check_logfiles is a plugin for Nagios which checks logfiles for defined patterns. It is capable of detecting logfile rotation. If you tell it how the rotated archives look, it will also examine these files. Unlike check_logfiles, traditional logfile plugins were not aware of the gap which could occur, so under some circumstances they ignored what had happened between their checks. A configuration file is used to specify where to search, what to search, and what to do if a matching line is found. License: GNU General Public License (GPL) Changes: A bug in the sticky code was fixed. With the new savethresholdcount option, you can decide whether counters should be persistent or start from zero for each run.
