Activity Reports
The following report shows metrics on the job activity in your cluster.
MapReduce Usage by User
This produces a tabular report that you can use to view aggregate job activity per hour, day, week, month, or year.
- In the Report Period field, select the period over which you want the metrics aggregated. Default is Daily.
- Click Generate Report to produce the resulting report.
For weekly reports, the Date indicates the year and week number (e.g. 2011-01 through 2011-52). For monthly reports, the Date indicates the year and month by number (2011-01 through 2011-12).
The Activity data in these reports comes from the Activity Monitor; they 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.
