Redis Session DB Shows Zero 0 Keys for sessions?

Question

When looking at the Redis Manager in the Back End, it always shows zero (o) keys for the sessions?

The .var/session is also empty. Any idea on this?

We are running CE1.9.2.2.

do you have these files ?

app/etc/modules/Cm_RedisSession.xml
app/code/community/Cm/RedisSession

is it enabled?

 app/etc/modules/Cm_RedisSession.xml

<config>
<modules>
<Cm_RedisSession>
<active>false</active>
<codePool>community</codePool>
</Cm_RedisSession>
</modules>
</config>

also use lzf for compression

Important: The Cm_RedisSession module in CE 1.8 is disabled by default. Magento disables the module to avoid unnecessary connection tries to Redis when you choose to use file, database, or a different session storage method.

To enable Magento to use Redis, perform the following tasks:

Enable the Cm_RedisSession module.
Open magento-install-dir/app/etc/modules/Cm_RedisSession.xml in a text editor.
Change the value of to true.
Save your changes to Cm_RedisSession.xml and exit the text editor.
Modify magento-install-dir/app/etc/local.xml.
For configuration information, see the sample provided with Magento in magento-install-dir/app/etc/local.xml.additional and also see the Readme (session) and Readme (back end).
Flush the Magento cache in any of the following ways:
If you have access to the file system as the owner of the files in the Magento installation directory, change to that directory and enter rm -rf var/cache.
Log in to the Admin Panel as an administrator.
Click System > Cache Management, then click Flush Magento Cache at the top of the page.
