Link Quality

Operations Monitor has the ability to ping the public IP of a subscriber or ping the IP of a proxy. You can access Link Quality under the Customer Experience & Troubleshooting section of the main menu. It sends out 10 ICMP Echo Request packets every minute with a 500 milliseconds delay between successive packets to an individual target. Based on the incoming responses and elapsed time for the requests, it reports on the target's reachability, packet loss and round trip delay.

For every pinged address, Operations Monitor measures an average value of round-trip time (RTT) and loss rate. The loss rate is the percentage of ICMP Echo Replies lost for a remote target as shown.
