Table 498: show services rpm probe-results Output Fields (continued)
Field Description Field Name
Displays statistics made for all the probes, independently of the grouping into tests, as well as statistics
for the current test.
•
Probes sent
—Number of probes sent in all tests.
•
Probes received
—Number of probe responses received in all tests.
• Loss percentage —Percentage of lost probes in all tests.
•
Measurement —Measurement type. Possible values are round-trip time, positive round-trip jitter,
negative round-trip jitter, egress time, positive egress jitter, negative egress jitter, ingress time,
positive ingress jitter, negative ingress jitter, and, for the probe types
icmp-ping-timestamp and
udp-ping-timestamp
, the egress delay and ingress delay.
For each measurement type, the following individual calculated results are provided:
•
Samples
—Number of probes.
• Minimum —Minimum RTT, ingress delay, or egress delay measured over the course of the current
test.
•
Maximum
—Maximum RTT, ingress delay, or egress delay measured over the course of the current
test.
• Average —Average RTT, ingress delay, or egress delay measured over the course of the current
test.
•
Peak to peak
—Peak-to-peak difference, in microseconds.
• Stddev —Standard deviation, in microseconds.
•
Sum
—Statistical sum.
