I would like to know what uuid, guid, client id and user id means on the log.

please refer to the JENNIFER manual for more detail.
Uuid: unique ID of transaction
Guid: a key combining multiple transactions as a group. (no default value.)
Client id: client unique id that will be managed by cookie.
User id: id that users use in a daily working environment. (no default value. You need to apply a setting.)
