             Summary: Review (and adjust) new HDFS script alerts response text
                 Key: AMBARI-15999
                 URL: https://issues.apache.org/jira/browse/AMBARI-15999
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.4.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Critical
             Fix For: 2.4.0


Review the response text for new SCRIPT alerts for HDFS (the list below). The text currently has some issues (units being incorrect for example). I also suggest removing the leading "WARNING." or "CRITICAL." text as that is unnecessary.

All use the same script, so the change is isolated. But reviewing the various alerts that use the script will give some context. 

HDFS/2.1.0.2.0/package/alerts/alert_metrics_deviation.py


{code}
WARNING. Percentage standard deviation value 28.42% is beyond the warning threshold of 20.00% (growing None seconds to 0.13 seconds)
