check_file

check_file is a nagios plugin for checking a timestamp on a file. It uses
the mtime value and localtime on the server and compares the difference of
those against a given critical and warning value.

It is written in C and has been tested under Linux. It should be easily portable to other UNIX and without too much trouble to any POSIX OS.

-p must be given on the command line and is the path to the file or directory to monitor.

-e will only check for the existence of the file. This can not be used with -w and -c.

-w is the warning threshold. If you give -w 60 it will warn if the file is
older than 60 seconds. thresholds are only in and will only ever be in
seconds.

-c is the critical threshold. If you give -w 60 -c 65 it will warn from 60
seconds until 64 seconds then be critical from 65 seconds onward.

-i will invert the options. used with -e it will check for the non-existence of the file. Used with -w and -c it will check the file is NOT newer than the times given.
