Use these options to add options to the command specified. To add multiple options, specify -o|--opt multiple times (they will add together)
Options for different APIs:
all:
i Make all string comparisons case-insentitive
servicestatus|hoststatus:
c Show fields selected by -f as quoted CSV
C Same as C but also include the fields
X Same as C but use a more human-friendly set of names for the fields when printed
hostgroupmembers:
h Only show hosts (not the complete JSON data)
o Only show host_object_id (specifying both options will result in errors)
servicegroupmembers:
h Only show hosts (not the complete JSON data)
s Only show service names (not the complete JSON data)
o Only show service_object_id (specifying both options will result in errors)
