stacctl - Man Page

stacctl [Options...] {COMMAND} [Options...]

stacctl is a tool that can be used to communicate with the stacd(8) daemon to retrieve operational data.

The following commands are understood:

tron

Trace ON. Enable code tracing, which is to say that lots of debug information will be printed to the syslog (e.g. systemd-journal).

troff

Trace OFF. Disable code tracing.

status

Show runtime status information.

ls

Show the list of I/O controllers. This will list all the I/O controllers configured in stacd.conf(5) as well as those discovered by the stafd(8) daemon.

The following options are understood:

-h,  --help

Print the help text and exit.

--version

Print the version string and exit.

-d,  --detailed

Print additional details.

On success, 0 is returned; otherwise, a non-zero failure code is returned.

Example 1. List I/O controllers

$ stacctl ls --detailed
