show services rpm twamp client probe-results

Syntax

Description

Display the results of the most recent real-time performance monitoring (RPM) Two-Way Active Measurement Protocol (TWAMP) probes sent from the TWAMP client to the TWAMP server. You can also view the results of the probes or test packets sent from a TWAMP client to a TWAMP server for a particular control-connection, or a test-session associated with a control-connection.

Options

none

Display all results of the most recent TWAMP probes.

control-connection control-connection-name

(Optional) Display information for the specified control-connection between a TWAMP client and a TWAMP server.

test-session test-session-name

(Optional) Display information for the specified test session associated with a control-connection between a TWAMP client and a TWAMP server.

Required Privilege Level

Output Fields

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

Table 1: show services twamp client probe-results Output Fields

Field Name

Field Description

Owner

Name of the session-sender or the control-client, which is the TWAMP client. When you configure the control-client-name option at the [edit services rpm twamp client control-connection control-connection-name] hierarchy level, this field displays the configured owner name or the client name.

Test

Name of a test representing a collection of probes. When you configure the test-session test-name statement at the [edit services rpm twamp client control-connection control-connection-name] hierarchy level, the field displays the configured test name.

server-address

Destination address used for the probes.

server-port

Destination port used for the probes.

Client address

Source or TWAMP client address used for the probes.

Client port

Source or TWAMP client port used for the probes.

TWAMP-Server-Status

Possible values:

  • Light: the control-type light statement is configured for the control connection.
  • Connected or Not Connected: for control connections configured with the control-type managed statement, displays whether or not the connection is up.

Number-of-Retries-with-TWAMP-Server

The number of times the system has tried to connect to the TWAMP server.

Reflector address

Session-reflector or TWAMP server address used for the probes.

Reflector port

Session-reflector or TWAMP server port used for the probes.

Sender address

Session-sender or TWAMP client address used for the probes.

Sender-port

Session-sender or TWAMP client port used for the probes.

Local-link

Egress logical interface for the link-local address

Routing Instance Name

Name configured on the routing-instance statement for the control connection.

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.

Destination Interface Name

Name of the interface configured on the TWAMP server or the session-reflector on which the TWAMP probe packets sent from the TWAMP client are received.

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.
