Monitoring Rpm Probes - Juniper J-Series Administration Manual

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
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.

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.

Additional Information
Click the Graph link to display the graph (if it is not
already displayed) or to update the graph for a particular
test.
If no source address is configured, the RPM probe
packets use the outgoing interface as the source address,
and the Source Address field is empty.
