*OpenLMI Fan* usage
===================
Examples for common use cases listed below are written in `lmishell`_.
Set up
------
*OpenLMI Fan* provider uses `lm-sensors`_ to find, observe and manage installed
fans. In order to make the fans exposed to it, one operation needs to be done:
.. code-block:: sh
sensors-detect
``sensors-detect`` is a script shiped with ``lm_sensors`` package in *Fedora*
which tries to load correct modules for various sensor devices found in system.
It also writes a config used by ``sensors`` library which is utilised in this
provider. Please refer to its *sensors-detect (8)* man-page.
Examples
--------
Listing installed fans
~~~~~~~~~~~~~~~~~~~~~~
::
c = connect("host", "user", "pass")
for fan in c.root.cimv2.LMI_Fan.instances():
print(fan.ElementName)
.. seealso::
:ref:`LMI_Fan<LMI-Fan>`
Getting fan's speed
~~~~~~~~~~~~~~~~~~~
Current value can be read from :ref:`CurrentReading<CIM-NumericSensor-CurrentReading>`
property. It's measured in *revolutions per minute*.
::
c = connect("host", "user", "pass")
for fan in c.root.cimv2.LMI_FanSensor.instances():
print("%s:\t%s RPM" % (fan.Name, fan.CurrentReading))
.. seealso::
:ref:`LMI_FanSensor<LMI-FanSensor>`
