[Monitorix-general] MySQL statistics show value: -nan

[czezz <cz...@o2...>]

Hi,
I have a problem with configuring monitorix to monitor MySQL.
My MySQL is installed locally on this same machine as monitorix.
I have created user with passwd as stated in manual but I still cannot get any values on graphs.
All statistics for MySQL are like: -nan
This is my part of configuration for MySQL:
# MYSQL graph
# -----------------------------------------------------------------------------
<mysql>
        conn_type = host
        list = localhost
        <desc>
                localhost = 3306, monitorixuser, passwdmonitorix
        </desc>
        rigid = 0, 2, 0, 0, 0, 0
        limit = 100, 100, 100, 100, 100, 100
</mysql>
Can anyone advise what Im doing wrong ?
Cheers,
Czezz
