How to use
|
|
----------
|
|
|
|
After installing the package you simply need to start the tuned
|
|
service either with system-config-services or from the
|
|
commandline in a rootshell via:
|
|
|
|
service tuned start
|
|
|
|
You can also automatically start it during system startup by
|
|
switching it on via chkconfig:
|
|
|
|
chkconfig tuned on
|
|
|
|
After that the daemon will run automatically and monitor the
|
|
usage of various system components. Based on that information
|
|
components will then be put into lower or higher power saving
|
|
modes to adapt to the current usage. Currently only ethernet
|
|
network and and ATA harddisk devices are implemented.
|
|
|
|
The config file /etc/tuned.conf contains several sections in
|
|
INI style. There is always a "main" section which controls
|
|
overall options of the daemon. Currently only 1 option
|
|
is available:
|
|
|
|
interval: Interval for monitoring and tuning in seconds.
|
|
Default is 10.
|
|
|
|
Each monitoring and tuning plugin has an own section then.
|
|
Currently only 1 option for plugins is available:
|
|
|
|
enabled: Enabled or disable the plugin. Default is True.
|
|
Any other value disables it.
|
|
|
|
WARNING: At the moment there is a small incompatibility with
|
|
tuned and NetworkManager which will results in connectivity
|
|
loss if you are using tuned and your network devices are
|
|
controlled by NetworkManager. This will be fixed in a future
|
|
version of tuned and NetworkManager. At the moment there
|
|
are two workarounds:
|
|
|
|
1) Don't use NetworkManager for your Ethernet devices but
|
|
configure them with system-config-network and enable the
|
|
network service.
|
|
2) Disabled the network tuning in tuned by editing
|
|
/etc/tuned.conf and uncomment the
|
|
# enabled=False
|
|
line in the NetTuning section.
