Customizing Online Graph Settings - LoadRunner

You can modify the following online graph settings while a load test is running from the Remote Performance Monitor:

• graph scale
• graph refresh rate
• graph configuration measurements

The changes to the default settings apply only to the current run and are not saved for future runs of the load test.

Scaling Graphs

You can modify the scale of a measurement the relationship between the y-axis and the graph’s actual value. The x-axis represents Elapsed Time and cannot be adjusted. By default, LoadRunner uses the Auto option, which automatically sets the most suitable measurements for displaying the graph.

To scale the large graphs:

1. In the y-axis value section below the large graphs, select Set to, type a value in the box, and click Refresh Graphs. The graph is redrawn with the specified value as the upper limit of the y-axis.
2. To view the graph scaled normally, select Auto and click Refresh Graphs.

To scale the small graphs:

1. Click the Scale button located above the small graphs. The Scale Graphs dialog box opens. You can change the y-axis measurement of the small graphs in positions three, four, and five as shown in the Select Graphs window.
   

   

2. To use a different scale, select Set to, and type a value in the box.
3. To view the graph scaled normally, select Auto.
4. Click OK to close the Scale Graphs dialog box. The graph is redrawn with the specified value as the upper limit of the y-axis.

Refresh Rate

By default, graphs on the Remote Performance Monitor page are refreshed every five seconds. You can use the Auto-Refresh option to change the default refresh rate. If you increase the refresh rate, the graphs are refreshed less frequently. In a large load test, it is recommended to use a slower refresh rate for the small graphs. This enables you to avoid problems with CPU resource usage.

To modify the default refresh rate:

1. Click the Refresh button located above the small graphs. The Refresh Rate dialog box opens. By default, the refresh option is enabled to automatically refresh all graphs at 5 second intervals. To disable the auto-refresh option, select the Do not refresh check box.



2. Select a frequency for refreshing the large graphs and small graphs.
3. Click OK to modify the auto-refresh rates and return to the LoadRunner Remote Performance Monitor page.

Note: To refresh the graphs and the legends immediately, click Refresh

Graphs.

Configure Graph Measurements

You can customize graphs to show, hide, or highlight selected graph measurements.

To configure graph measurements:

1. Click the icon at the top of the large graph pane to configure the graph’s measurements. The Configure Graph Measurements window opens.
   

   

2. Select the Show check box to show a measurement on the graph. By default, all graph measurements are shown on the graph. To remove a measurement from being displayed on the graph, clear the Show check box. To highlight a measurement in bold on the graph, select the Bold check box. Select the Select/Deselect all check box in the Show column to display all measurements on the graph. Clear the Select/Deselect all check box to remove all measurements from the graph.
   To highlight all measurements in Bold on the graph, check the Select/Deselect all check box in the Bold column. To remove the bold highlights, clear the Select/Deselect all check box
3. Click OK to close the Configure Graph Measurements window. The new graph configuration settings appear on the refreshed graph.
