The round-trip time (RTT) is the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received. This time delay therefore consists of the propagation times between the two points of a signal.
1. Download rtt
2. Open a terminal in Administrator mode
3. Invoke rtt with the following command, using the correct IP address:
java -jar rtt.jar <ip_address>
Here is an example:
A shell script sensor can be easily created for this to continuously monitor response time. Once a sensor is created, alerts can also be setup for an increase in response time. (for example, alert if rtt from xyz exceeds 10 seconds for 5 minutes).
