ReadyAPI stores information about simulated virtual users and simulated requests in virtual API transaction logs. You can find this information on the Transaction Log page.
To configure the virtual API transaction options:
Click on the ReadyAPI toolbar.
Select Virtual Service Transactions in the left part of the ReadyAPI Preferences window.
The Transaction logs to keep option allows you specify the number of transaction logs to store. When the number of transaction logs exceeds the limit, the oldest logs are deleted.
