Tenshi is a log monitoring program, designed to watch a log file for lines matching user defined regular expression and report on the matches. The regular expressions are assigned to queues which 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 it, or to send periodic reports.
