> 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)
