Icinga2 using check_nscp_api for DriveSize

Hello everyone,

im using the check_nscp_api to check the drivesize on my Servers. But if i want to set crit to 98% and warn to 95% i get an error.

My Command:

command = [PluginDir + “/check_nscp_api” ]

arguments = {
	"--password" = "[password]"
	"-H" = "$host.address$"
