show services monitoring twamp client probe-results

Syntax

Description

Display the results of the most recent Two-Way Active Measurement Protocol (TWAMP) probes. By default, all probe results are displayed, unless you specify the control-connection option when you issue the command. The control-connection option is required when you want to issue the command with one of the other options. For example, to see the probe results for a particular test session, you must also include the control-connection option to specify which connection contains the test session: show services monitoring twamp client probe-results control-connection control-connection-name test-session test-session-name.

Options

control-connection control-connection-name

(Optional, but required if specifying one of other options as well) Display probe results for the specified control connection between a TWAMP client and a TWAMP server.

source-address address

(Optional) Display results only for those probes with the specified IPv4 source address associated with a particular control connection.

status (FAIL | PASS)

(Optional) Display results only for those probes with the specified status associated with a particular control connection.

  • Values: Specify one of the following:

    • FAIL—Display results for failed probes.

    • PASS—Display results for passed probes.

target address

(Optional) Display results only for those probes with the specified IPv4 target address associated with a particular control connection.

test-session test-session-name

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

Output Fields

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

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

Field Name

Field Description

Level of Output

Owner

Owner name. Entries are listed in alphabetical order by owner name and then by test name. When you configure the control-connection statement at the [edit services monitoring twamp client] hierarchy level, this field displays the configured control-connection name.

All levels

Test

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

All levels

Target address

Destination address used for the probes. This field is displayed when the probes are sent to the configured targets.

All levels

Source address

Source address used for the probes.

All levels

Probe type

Protocol configured on the receiving probe server: twamp

All levels

Test size

Number of probes within a test.

All levels

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:

  • Probe response received

    • Probe sent time—Timestamp when the probe’s results were sent.

    • Probe rcvd time—Timestamp when the probe’s results were received.

  • Client and server offload timestamping—If PFE timestamping is configured, an entry appears at this point.

  • Rtt—Average ping round-trip time (RTT), in microseconds.

  • Rtt jitter—Round-trip jitter, in microseconds.

  • Egress jitter—Egress jitter, in microseconds.

  • Ingress jitter—Ingress jitter, in microseconds.

All levels

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.

  • Egress loss inferred—Computed unidirectional loss towards server (available only when stateful-sequence is enabled on the server)

  • Loss percentage—Percentage of lost probes for the current test.

  • Measurement—Measurement type: round-trip time, round-trip jitter, egress delay, egress jitter, ingress delay, or ingress jitter.

    For each measurement type, the following individual calculated results are provided:

    • Samples—Number of probes.

    • Minimum—Minimum RTT measured over the course of the current test.

    • Maximum—Maximum RTT measured over the course of the current test.

    • Average—Average RTT measured over the course of the current test.

    • Stddev—Standard deviation, in microseconds.

All levels

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.

  • Egress loss inferred—Computed unidirectional loss towards server (available only when stateful-sequence is enabled on the server)

  • Loss percentage—Percentage of lost probes for the most recently completed test.

  • Measurement—Measurement type: round-trip time, round-trip jitter, egress delay, egress jitter, ingress delay, or ingress jitter.

    For each measurement type, the following individual calculated results are provided:

    • Samples—Number of probes.

    • Minimum—Minimum RTT measured for the most recently completed test.

    • Maximum—Maximum RTT measured for the most recently completed test.

    • Average—Average RTT measured for the most recently completed test.

    • Stddev—Standard deviation, in microseconds.

All levels

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.

  • Egress loss inferred—Computed unidirectional loss towards server (available only when stateful-sequence is enabled on the server)

  • Loss percentage—Percentage of lost probes in all tests.

  • Measurement—Measurement type: round-trip time, round-trip jitter, egress delay, egress jitter, ingress delay, or ingress jitter.

    For each measurement type, the following individual calculated results are provided:

    • Samples—Number of probes.

    • Minimum—Minimum RTT measured over the course of the current test.

    • Maximum—Maximum RTT measured over the course of the current test.

    • Average—Average RTT measured over the course of the current test.

    • Stddev—Standard deviation, in microseconds.
