readable output based on message resources stored in a database.

parselog reads a windows event log (.evt file) and combines that
information with messages templates and other resources stored in a
pre-generated database. This is then printed to stdout in a comma-
separated values (CSV) format. The database must be created by
This is the directory where the database is stored. Currently,
the actual log files from the original system are also stored in
this directory tree.
This is the windows name for the log. By default windows has the
But others may have been created by third party software. Use
the -l option to print a list of all available log types. (The
log names are case-sensitive.)
-? Prints a basic usage statement.
--help Same as -?.
-l Log list mode. Lists the logs available in the specified
-m Meta information mode. Lists meta information stored in the
header of the specified log file. Does not print any actual log
records. (Format of output in this mode is still subject to
-v Verbose mode. Prints status messages to stderr, which can be
helpful for debugging.
-h Prints a header row at the top of the CSV output containing
labels for each column. (This is the default behavior.)
-H Disables the printing of a header row. This is useful when
grokevt-parselog is used in a script.
-u Enables the UTF-8 output of some strings. This can be dangerous
on terminals that are not configured to support UTF-8.
-U Disables the use of UTF-8 for output. Unicode strings are
instead converted to UTF-8 first, and then any remaining non-
ASCII characters are quoted. (This is the default behavior.)
To list all available logs types stored in ’~/example.grokevt’:
grokevt-parselog -l ~/example.grokevt
To read the ’Application’ log from the database stored in
’~/example.grokevt’ and print it to stdout:
grokevt-parselog ~/example.grokevt Application
To read the ’System’ log from the database stored in
’~/example.grokevt’ and print it to stdout without a header, and with
verbosity turned on:
grokevt-parselog -v -H ~/example.grokevt System
Probably a few. This script has not been extensively tested with some
The file event log file format is pretty well understood and
implemented, but some diabolical wrapped, dirty, or fragmentary logs
may not be correctly parsed.
Unicode support is currently limited. Any suggestions on how to better
handle unicode output would be appreciated.
