Hi there,

I’m trying collectd 5.5 about the CPU usage percentage.
It works when set ‘ValuesPercentage’ to true. I got the cpu percentage per cpu core successfully.

But I also want to aggregate the CPU usage percentage using following config:

<Plugin aggregation>
    #Host "unspecified"
    Plugin "cpu"
    #PluginInstance "unspecified"
    Type "cpu"
    #TypeInstance "unspecified"

    GroupBy "Host"
    GroupBy "TypeInstance"

    CalculateNum false
    CalculateSum false
    CalculateAverage true
    CalculateMinimum false
    CalculateMaximum false
    CalculateStddev false

Seems when I enable ‘ValuesPercentage', I can’t get the cpu-average any more.
So please help me out.
