This graph shows the sum of the values for user-defined data points throughout the load test scenario run.
This graph typically indicates the total amount of measurements which all Vusers are able to generate. For example, suppose only a certain set of circumstances allow a Vuser to call a server. Each time it does, a data point is recorded. In this case, the Sum graph displays the total number of times that Vusers call the function.
Elapsed time since the start of the run.
The sum of the recorded data point values.
In the following example, the call to the server is recorded as the data point user_data_point_val_1. It is shown as a function of the elapsed scenario time.
