[Xymon] SPLITNCV RRD graph legends

[SebA]

The only problem I have with my graph code below is that I can't alias the
variable names to display something more informative in the graph legend.
Is there a solution for this, or is this just a feature of SPLITNCV that one
has to live with?  I tried replacing the @variables@ with explicit values
(one set of the lines below for each NCV variable), but the graph would not
display...

Kind regards, 

SebA

 However, in this case, I have asked the developer to put some carriage
returns into his JSON HTML display, so that looks like it will solve it,
although the first rrd file is being created as _u instead of u.  That's not
too important.  It looks like the rrd files are getting the correct data
anyway now, so it is just the graphing to do.  The example I found didn't
work for me.  This did:
 
 DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE
 LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@
 GPRINT:p at RRDIDX@:LAST:@RRDPARAM@ \: %5.1lf%s (cur)
 GPRINT:p at RRDIDX@:MAX: \: %5.1lf%s (max)
 GPRINT:p at RRDIDX@:MIN: \: %5.1lf%s (min)
 GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf%s (avg)\n

I had to replace @RRDMETA@ with @RRDPARAM@ based on an old post.

Kind regards,

I was hoping that Xymon's NCV parsing would understand JSON as the tutorial
@ http://www.xymon.com/xymon/help/howtograph.html does not specify that the
NCVs need to be on seperate lines (although I subsequently found that "man
xymond_rrd" does).  It's a shame because a lot of data is presented as JSON
these days.  For example, I have this test, which returns this:

http://URLremoved/ - Testing URL <http://192.168.4.135:8080/tracker/co.do>
yields:

{ u:1391595, rc:3517, asc:1628, usc:2154}
I am using SPLITNCV and it just creates a testname,_u.rrd file.
 
I doubt it would involve a huge diff to get /xymond/rrd/do_ncv.c to
understand this format.  I also doubt that it is currently within my level
of C programming proficiency though unfortunately.

Kind regards,
