We have two ways to find the response time:
2. If the ICMP Ping fails, we will do a TCP\UDP Port check in the remote system. This is based on the mode of the monitoring you

connect to the port 23 and check whether the system is up. The time
taken for connnecting to the above port is taken as Response Time.
