View and customize online monitor graphs
This topic describes how to open monitor graphs and customize their display.
Before you begin, the relevant monitoring environments must be configured. For details, see Set up a monitoring environment.
Note: In version 2020, the Online Monitor Graphs user interface changed significantly. If you prefer to use the old interface, select View > Use New Online Dashboard. Clear this menu option, and restart LoadRunner Professional. Note that the following online help topics describe the new interface, which is used by default.
Adding monitor graphs to the display
By default, LoadRunner Professional displays the following graphs in the graph display area of the Run tab:

Runtime Graphs > Running Vusers

Transaction Graphs > Transaction Response Time

Web Resource Graphs > Throughput

Web Resource Graphs > Hits per Second
To add additional graphs, expand the category nodes in the Graphs tree on the left of the Run tab. Select a graph's checkbox to add it to the graph display area on the right.
The graph display area can contain up to 12 graphs at the same time.
Tip: If the Graphs tree is not displayed, click the Expand arrow (>) on the left side of the graph display area. To hide the graph tree, click the Collapse arrow (<) on the right side of the graph tree.
Viewing graph measurements
To expand a graph and show its measurements, perform one of the following:

Rightclick a graph in the Graphs tree, and click Details.

From the graph display area, doubleclick a graph, or select a graph and click the Maximize graph button. To restore the previous view, doubleclick the maximized graph or click the Minimize graph button.
Managing the Graphs tree (left pane)
Rightclick a checked graph in the Graphs tree, and select one of the following menu commands:
Settings 
Configure what a graph displays. For details, see Configuring graphs. 
Duplicate 
Make a copy of a graph. 
Rename 
Rename a graph. 
Delete 
After duplicating a graph, click to delete the copy. You cannot delete an original, outofthebox graph. 
Managing the graph display area (right pane)
Select a graph in the graph display area, and select one of the following menu commands:
Settings 
Configure the graph settings. For details, see Configuring graphs. 
Duplicate 
Make a copy of a graph. To rename a duplicated graph, click the duplicated graph's title and type the new name. 
Delete 
Enabled only for duplicated graphs. After duplicating a graph, click to delete the copy. You cannot delete an original, outofthebox graph. 
Pause / Continue 
Select Pause to pause a graph during a scenario run. To resume, select Continue. When resumed, the graph displays the data for the paused period as well. 
Merge Graphs 
Combine the results of two graphs from the same scenario into a single graph. The merging enables you to compare several different measurements at once. Select Merge Graphs, and then drag the current graph on top of another graph. A new graph is created, containing the measurements of both of the original graphs. 
Export to HTML 
Create an HTML version of the selected graph for offline viewing at a later stage. Note that LoadRunner Professional generates a snapshot image of the selected graph. For optimal results, enlarge or maximize a graph, and then export it to HTML. To export all the graphs in the display area, click the Export Graphs to HTML button in the upper right corner. (This is enabled when you are showing multiple graphs, and not one graph expanded.) 
Add Measurements 
When there are measurements available to add to a graph, this enables you to select measurements to display. Note that you can also click on the Add Measurements button inside the graph itself. 
Tip: To reorganize the graph display area, drag and drop graphs to the required location.
Configuring graphs
You can customize the type of graph display, and what to display on the xaxis and yaxis.

To configure a selected graph, click Settings in the graph's upper right menu.

To configure all graphs, click the Graphs Settings button in the upper right corner of the graph display area.
In the right pane of the graph display area, define the following:
Bar Values Type 
If the Bar display type is selected, determines the type of value that will be displayed in the bar graph: Average, Last Value, Minimum, Maximum.

Description 
Displays the graph's default description.

Display Type 
The type of graph displayed: line graph or bar graph.
By default, each graph is displayed as a line graph.
Note: On legacy online only: For the Network Delay graph, if you rightclick the graph and select View Segments, you can view the network segments of the graph as an area graph or a pie graph. 
Graph Time 
Indicates the scale for a graph's xaxis when it is timebased. A graph can show 60 to 3600 seconds of activity. To see the graph in greater detail, decrease the graph time. To view the performance over a longer period of time, increase the graph time. The available graph times are Whole Load Test, Last 60 seconds, Last 180 Seconds, Last 600 Seconds, and Last 3600 seconds.

Network Delay View 
On legacy online only, in the Network Delay Time graph:

Refresh Rate 
The interval at which the graph is refreshed with new data. By default, the graph is refreshed every five seconds. If you increase the refresh rate, the data is refreshed less frequently.
Note: In a large load test, it is recommended to use a refresh rate of three to five seconds. This enables you to avoid problems with CPU resource usage. 
Time 
Specifies how the graph displays the time (in seconds) on the xaxis:
Note: If no step is running, the clock time is displayed. 
YAxis Scale 
Displays graphs using the selected yaxis scale:

Configuring measurement settings
You can customize the appearance and scale of measurements in a graph, and select whether they should be displayed in the graph or hidden from the graph.
In the Run tab, rightclick a measurement in the graph or legend, and select Settings. You can modify the following:

Color. The color assigned to the selected measurement.

Scale. The relationship between the yaxis and the graph's actual value. (Default: Automatic). For example, a scale of 1 indicates that the measurement's value is the value of the yaxis. If you select a scale of 10, you must multiply the yaxis value by 10 to obtain the true value of the measurement.

Automatic. Automatically scales the measurement by calculating the best ratio for displaying the graph. For some graphs, this option is not available.

Visibility: Show / Hide. The resource selected in the legend is shown/hidden in the graph. By default, all resource measurements are shown in the graph. To show only a selected measurement, rightclick the measurement, and select Show Only Selected.

Keep the legend sorted. If you select this option, the order of measurements changes in real time based on the selected column. For example, if you click the Max column to sort by the maximum value, the measurements will always be listed from the highest to the lowest, based on their Max column value.
