USAGE:
$scriptname [-drqV] [-i instances] [-n number] [-m module] [-h device]

EXAMPLE:
-h <device id> | <device hostname wildcard>  Poll single device
-h odd                                       Poll odd numbered devices  (same as -i 2 -n 0)
-h even                                      Poll even numbered devices (same as -i 2 -n 1)
-h all                                       Poll all devices
-h new                                       Poll all devices that have not had a discovery run before

-i <instances> -n <number>                   Poll as instance <number> of <instances>
                                             Instances start at 0. 0-3 for -n 4

OPTIONS:
 -h                                          Device hostname, id or key odd/even/all/new.
 -i                                          Poll instance.
 -n                                          Poll number.
 -s                                          Sends alerts even if they have already been sent.
 -q                                          Quiet output.
 -V                                          Show version and exit.

DEBUGGING OPTIONS:
 -r                                          Do not create or update RRDs
 -d                                          Enable debugging output.
 -dd                                         More verbose debugging output.
 -m                                          Specify module(s) (separated by commas) to be run.
