quick examples of how to change many many wsp (graphite/whisper) files settings

mass-aggregation-change.sh

for f in $(find $1 -iname "*.wsp"); do 
    if [ -a $f ]; 
        then /opt/graphite/bin/whisper-set-aggregation-method.py $f max; 
    fi; 
done

mass-size-change.sh

for f in $(find $1 -iname "*.wsp"); do 
    if [ -a $f ]; 
        then /opt/graphite/bin/whisper-resize.py $f 10s:12h 60s:7d 10m:3y; 
    fi; 
done

@gargnisha1605 and anyone else doing this for storage space, you can check your retention size per metric here: https://m30m.github.io/whisper-calculator/
Don't forget that every counter has 2 metrics (count and rate), and every timer has about 10 or so.
