Method readLastLine from AbstractLogParser doesn't take into consideration the actual log message format. If the last line of a log file belongs to a stack-trace, the subsequent parsing of the interval covered by the file will fail with java.lang.IllegalArgumentException: Parsing failed, no data available.
As an example, a file ending with the following logging event will always fail:

The class DefaultLogService iterates over the log files and parses them one by one (parsing a log file is time consuming), these are independent tasks and can be executed in parallel to improve the overall speed.

Add a summary and small examples about the new commands.

Add a new command to filter log files based on a time frame, similar to the current one used for statistics.

The current command output goes straight to the console and can't be easily imported/exported in other formats (json, cvs, xml, etc.).
Revisit the current commands and decide which ones can be improved by adding custom exporters, implementing them afterwards.

Add support for parsing logs.
