Hello,
rrdtool.exe create latency.rrd
--start now
DS:response:GAUGE:600:U:U
RRA:MIN:0.5:12:8760
RRA:MAX:0.5:12:8760
RRA:AVERAGE:0.5:12:8760
"ERROR: latency.rrd: found extra data on update argument: 0.40:0.88:0.73"
rrdtool update latency.rrd 08/10/2015_11:33:0.40:0.88:0.73
0.40 = Minimum
0.88 = Maximum
0.73 = Average
Is it the decimal point its having issues with?

Itâs the colons in your time. Send epoch, or âNâ for now, and remove the date/time stamp.

That's because you are offering 3 values to an RRD that's configured to take only one.

rrdtool update latency.rrd 08/10/2015_11:33:0.40:0.88:0.73
0.40 = Minimum
0.88 = Maximum
0.73 = Average

It doesn't work like that. If you want to record the min/avg/max values from a ping then you need to define THREE DSs, eg response_min, response_avg, response_max
You can then define your RRAs as required. You cannot be selective about this, so you will end up with all 9 permutations of min of min, min of avg, min of max, avg of min, ... Only three of these (min of min, avg of avg, max of max) are actually useful.

Hi,

I believe you have to use -c CANVAS#000000, or --color CANVAS#000000.
Same goes for the other color definitions too.

Solved.
For future ref the correct way is

"--color=CANVAS#000000",

Hi Petteri,

there are several valid ways to write this ...

"-c","CANVAS#000000"

"--color","CANVAS#000000"

"--color=CANVAS#000000"

this is not rrdtool specific, but they way argument parsing on unix
works in general ...

cheers
