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.

  1. In the Report Period field, select the period over which you want the metrics aggregated. Default is Daily.
  2. Click Generate Report to produce the resulting 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; 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.
