J-series™ Services Router Administration Guide

Table 77: Summary of Key RPM Output Fields (continued)

Field	Values	Additional Information
Minimum	Shortest round-trip time from the Services Router to
RTT	the remote server, as measured over the course of
	the test.
Maximum	Longest round-trip time from the Services Router to
RTT	the remote server, as measured over the course of
	the test.
Average	Average round-trip time from the Services Router to
RTT	the remote server, as measured over the course of
	the test.
Standard	Standard deviation of round-trip times from the
Deviation	Services Router to the remote server, as measured
RTT	over the course of the test.
Probes Sent	Total number of probes sent over the course of the
	test.
Loss	Percentage of probes sent for which a response was
Percentage	not received.

Round-Trip Time for a Probe

Samples Total number of probes used for the data set.

Earliest	System time when the first probe in the sample was
Sample	received.
Latest	System time when the last probe in the sample was
Sample	received.
Mean Value	Average round-trip time for the 50–probe sample.
Standard	Standard deviation of the round-trip times for the
Deviation	50–probe sample.
Lowest	Shortest round-trip time from the Services Router to
Value	the remote server, as measured over the 50–probe
	sample.
Time of	System time when the lowest value in the 50–probe
Lowest	sample was received.
Sample
Highest	Longest round-trip time from the Services Router to
Value	the remote server, as measured over the 50–probe
	sample.
Time of	System time when the highest value in the 50–probe
Highest	sample was received.
Sample

The Services Router maintains records of the most recent 50 probes for each configured test. These 50 probes are used to generate RPM statistics for a particular test.
