I've gone through the tutorials & manuals, but could not find a thorough explanation or demo of the use of DERIVE. Here are the two DBs I created:
rrdtool create nsm1.rrd \ --start 1075810000 \ DS:events:COUNTER:600:U:U \ RRA:AVERAGE:0.5:1:105120 rrdtool create nsm2.rrd \ --start 1075856400 \ DS:eventd:DERIVE:600:U:U \ RRA:AVERAGE:0.5:1:105120 And I updated them in the following way (in a shell script): events=......(from input source) eventd=$events /usr/local/bin/rrdtool update nsm1.rrd "$mytime:$events" /usr/local/bin/rrdtool update nsm2.rrd "$mytime:$eventd" However, the 2 graphs look the same -- as a matter of fact, the 2 DBs are exactly the same! Why?? Hints will be much appreciated! -Bill -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
