If I were you, I'd convert the 'minutes' to a percentage, else it will not graph well against time. After all, this is so many minutes over what time interval? What happens when you get larger granularity graphs and the samples are averaged over larger intervals? The graphs could be very misleading. Multiply by 60 (to get seconds) and divide by the time interval in question then multiply by 100 to get a percentage utilisation...
By default, rrdtool will use a 'k' prefix when the value is over 1000, and similarly for other prefixes. So if your unit is '' (nothing) then at 1000 you will see 1k. If you don't want it to do this, then try out '--units-exponent 0 --alt-y-grid' which prevents this behaviour (using an exponent of 3 will make everything always display in k) Steve Shipway [email protected] -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of mmartin Sent: Wednesday, 23 April 2014 9:49 a.m. To: [email protected] Subject: Re: [rrd-users] The Y-Axis is Displaying an Incorrect Unit Hey Steve, thanks again for the reply, much appreciated... Ok, no problem. I've already modified my script to send bytes instead. I am also sending "CPU-Time" as part of the PerformanceData, which is currently sent in 'minutes'. With the unit of measure being "m". It used to be "min", but it didn't seem to recognize it so I changed it to just "m" because I read somewhere on oss.oetiker.ch that it recognizes *m*inutes, *s*econds... *w*eek, *d*ay, etc... But the Y-Axis is using the Unit "k". Is there any special option I need to use in order to use minutes as the unit of measure? Is this also a case where I should send the data in seconds, instead of minutes..?
