The ProxySG appliance automatically adds a health check object when you add forwarding hosts.

When you add or edit health check objects in Configuration > Health Checks > General, the use of parentheses and square brackets in a forwarding host's name prevents the console from displaying the health check. There is no error message.

Invalid characters

Character	Example	Result
Colon(:)	Port:8080	ProxySG appliance displays an error: % The health check name has an invalid character. The invalid characters are ' : " and space.
double quotation	port"8080"	ProxySG appliance displays an error: % The health check name has an invalid character. The invalid characters are ' : " and space.
White space	port 8080	ProxySG appliance displays an error: % The health check name has an invalid character. The invalid characters are ' : " and space.
Square brackets([])	port[8080]	ProxySG appliance does not display an error and the health check does not appear in Configuration > Health Checks > General.
Parentheses()	port(8080)	ProxySG appliance does not display an error and the health check does not appear in Configuration > Health Checks > General.

Workaround

if you must use parentheses or square brackets in the health check name, view health checks from the command line interface (through the serial console or SSH) or go to https://ProxySG_IP:8082/health_check/view.
