Subject [jira] [Created] (AMBARI-996) Expose metrics and properties for UI
Date Fri, 09 Nov 2012 06:02:12 GMT
Tom Beerbower created AMBARI-996:

             Summary: Expose metrics and properties for UI
                 Key: AMBARI-996
             Project: Ambari
          Issue Type: Sub-task
            Reporter: Tom Beerbower
            Assignee: Tom Beerbower

When visiting Ambari's dashboard, there are 3 mini charts which show quick status of HDFS,
MapReduce & HBase services. For HDFS it is the Capacity free/used, for MapReduce it is
time-series data about jobs running, and for HBase is the request counts.

Also need to expose metrics to render Dashboard and Service Summaries.

HDFS service's API needs to output the service's capacity (used/remaining/total) and Block
status - PendingReplicationBlocks, UnderReplicatedBlocks, as these will be needed to show
graphs in the UI.
