Data Stewardship Dashboard
The Cloudera Navigator Data Stewardship dashboard captures a variety of information about data, metadata, and user jobs that process the data. The Data Stewardship dashboard provides information and metrics to help you understand the state of the data and data usage, and allows you to visualize trends and averages for a variety of data sources and actions.
Access the dashboard by clicking Analytics and then choosing Data Stewardship on the navigation bar. Specify the source clusters by clicking Source and clicking a cluster name or All Clusters.

Activity Summary
![Navigator Dashboard Activity Summary](../images/nav_dashboard_activitysummary.png)
- The name of the activity
- The number of occurrences for that activity for a time period that you select (daily, weekly, monthly, quarterly, all time)
- A line graph showing activity trends based on the time period that you select
A graphical representation of the time-lapse summary for each activity tile is located at the bottom of the tile. Hovering over a point displays the value for that entity on a particular date. For example, if you select Daily Trend, the number in the graph shows number of occurences for the day so far (since midnight), and hovering over a graph point shows the number of occurrences for that full day as well as the average for the 20-day period represented by the graph.
The Activity Summary area includes the following information:
