8.4 STI recording and playback
STI measures how users might experience a Web site in the course of
performing a specific transaction, such as searching for information, enrolling in a
class, or viewing an account. To record a transaction, you use STI Recorder,
which records the sequence of steps you take to accomplish the task. For
example, viewing account information might involve logging on, viewing the main
menu, viewing an account summary, and logging off. When a recorded
transaction accesses one or more password-protected Web pages, you create a
specification for the realm to which the pages belong. After you record a
transaction, you can create an STI playback policy, which instructs the STI
component to play back the recorded transaction and collect a range of
performance metrics.
To set up, configure, deploy, and prepare for playing back the first STI recording,
the following steps have to be completed:
1. STI component deployment
2. STI Recorder installation
3. Transaction recording and registration
4. Playback schedule definition
5. Playback policy creation
Please note that the first two steps only have to be executed once for every
system that will be used to record synthetic transactions. However, steps 3
through 5 has to be repeated for every new recording.
