stacctl - STorage Appliance Connector (STAC) utility program

       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.

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