severity 717287 normal
# >3.10 will be the default kernel, so this plugin will break completly

Hi,

/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state is gone in kernels 
>=3.10, what can the cpuspeed plugin use instead?


cheers,
        Holger

For reference, this is the plugin code:

    for c in /sys/devices/system/cpu/cpu[0-9]*; do
        N=${c##*/cpu}

        echo "cpu$N.label CPU $N"
        echo "cpu$N.type DERIVE"

        if [ -r $c/cpufreq/cpuinfo_max_freq ]; then

            MAXHZ=$(cat $c/cpufreq/cpuinfo_max_freq)
            # Adding 10% to $MAXHZ, to cope with polling jitters
            # See bug D#615957
            MAXHZ=$(( $MAXHZ + $MAXHZ / 10 ))
            echo "cpu$N.max $MAXHZ"

            if [ "$scaleto100" = "yes" ]; then
                echo "cpu$N.cdef cpu$N,1000,*,$MAXHZ,/"
            else
                echo "cpu$N.cdef cpu$N,1000,*"
            fi
        fi

        if [ -r $c/cpufreq/cpuinfo_min_freq ]; then
            MINHZ=$(cat $c/cpufreq/cpuinfo_min_freq)
            echo "cpu$N.min $MINHZ"
        fi

        print_warning "cpu$N"
        print_critical "cpu$N"

    done
