Output Fields

Table 1 lists the output fields for the show services rpm probe-results command. Output fields are listed in the approximate order in which they appear.

Table 1: show services rpm probe-results Output Fields

Field Name

Field Description

Owner

Owner name. When you configure the probe owner statement at the [edit services rpm] hierarchy level, this field displays the configured owner name. When you configure BGP neighbor discovery through RPM, the output for this field is Rpm-Bgp-Owner.

Test

Name of a test representing a collection of probes. When you configure the test test-name statement at the [edit services rpm probe owner] hierarchy level, the field displays the configured test name. When you configure BGP neighbor discovery through RPM, the output for this field is Rpm-BGP-Test- n, where n is a cumulative number.

Target address

Destination address used for the probes.

Source address

Source address used for the probes.

Probe type

Protocol configured on the receiving probe server: http-get, http-metadata-get, icmp-ping, icmp-ping-timestamp, tcp-ping, udp-ping, or udp-ping-timestamp.

Test size

Number of probes within a test.

Routing Instance Name

(BGP neighbor discovery) Name of the configured (if any) routing instance, logical system name, or both, in which the probe is configured:

  • When a routing instance is defined within a logical system, the logical system name is followed by the routing instance name. A slash ( / ) is used to separate the two entities. For example, if the routing instance called R1 is configured within the logical system called LS, the name in the output field is LS/R1.
  • When a routing instance is configured but the default logical system is used, the name in the output field is the name of the routing instance.
  • When a logical system is configured but the default routing instance is used, the name in the output field is the name of the logical system followed by default. A slash (/) is used to separate the two entities. For example, LS/default.

Probe results

Raw measurement of a particular probe sample done by a remote host. This data is provided separately from the calculated results. The following information is contained in the raw measurement:

  • Response received—Timestamp when the probe result was determined.
  • Client and server hardware timestamps—If timestamps are configured, an entry appears at this point.
  • Rtt—Average ping round-trip time (RTT), in microseconds.
  • Egress jitter—Egress jitter, in microseconds.
  • Ingress jitter—Ingress jitter, in microseconds.
  • Round trip jitter—Round-trip jitter, in microseconds.
  • Egress interarrival jitter—Egress interarrival jitter, in microseconds.
  • Ingress interarrival jitter—Ingress interarrival jitter, in microseconds.
  • Round trip interarrival jitter—Round-trip interarrival jitter, in microseconds.

Results over current test

Probes are grouped into tests, and the statistics are calculated for each test. If a test contains 10 probes, the average, minimum, and maximum results are calculated from the results of those 10 probes. If the command is issued while the test is in progress, the statistics use information from the completed probes.

  • Probes sent—Number of probes sent within the current test.
  • Probes received—Number of probe responses received within the current test.
  • Loss percentage—Percentage of lost probes for the current test.
  • 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 type icmp-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.

Results over last test

Results for the most recently completed test. If the command is issued while the first test is in progress, this information is not displayed

  • Probes sent—Number of probes sent for the most recently completed test.
  • Probes received—Number of probe responses received for the most recently completed test.
  • Loss percentage—Percentage of lost probes for the most recently completed test.
  • Test completed—Time the most recent test was completed.
  • 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 type icmp-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 for the most recently completed test.
    • Maximum—Maximum RTT, ingress delay, or egress delay measured for the most recently completed test.
    • Average—Average RTT, ingress delay, or egress delay measured for the most recently completed test.
    • Peak to peak—Peak-to-peak difference, in microseconds.
    • Stddev—Standard deviation, in microseconds.
    • Sum—Statistical sum.

Results over all tests

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.
