+# Log file pattern detector plugin for Nagios
+# Written by Ethan Galstad (nagios@nagios.org)
+# Last Modified: 07-31-1999
+#
+# Usage: ./check_log <log_file> <old_log_file> <pattern>
+#
+# Description:
+#
+# This plugin will scan a log file (specified by the <log_file> option)
+# for a specific pattern (specified by the <pattern> option).  Successive
+# calls to the plugin script will only report *new* pattern matches in the
+# log file, since an copy of the log file from the previous run is saved
+# to <old_log_file>.
+#
+# Output:
+#
+# On the first run of the plugin, it will return an OK state with a message
+# of "Log check data initialized".  On successive runs, it will return an OK
+# state if *no* pattern matches have been found in the *difference* between the
+# log file and the older copy of the log file.  If the plugin detects any 
+# pattern matches in the log diff, it will return a CRITICAL state and print
+# out a message is the following format: "(x) last_match", where "x" is the
+# total number of pattern matches found in the file and "last_match" is the
+# last entry in the log file which matches the pattern.
+#
+# Notes:
+#
+# If you use this plugin make sure to keep the following in mind:
+#
+#    1.  The "max_attempts" value for the service should be 1, as this
+#        will prevent Nagios from retrying the service check (the
+#        next time the check is run it will not produce the same results).
+#
+#    2.  The "notify_recovery" value for the service should be 0, so that
+#        Nagios does not notify you of "recoveries" for the check.  Since
+#        pattern matches in the log file will only be reported once and not
+#        the next time, there will always be "recoveries" for the service, even
+#        though recoveries really don't apply to this type of check.
+#
+#    3.  You *must* supply a different <old_file_log> for each service that
+#        you define to use this plugin script - even if the different services
+#        check the same <log_file> for pattern matches.  This is necessary
+#        because of the way the script operates.
+#
+# Examples:
+#
+# Check for login failures in the syslog...
+#
+#   check_log /var/log/messages ./check_log.badlogins.old "LOGIN FAILURE"
+#
+# Check for port scan alerts generated by Psionic's PortSentry software...
+#
+#   check_log /var/log/message ./check_log.portscan.old "attackalert"
+#
+
+# Paths to commands used in this script.  These
+# may have to be modified to match your system setup.
+# TV: removed PATH restriction. Need to think more about what this means overall
