Notes on the syntax

  • Valid delimiters for the entries are "spaces".

  • The following applies to the file name of a file DB:

    • The file name begins with "cpuX" (where X=1, 2, 3 or 4);

    • "cpuX" must first be defined in the rack/slot assignment;

    • Length: Maximum of 64 characters (including "cpuX");

  • Maximum of 100 entries;

  • Permitted characters: Letters "A-Z, a-z"; numbers "0-9", "_", "."

    Note

    Keep to the notation (lower case for "cpu" and no leading spaces at the start of the row). Otherwise, the files will not be recognized.

    The tabulator is not permitted as the delimiter.
