connection-latency-show

This command is used to display latency information for connections on the switch. Comparing latency information for connections at various times can show whether the network performance has changed or stayed the same, and potentially eliminate the network as the cause of the problem

Syntax   connection-latency-show

min high resolution time: #ns

Displays the minimum latency in nanoseconds.

max high resolution time: #ns

Displays the maximum latency in nanoseconds.

num-bins num-bins-number

Specify the number of bins to divide the latency range. Bins display the number of connections at each latency interval.

Formatting Options

format fields-to-display

Display output using a specific parameter. Use all to display all possible output.

parsable-delim character

Display output formatted for machine parsing using a specified delimiter.

sort-asc

Display output in ascending order.

sort-desc

Display output in descending order.

show dups

Display duplicate entries in the output.

layout vertical|horizontal

Format the output in a vertical or horizontal layout.

show-interval seconds-interval

Repeat the show command at a specified interval.

show-headers|
no-show-headers

Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.

count-output

Display the number of entries in the output. This is useful with vRouter show commands.

unscaled

Display full values in the output instead of scaled approximate values.

raw-int-values

Display integer values instead of mapped values

sum-by

Aggregate output by specific parameters. If sum-by fields are specified, records that have the same value in sum-by fields are combined and displayed as one aggregate record. NOTE: This option is only available for show commands that collect statistics such as connection-stats-show.

Defaults   None

Access   CLI

History   Command introduced in Version 2.0.

Usage   You can display all of the latency information about a connection or you can filter by the number of bins to display. Comparing latency information for connections at various times can show whether the network performance has changed or stayed the same, and potentially eliminate the network as the cause of the problem

Examples  To display all latency information on pleiades24, use the following command:

CLI network-admin@switch > connection-latency-show
