The Ajax Dashboard is divided into three areas:
- A summary, with a waterfall graph of the entire load sequence. To see details for each set of data, use the Trends/Details checkboxes.
- Two sections of Trends/Details across time for the main performance categories:
- Overall performance
- Time used by the server to process the request through the browser's incorporation of the data into the HTML document
Ajax Dashboard Summary Section
This section provides a quick overview of the item's performance over time.
Key performance indicators—End User Response Time, Load, Cache Hits and Views with Errors—across the period selected in the timeframe dropdown from the upper-right side of the GUI—are displayed across the top of the summary area.
A waterfall graph displays the average times needed for each aspect of the Ajax request load process.
For more information on what each of the metrics measures, hover over its name on the left side of the graph. A popup appears with a definition. See the graphic above for an illustration. See Browser RUM Metrics.
To see detailed breakouts of the data behind the graph, check the Trend/Detail checkbox by the data group in which you are interested.
