Since it is possible for there to be a large amount of data in a given log file or series
of log files, Logtool gives the user a set of formatting and display filters that enable
the user to select only those log entries that are of interest for formatting or viewing.
The formatting filter is used to selectively format only raw entries that the user is
interested in and the display filters are used to selectively display the formatted or
raw entries that the user is interested in.
For example, a user could specify that only log entries for disk drives should be
formatted which would result in a formatted log file containing only disk entries.
Later, when displaying the entries, the user might decide to display only entries for
Hard disks, or only disks on a certain path, etc.
The following diagram outlines the general flow of data between the STM logger,
log files and Logtool. The thick solid arrows in the diagram represent data flows and
the thin solid arrows show how the various filters are generated. The dashed boxes
represent processes or logical blocks of code. For example, the Logtool box and the
STM Logger box represent separate processes.
