sysutils/logfmon 1.2 OpenBSD

The logfmon daemon monitors a set of syslog log files and matches each new entry against the rules defined in its configuration file. Each rule may be tested against entries from a single file, a set of files or from all files. Depending on the rule, a command may be executed or the entry may be ignored. All unmatched messages are batched together and mailed every 15 minutes, or whatever alternative time is specified in the configuration file.
