skywalkctl - Interact with Skywalk subsystem
SYNOPSIS
skywalkctl [ -f OUTFILE ] <command> [ <args> ]
DESCRIPTION
skywalkctl is a utility used to interact with the Skywalk subsystem, which provides the plumbing between various networking-related pieces
of software and hardware. It should only be used in a test and debug context. Using it for any other purpose is strongly discouraged.
OPTIONS -f OUTFILE
Redirect output to the file specified by OUTFILE, instead of stdout.
COMMANDS
tree [ ROOT-UUID ]
Output JSON representing a tree of all current Skywalk objects. If provided, the tree will start at ROOT-UUID instead of the global
root.
channel-stats [ --interval, -I interval ]
Display performance and error statistics for all currently registered Skywalk channels.
-I interval
Re-print channel statistics with a period of interval seconds, until the SIGINT signal is received.
list-providers [ --details, -D ]
Print a human-readable table of Skywalk nexus providers and their child instances
-D Provide more details about each provider
netns [ -a ] | [ -i, --ip IP -p, --proto PROTO ]
Print information about L4 port reservations for the given <IP, PROTO> where IP is either an IPv4/v6 address or 'global', and PROTO
is the common name for a transportation-layer protocol ('tcp' or 'udp').
-a ignore any other specifiers and list the contents of every namespace, one after another

ctlstat -- CAM Target Layer statistics utility
SYNOPSIS
ctlstat [-t] [-c count] [-C] [-d] [-D] [-j] [-l lun] [-n numdevs] [-w wait]
DESCRIPTION
The ctlstat utility provides statistics information for the CAM Target Layer. The first display (except for dump and JSON modes) shows aver-
age statistics since system startup. Subsequent displays show average statistics during the measurement interval.
The options are as follows:
-t Total mode. This displays separate columns with the total CTL read and write output, and a combined total column that also
includes non I/O operations.
-c count Display statistics this many times.
-C Disable display of CPU statistics.
-d Display DMA operation time (latency) instead of overall I/O time (latency).
-D Text dump mode. Dump all available statistics every 30 seconds in a text format suitable for parsing. No statistics are com-
puted in this mode, only raw numbers are displayed.
-h Suppress display of the header.
-j JSON dump mode. Dump all available statistics every 30 seconds in JavaScript Object Notation (JSON) format. No statistics are
computed in this mode, only raw numbers are displayed.
-l lun Request statistics for the specified LUN. This option is incompatible with total (-t) mode.
-n numdevs Display statistics for this many devices.
-w wait Wait this many seconds in between displays. If this option is not specified, ctlstat defaults to a 1 second interval.
EXAMPLES
ctlstat -t
Display total statistics for the system with a one second interval.
ctlstat -d -l 5 -C
Display average DMA time for LUN 5 and omit CPU utilization.
ctlstat -n 7 -w 10
Display statistics for the first 7 LUNs, and display average statistics every 10 seconds.

Hi
when I do dtrace -l | awk '{print $2}' I get a list of providers. Some of them are similar providers. I want to receive only once the same provide name.
