Port Number

This field is the TCP protocol connection port. The default value is 80.

Response Time Threshold

This field allows you to set the warning and critical threshold conditions based on the response time. The response time is the time in milliseconds it takes SolarWinds SAM to determine that a component is not Down and to retrieve any statistical data. See setting Application Monitor Thresholds for more information.
