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.
