Tuned - command ``/usr/sbin/tuned-adm list``
============================================
This parser reads the output of the ``/usr/sbin/tuned-adm list`` command and
reads it into a simple dictionary in the ``data`` property with two of three
keys:
* ``available`` - the list of available profiles
* ``active`` - the active profile name
* ``preset`` - the profile name that's preset to be used when tuned is active
The ``active`` key is available when ``tuned`` is running, because the active
profile is only listed when the daemon is active. If ``tuned`` is not
running, the tuned-adm command will list the profile that will be used when
the daemon is running, and this is given in the ``preset`` key.
Sample data::
Available profiles:
- balanced
- desktop
- latency-performance
- network-latency
- network-throughput
- powersave
- throughput-performance
- virtual-guest
- virtual-host
Current active profile: virtual-guest
Examples:
>>> result = shared[Tuned]
>>> 'active' in result.data
True
>>> result.data['active']
'virtual-guest'
>>> len(result.data['available'])
9
>>> 'balanced' in result.data['available']
True
