Hi, at first I am sorry for some very stupid question, but I am a beginner of using rrdtool and have tried a lot (ca. 20 hours) without success.
I have already studied the rrdtool create man page http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html and some other documentation, but it do not work as I want. What do I need? I have a file where I can find my values (atm cells). This are already *DELTA* values in atm cells, so I know that COUNTER is the wrong DST. I want to build a graph in bits/s. Do I need DERIVE, GAUGE or ABSOLUTE for the DST. I know: 1 atm cell = 53 byte = 424 bit. So I sent to the rrd database (file) the value*424. But I always get a graph width very high values which could not be correct (I have this problem when I use DERIVE, GAUGE or ABSOLUTE). I know it is not correct because I can also check the throughput with mrtg from a other device. Could it be, that the rrd tool can not calculate from the value*424 bit (ca. 900s value) to bit/s? It is also important that I do not get always exact 15min (900s) values. e.g. I get 905, 890, ... values. But I have the exact time which I can sent to my rrd database (file). Is this a problem when I update the database not exact with 900s updates? thanks best regards, Christoph PS: I have used the following rrdcommands with a perl script: $rrdtool create $directory_file --start $unixtime_new --step $step_sec DS:input:ABSOLUTE:$step_sec:U:U DS:output:ABSOLUTE:$step_sec:U:URRA:AVERAGE:0.5:1:8640 and for update $rrdtool update $directory_file $unixtime:$value_in:$value_out -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!
