Expected status code ranges. This setting allows you to specify multiple success code ranges in the format 200-299, 301-301. If these status codes are received as response from an endpoint when a health check is done, Traffic Manager marks those endpoints as healthy. You can specify a maximum of eight status code ranges. This setting is applicable only to HTTP and HTTPS protocol and to all endpoints. This setting is at the Traffic Manager profile level and by default the value 200 is defined as the success status code.

Probing interval. This value specifies how often an endpoint is checked for its health from a Traffic Manager probing agent. You can specify two values here: 30 seconds (normal probing) and 10 seconds (fast probing). If no values are provided, the profile sets to a default value of 30 seconds.
