Workload Anomaly detection: Anomaly detection of monitored metric.

optional arguments:
  -h, --help            show this help message and exit
  --action {overview,plot}
                        choose a functionality to perform
  -c CONF, --conf CONF  set the directory of configuration files
  -m METRIC, --metric METRIC
                        set the metric name you want to retrieve
  -s START_TIME, --start-time START_TIME
                        set the start time of for retrieving in ms, supporting UNIX-timestamp with microsecond or datetime format
  -e END_TIME, --end-time END_TIME
