Hi,
Someone had some feature requests for "fancier graphs". My standard
reply is "the stats the pool are collecting aren't as interesting as
you think" or sometimes "it's on the todo, but pretty far down".
I just thought of another way: You get the RRD files and figure out
what to do with them. So to that end I've added a link to the RRD
files next to the CSV link on the server stats page!
If you don't know about rrdtool, you can read more at http://
oss.oetiker.ch/rrdtool/
Please don't setup something to download the RRD file frequently
(more than say every few days). The RRD files have the same data as
the CSV data (less actually), but obviously it's already in RRD
format ready to be graphed with rrdtool.
FWIW, the graphs on the site are made with these parameters:
'--lazy',
'--end' => 'now',
'--start' => 'end-3d',
'--width' => 420,
'--height' => 130,
'--height' => 160,
'--title' => $title,
'--lower-limit' => -10,
'--upper-limit' => 20,
'--slope-mode',
qq[DEF:score=$rrd:score:AVERAGE],
qq[DEF:step=$rrd:step:AVERAGE],
q[CDEF:step_blue=step,1,LT,INF,0,IF],
q[CDEF:step_yellow=step,0.6,LT,INF,0,IF],
