RPM: ICMP ping probe (IPv4)

You can use real-time performance monitoring (RPM) to monitor network performance in real time and to assess and analyze network efficiency. Typically, you assess network performance in real time based on the jitter, delay, and packet loss experienced on the network. RPM is a service that enables a router to measure metrics such as round-trip delays and unanswered echo requests. To compute these parameters, RPM exchanges a set of probes with other IP hosts in the network for monitoring and network tracking purposes. These probes are sent from a source node to other destination devices in the network that require tracking. You can collect data such as transit delay and jitter from these probes and use the data to provide an approximation of the delay and jitter experienced by live traffic in the network. Different live traffic metrics, such as round-trip time (RTT), positive egress jitter, negative egress jitter, positive ingress jitter, negative ingress jitter, positive round-trip jitter, and negative round-trip jitter, can be obtained from the results of the RPM test. RPM calculates minimum, maximum, average, peak-to-peak, standard deviation, and sum calculations for each of these measurements. You can also use RPM probes to verify the path between BGP neighbors.
