Setting the statistics displayed during a run

Lets you set the type of data that you see during a run and the sampling rate for that data, and whether data is collected from all users or a representative sample.

To set the statistics log level:
  1. In the Test Navigator, expand the project until you locate the schedule.
  2. Right-click the schedule, and then click Open.
  3. In the Schedule Contents section, click the name of the schedule and scroll down to the Statistics section.
  4. Set Statistics log level to one of the following:
    Option Description
    None No statistics are displayed during the run, and any report that depend on statistics is not generated. At the end of the run, you see only a Summary report that contains three items: the time the run took, whether the results were on the local computer or, if a remote location, which one, and the status of the run, which is Complete.
    Pages Typically, select this option if you have a large run. You may also want to set a sampling rate.
    All Typically, select this option if you have a small run.
  5. In Statistics sample interval, enter a number and select a time unit. When you run the schedule, the Performance report provides the rate and the number of page attempts per interval, which you set here.
  6. To set a sampling rate, select Only sample statistics information from a subset of users. The number or the percentage that you select is applied to each user group. If you are running user groups at remote locations, the number or percentage that you select is distributed evenly among the remote locations.
    Option Description
    Fixed number of users The number is applied to each user group. Assume that your schedule contains two user groups. One group contains 4 users, and one group contains 1000 users. If you sample 2 users, two users are sampled from each group.
    Percentage of users The percentage is applied to each user group—but at least one user will be sampled from each group. Assume that your schedule contains two user groups. One group contains 4 users, and one group contains 1000 users. If your sampling rate is 10%, one user is sampled from the first group, and 100 users are sampled from the second group. If your sampling rate is 25%, one user is sampled from the first group, and 250 users are sampled from the second group.
