+# NAME:         check_timed_logs.pl
+#
+# AUTHOR:       Gerd Radecke
+#
+# COMMENT:  Script searches a text file for the appearance of a given RegEx within a given time period.
+# 			Using additional parameters you can adjust: Time string format,
+#			time string position, number of pattern matches required to be "successful".
+#
+#           Return Values for NRPE:
+#           	OK - There are only 0 instances of $pattern in the last $interval minutes (0)
+#           	CRITICAL - There are $hits instances of \"$pattern\" in the last $interval minutes (2)
+#           	WARNING - There are $hits instances of \"$pattern\" in the last $interval minutes (1)
+#           	UNKNOWN - There were no files matching the passed filename (3)
+#
+# REQUIRES: 	perl-Time-Piece perl-File-ReadBackwards
+#				ON RHEL-based systems you can run: yum install perl-Time-Piece perl-File-ReadBackwards
+#
+# CHANGELOG:
+# 1.0 2013-02-19 - initial version
+# 1.0.1 2013-02-27 - fixed false variable reference
+# 1.0.2 2013-10-07 - integrated threshold comparison fix by Christoph Tavan - thanks ;)
+# 1.0.3 2019-12-23 - Added --reverse flag to check for presense of lines within last $interval - drewn3ss
+# 1.0.4 2019-12-30 - Updated time_pattern default to match ubuntu syslog timepattern
