I don't have a working example handy where I could do a screenshot, but on my system at work I just modified the [la] entry with extra lines like this:
AREA:la#00CC00:CPU Load Average
-u 1.0
--right-axis
1:0
--right-axis-label
Load
GPRINT:la:LAST: \: %5.1lf (cur)and that gives me markers and a label on the right axis of the cpu graphs.
What I meant by "set it up as a single line" was to make it look similar the -u & -l options:
--right-axis 1:0
--right-axis-label LoadThat will require some code additions, as noted in my earlier email.
This is working in SLES11, with rrdtool-1.3.7

** Hi Ralph,
I tried it on the la (default CPU) graph (in various positions) and it does not work for me on Xymon 4.3.7. My rrd version is old but it does support right-axis. Can you share the entire graphs.cfg entry you have working (or preferably using one of the default graphs)?
I'm not quite sure what you mean by 'To set it up as a single line in graphs.cfg'... There's more to it than adding an axis and a label?
Kind regards,

I just tried it on a random temperature graph, and it seems to work as two lines:
--right-axis 10:-1000That definitely put an axis on the right side of the graph.
To set it up as a single line in graphs.cfg, you'll need to do some work on xymon-4.3.7/web/showgraph.c. Starting at line 1068, you can see how other options work, such as --title, height, width, upperlimit & lowerlimit. I think you'd need to add something to the gdef_t struct and some handling in load_gdefs at line 314. Dunno what else.
But that's just a wild guess... :-)

Hi,
Has anyone got a right-axis working in Xymon graphs? The nearest info I can find is the post below, but I still can't get it to work seperating --right-axis from the parameter with a line-break. Does anyone have a working example? If I put --right-axis in the graphs.cfg, it just does not display it.
Many thanks,
SebA

Hang on a sec....
Debugging shows that there is a special case for -l and -u where it picks up two tokens on the same line (ie -l 0). The default case is that hobbitgraph.c expects parameters to be separated on word per line:
--right-axis 10:-1000
Or
-c
CANVAS:#449900
Hmmm that seems a bit counterintuitive as it is almost like rrdtool but not quite, which can be confusing.

I thought you could just add extra rrdtool graph commandline parameters to the hobbitgraph file for a graph section and hey presto it would use them. This seems to work for some and not for others. (eg -e and -A work)
It may be a more generic issue related to parameter assumptions within the code, but anyway, I added a some code to handle a couple of additional directives in hobbitgraph.cfg. (RSCALE, RFORMAT and RLABEL - in order to add a different scale to the right hand y axis.)
Should I look deeper into the code and see why --right-axis scale:shift, --right-axis-format and --right-axis-label seem to get ignored if I add them to hobbitgraph.cfg.
Or should I just use the code that I now have that uses my Hobbit specific directives.
Or am I missing something entirely altogether?
