[xymon]problems setting to 'derive'
Hello,
I'm using 2 test using same data to compare the difference between gauge & derive (derive is the best choice, because data that is continuously increasing in value between 00:00 and 23:59
When graph using Gauge, values are correct : field03a: 5 field03b: 17 field03c: 14 field04a: 3 field04b: 12 field04c: 15 Total: 66
=> same values in graph
But when i switch to derive, values in graphs look like field03a: 6m field03b: 4m field03c: 5.8m field04a: 4m field04b: 2m field04c: 2m Total: 0
Maybe i'm understing correctly 'derive' or there another things goes wrong ?

Someone have an idea ?

See http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html. There you'll see that there is quite a difference between gauge and derive. The type of measurement and what you want to know determine which data type is appropriate. If you are interested in the number of serious errors reported per second, derive is an appropriate type. Set a minimum value of zero, to prevent negative spikes in the graphs.

Hi, Thanks for your answer.
Minimum value already set (-l 0 on my first post) My max data value is about 400 (very lower than limit of a integer)
