Jaynir,

You can do it with Performance monitor by choosing Database-Log growth Counter and log growth event  in SQL Profiler. Well DBCC SQLperf  doesn't give how it is growing . You can query sys.master_files to object size and growth. Yes, there are many third-party tools to monitor log growth and read log file like Luminent Log Explorer. We use MOM to monitor  log growth  which sends email to DBA if it is consuming huge space.
