[rrd-users] since when rrdtool tune can add another DS?

2015-10-15 Thread Petr

Hi Peter, in the 1.5 series there is a much better solution for the whole 'modify rrd' problem ... create has the ability to pre-populate a new rrd file based on an existing one ... the stuff in rrd_tune is obviously a merge error, stuff being documented before it was ever implemented. cheers t

Hello, I have a 1-wire setup in my attic. I log temperature and humidity and generate daily/weekly/monthly graphs. I use a modified temps.pl from Thierry Hugue. What I would very much like is to graph the local maximum and minimum temperature. This would be roughly the maximum and minimum

Hi, I've been working on a logging application that uses rrdtool. It works brilliantly on my PC, not so good on the Raspberry Pi model B+. But before I go there, there's something interesting I noticed while working on the PC. I'm creating a database with the following command (in rrdpytho
