Hi, everyone, I am learning RRDtool, I can't find any documents that describe what would happen when multiple sampling points were inserted in a single step.
Here's my test: rrdtool create mydata6.rrd --start 1396419600 --step 4 DS:mem:GAUGE:2000:0:4000000 RRA:AVERAGE:0.5:1:50 rrdtool updatev mydata6.rrd 1396419601:8 1396419604:14 I got the output: return_value = 0 [1396419604]RRA[AVERAGE][1]DS[mem] = 1.2500000000e+001 In the example above, the step is 4 seconds, I insert two sampling points whose value are 8 and 14 respectively, why I got the CDP value 12.5? What's the internal logic? Are there any documents describing the computing logic of rrdtool in more detail? -- View this message in context: http://rrd-mailinglists.937164.n2.nabble.com/RRDtool-computing-logic-help-tp7581888.html Sent from the RRDtool Users Mailinglist mailing list archive at Nabble.com. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
