About User Information in Tasks and Task Engine Logs
Task instances in the runtime might include identifying information about user accounts. To ensure proper task operation and effective troubleshooting, Task Engine logs some of the user information, such as user names and IP addresses in the log files of the Task Engine runtime.
Depending on the runtime on which you install Task Engine, information is stored in the IBM My webMethods Server or Integration Server log files. For more information about working with the IBM My webMethods Server log files, see Administering IBM My webMethods Server. For more information about working with the Integration Server log files, see IBM webMethods Integration Server Administrator’s Guide.
