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 the database. These elements are ODB links allowing the user to extend the list with any parameter in the ODB database. This logger mySQL option may replace or complement the runlog.txt functionality of the ana_end_of_run() function from the analyzer.c.

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

Example /Logger/Runlog/SQL subtree
