The midas documentation has moved. See [https://midas.triumf.ca/docs/develop/reference/reference/programs/#mlogger mlogger] on the Programs and options page and [https://midas.triumf.ca/docs/develop/features/storing_data/data_logging/ Data logging: overview] for the new documentation about the mlogger program.
 
The MIDAS Logger, <span style="color:darkcyan;">''mlogger''</span>, is the main application that collects data from one or more [[frontend]]s under certain conditions and stores them onto a physical device such as disk or tape. It also acts as a history event collector and can also store data in a mySQL database.
The features and customization of the logger utility are fully described in the section [[Logging in MIDAS]] .
 
    Arguments
        [-h ] : help
        [-e exptname ] : experiment name (see [[odbedit]] - ODB Editor and run control utility)
        [-D ] : start program as a daemon (UNIX only).
        [-s] : Save mode (debugging: protect ODB).
        [-v] : Verbose (not to be used in conjunction with -D).
    Usage
    >mlogger -D
 
Notes
    <span style="color:darkcyan;">''mlogger''</span> creates the [[/Logger ODB tree]] with default values the first time it is run
    The <span style="color:darkcyan;">''mlogger''</span> application requires an existing [[/Equipment tree]] in the ODB
    Once the <span style="color:darkcyan;">''mlogger''</span> is running, you should be able to monitor its state with [[mstat]] or with [[mhttpd]].
