             Summary: Set default minute based host level aggregation to 2 minutes
                 Key: AMBARI-10076
                 URL: https://issues.apache.org/jira/browse/AMBARI-10076
             Project: Ambari
          Issue Type: Task
          Components: ambari-metrics
    Affects Versions: 2.0.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 2.0.0


- Interval of 5 minutes leads to larger volume on reads and the data might not be coming from the block cache.
- Observed with 400 node testing that setting this to 2 minutes improves the cache hit ratio and the thread completes in 30 seconds.
