Monitoring RPM Probes
The RPM information includes the round-trip time, jitter, and standard deviation
values for each configured RPM test on the Services Router. To view these RPM
properties, select Monitor>RPM in the J-Web interface, or enter the following CLI
show command:
show services rpm probe-results
In addition to the RPM statistics for each RPM test, the J-Web interface displays the
round-trip times and cumulative jitter graphically. Figure 11 on page 145 shows sample
graphs for an RPM test.

"\\teamsite1\default\main\TechPubsWorkInProgress\STAGING\images\".
In Figure 11 on page 145, the round-trip time and jitter values are plotted as a function
of the system time. Large spikes in round-trip time or jitter indicate a slower outbound
(egress) or inbound (ingress) time for the probe sent at that particular time.
Table 77 on page 145 summarizes key output fields in RPM displays.
