tenshi
tenshi (formerly wasabi) is a log monitoring program designed to watch a log file for lines matching user defined regular expressions and report on the matches. The regular expressions are assigned to queues that have an alert interval and a list of mail recipients. Queues can be set to send a notification as soon as there is a log line assigned to them, or to send periodic reports. Additionally, uninteresting fields in the log lines (such as PID numbers) can be masked with the standard regular expression grouping operators ( ). This allows cleaner and more readable reports. All reports are separated by hostname and all messages are condensed when possible.

Recent releases
- 14 Mar 2008 10:02
Changes: The option includedir now skips dotfiles. The PID file is now created in debug, profile, and foreground modes. An incorrect UID check not handling the root user has been fixed. Buggy time_to_die, buggy tail_multiple option parsing, empty report sending if the filter program returns no output, and a bug regarding unmatched subpatterns have been fixed. This release dies before the pipe if tail_file is not readable, which prevents an fd leak. IO::Select has been replaced with IO::BufferedSelect, which fixes parsing delay of buffered lines.
