Comment 3 for bug 303274

The only other documentation about the sysinfo tool is its help page:

$ landscape-sysinfo -h
Usage: landscape-sysinfo [options]

Options:
  --version show program's version number and exit
  -h, --help show this help message and exit
  -c FILE, --config=FILE
                        Use config from this file (any command line options
                        override settings from the file) (default:
                        '/etc/landscape/client.conf').
  -d PATH, --data-path=PATH
                        The directory to store data files in (default:
                        '/var/lib/landscape/client/').
  -q, --quiet Do not log to the standard output.
  -l FILE, --log-dir=FILE
                        The directory to write log files to (default:
                        '/var/log/landscape').
  --log-level=LOG_LEVEL
                        One of debug, info, warning, error or critical.
  --ignore-sigint Ignore interrupt signals.
  --ignore-sigusr1 Ignore SIGUSR1 signal to rotate logs.
  --sysinfo-plugins=PLUGIN_LIST
                        Comma-delimited list of sysinfo plugins to use.
                        Default is to use all plugins.
  --exclude-sysinfo-plugins=PLUGIN_LIST
                        Comma-delimited list of sysinfo plugins to NOT use.
                        This always take precedence over plugins to include.

Default plugins: Load, Disk, Memory, Temperature, Processes, LoggedInUsers,
LandscapeLink, Network

Many of those options are not really useful for an end user. The most important ones are about the plugins I suppose, specially because some people prefer to disable the LandscapeLink one.
