		-s Set to 1 for Secure HTTPS Connection
		-c Sets what you want to do
				status - get the status of the SAN
				disk - Get performance data of the disks
				controller - Get performance data of the controllers
				named-volume - Get the staus of an individual volume - MUST have -n volumename specified
				named-vdisk - Get the staus of an individual vdisk - MUST have -n volumename specified
				vdisk - Get performance data of the VDisks
				volume - Get performance data of the volumes
				vdisk-write-latency - Get vdisk write latency (only available in later firmwares)
				vdisk-read-latency - Get vdisk read latency (only available in later firmwares)
		-S specify the stats to get for performance data. ONLY works when -c is specified
		-u Units of measure. What should be appended to performance values. ONLY used when -c specified.
		-w Specify Warning value
		-C Specify Critical value
		-t Specify how critical warning is calculated (DEFAULT greaterthan)
				lessthan - if value is lessthan warning/critical return warning/critical
				greaterthan - if value is greaterthan warning/critical return warning/critical
		-n Volume Name to be used with -c named-volume or -c named-vdisk
	   
Examples
		Just get the status of the P2000
		./check_p2000_api.php -H 192.168.0.2 -U manage -P !manage
		Get the status of the volume name volume1 on the P2000
		./check_p2000_api.php -H 192.168.0.2 -U manage -P !manage -c named-volume -n volume1
 
		Get the CPU load of the controllers and append % to the output
		./check_p2000_api.php -H 192.168.0.2 -U manage -P !manage -s 1 -c controller -S cpu-load -u \"%\"
 
		Get the CPU load of the controllers and append % to the output warning if its over 30 or critical if its over 60
		./check_p2000_api.php -H 192.168.0.2 -U manage -P !manage -s 1 -c controller -S cpu-load -u \"%\" -w 30 -C 60
 
Setting option -c to anything other than status will output performance data for Nagios to process.
You can find certain stat options to use by logging into SAN Manager through the web interface and
manually running the commands in the API. Some options are iops, bytes-per-second-numeric, cpu-load,
write-cache-percent and others. If using Warning/Critical options specify a stat without any Units
otherwise false states will be returned. You can specify units yourself using -u option.
