Creating the /logger tree

The /Logger ODB tree is created when the mlogger utility is started for the first time. The keys will be filled with default values which users may change as required to customize their experiments. See keys in the ODB /Logger tree for more information on each key.

Purpose

Most of the keys in the /Logger ODB tree are used to customize logging of the data. There are also keys to customize the Messaging system. The /Logger tree also may contain optional keys /Logger/Elog dir and /Logger/History dir relevent to storing the History and Elog data files.

The optional subtree /Logger/SQL is used when logging to a mySQL database.

Example

The following example shows a typical /Logger ODB tree obtained using the odbedit ls command. See keys in the ODB /Logger tree for more information on each key.
