TODO

./doc/Events log4j Parser TODO.docx.

Usage

lg [query] [command] [command options] <log-file1> [log-file2 ...]

The command is optional.

When the command is missing, the implied command is "output", which works as described here:

output

Unless output filtering options are used, the events are displayed in their raw format, which is how they appear in the original log.

Commands:

• help
• version
• output
• describe - displays a description of the events produced as the result of the parsing.
• time-gaps - identify time gaps in the log
• count (-c) - display the number of events that match the query.
• exclude (-x) - filter out the events that match the query, and only display those that do not match. This command is equivalent with the grep --invert-match (-v) option.
