There are 3 ping packets lost in the sample,whereas the loass shown is 9.5333 instead of 15% loss.
Can somebody tell why is this so. Actually i have to take out the data from the rrdfile at regular intervals and this is getting difficult for me to interpret what this value means.
Can somebody help.
