Working with Load Test Tables
When you view the results of a load test run, you can display different panes that provide you with different ways to analyze the data. You can view the data as a graph, to see how it changes over time, or you can view the data as detailed tables. Typically, this type of data is very useful in your first pass when you analyze the performance of your applications under load. To switch to table view, click Tables on the load test toolbar.
In table view, you can view one table at a time. To switch between the different tables, use the Table drop-down list on the toolbar above the table grid. Most numeric values displayed in a table for performance counters are cumulative over the whole load test run. Columns named Last are an exception, and represent the value from the most recent sampling interval.
Note
Columns named Last are available only while a load test is executing. After a load test is completed, these columns are not available.
You can sort most tables by clicking the title of the column that you want to sort on. By default, some tables do not display all available columns. You can add columns to tables, if columns are available. To add columns, right-click the table and then click Add/Remove Columns.
Note
You can copy the data from a table into other applications such as Excel for additional analysis.
The Load Test Tables
The following table lists the tables that are available to analyze load test runs.
| Table Name | Description |
|---|---|
Agents |
Displays summary data for individual agents when you run a load test on a rig with more than one agent. For more information, see The Agents Table. |
Errors |
Displays a list of errors that occurred during the load test run. For more information, see Analyzing Load Test Errors. |
Pages |
Displays a list of pages accessed during a load test run. Some data in this table is available only after a load test has completed. For more information, see How to: View Web Page Response Time in a Load Test. |
Requests |
Displays details for individual requests issued during a load test. This includes all HTTP requests, and dependent requests such as images. For more information, see The Requests Table. |
SQL Trace |
Displays the results of SQL tracing. This table is available only after a load test has completed, and only if SQL tracing was used during the test. For more information, see How to: View SQL Trace Data from a Load Test Run. |

Collecting Percentile Data
Some load test tables can contain additional columns, which include percentile data and response times broken into groups based on network emulation. By default, this data is not collected. To collect this data, in the Load Test Editor, under the Run Settings node, select the specific run setting node to change. In the Properties window, for the Timing Details Storage property, select StatisticsOnly or AllIndividualDetails. For more information, see How to: View Web Page Response Time in a Load Test.
