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 the monitoring system 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 the +# monitoring system 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. +# +# 4. This plugin does NOT have an understanding of logrotation or similar +# mechanisms. Therefore bad timing could lead to missing events +# +# +# 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.
