             Summary: Enable Periodic metrics by default
                 Key: IMPALA-12385
                 URL: https://issues.apache.org/jira/browse/IMPALA-12385
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Kurt Deschler


Periodic metrics currently require user to set resource_trace_ratio and in many 
cases to restart backends with different periodic_counter_update_period_ms 
settings. Changing the defaults and tuning the collection mechanisms will make 
metrics always available and they can be turned back off if not desired.
