The MIDAS logger (mlogger) is able to record information in an ASCII file.

Under two dedicated subdirectories Links BOR and Links EOR , predefined links exist which will be used at begin-of-run (BOR) and end-of-run (EOR) respectively for storing parameter values into an ASCII file. These elements are ODB links allowing the user to extend the list with any parameter in the ODB database.

The following example shows a /Logger/Runlog/ASCII tree as created by mlogger. See ODB /Logger/Runlog/ASCII subtree for an explanation of the meaning of each key.

Example /Logger/Runlog/ASCII subtree

[local:midas]Runlog>ls -lr ASCII
