Usage: check_uptime -w <warn> -c <crit> [-v]

   Checks the uptime of the system using /proc/uptime

-w (--warning)   = Min. number of uptime to generate warning
-c (--critical)  = Min. number of uptime to generate critical alert ( w < c )
-f (--for)       = Show uptime in a pretty format (Running for x weeks, x days, ...)
-s (--since)     = Show last boot in yyyy-mm-dd HH:MM:SS format (output from 'uptime -s')
-h (--help)
-V (--version)
-v (--verbose)   = debugging output

Note: -w and -c are required arguments.
      You can suffix both values with s for seconds (default), m (minutes), h (hours), d (days) or w (weeks).

Range support: You may specify a range for both warning and critical thresholds.
               This works without additional Perl modules.
Example: ./check_uptime -w 10m:4w -c 1m:8w
         Results in a critical state when uptime is below 60 seconds or higher than 8 weeks,
         and in a warning state when uptime is below 10 minutes or above 4 weeks.
