The MapReduce Usage by User report shows metrics on the job activity in your cluster. You can generate a report to view aggregate job activity per hour, day, week, month, or year.
- Click the Start Date and End Date fields and choose a date from the date control.
- In the Report Period drop-down, select the period over which you want the metrics aggregated. Default is Daily.
- Click Generate Report.
For weekly reports, the Date column indicates the year and week number (for example, 2013-01 through 2013-52). For monthly reports, the Date column indicates the year and month by number (2013-01 through 2013-12).
The Activity data in these reports comes from the Activity Monitor; it can include all the data currently in the Activity Monitor database. Note that Activity Monitor data will eventually expire, based on the configuration you have set for Activity Monitor.
