issues.apache.org/jira/browse/HDDS-3006
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
          Components: Ozone Recon
    Affects Versions: 0.5.0
            Reporter: Aravindan Vijayan
            Assignee: Attila Doroszlai
             Fix For: 0.5.0


The goal of Recon is to provide a window into the state of the Ozone cluster. Given that it will have OM and SCM metadata,  the next step is to get monitoring information from the ozone components. This will help Recon obtain more dynamic information about the active pipelines. Since all the ozone components are already compatible with pushing metrics to a prometheus end point, we can go ahead with that as the metric store. 

The tasks involved in this JIRA are :
* Recon deploy should bring in a prometheus instance with it.
* Recon start/stop will manage the prometheus start/stop.

Since this instance is only expected to be used by Ozone, we don't need to have it fully customizable. A default prometheus config file can be included that can be used by the prometheus instance.
