Hi Thanks for the info But still I have a doubt. In case of 3 PDP and 6 PDP per CDP what will be the value stored as. Lets say the ds values are 100, 200, 300, 400,500,600 So incase of 3 PDPD it will store the 300 the max of the 3 PDP right and 600 incase of 6 PDP. What I want to know is , is there a way where I can save the sum of the 3 PDP and 6 PDP OR the way I can display on the graph.

You want to know how much data has traveled in 8 hour, or in one day? bytes = (bytes/second)*seconds, provided that seconds != 0. You need a rate. Use AVERAGE. This rate is (bytes/second). Now you need to know the amount of seconds. Easy, you are specifying that in your graph command. Since you know the right hand side of the formula, you know the outcome. rrdtool graph .... --start end-8h ... CDEF:total=rate,28800,* ... or rrdtool graph .... --start end-1d ... CDEF:total=rate,86400,* ... followed by ... GPRINT:total:AVERAGE:"Total is %10.2lf bytes" In both cases: make sure to set the end time on a whole multiple of your CDP time duration. "--end 1086733615" is wrong, "-e 1086739200" is OK. 1086739200 is an integer times 86400, 1086733615 is not. HTH Alex -- I ask you to respect any "Reply-To" and "Mail-Follow-Up" headers.
