Nagios check_log help

[Webster, Stuart SITI-ITDIUR]

Thanks for the extra info, i see how it should work now,
 
but when i try
 
./check_log -F test -O test_log_tmp -q WARNING
I get the same error
./check_log: test: argument expected
 
I have also tried with full path names.
the test log file, just contains random lines, with one line reading WARNING
 
does anyone know what im doing wrong?
 
Thanks
 
Stuart

Yes the -O is necessary for the script to keep track of where it left off.  The plugin is a perl script.  From the in-script comments:
 
# 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.

Hello 
Could some body please help me with this plugin,  and explain what the proper command line arguments should be. 
The documentations says: 
                                      
Usage: check_log -F logfile -O oldlog -q query 
Usage: check_log --help 
Usage: check_log --version 
i presume -F is the log file I want to check, and -q is the string I am searching the log for. 
I have tried 
#./check_log -F test_log -q WARNING 
this just goves the following error                
./check_log: test: argument expected. 
what is the -O for old log?? I only have 1 log file, is the -O necessary? 
the documentation for this plugin is very brief. 
Help Apreciated 
Stuart
