Hi Henrik

Thanks This helped me a lot. I got the graph working, but it's very busy. I need to split this over 2, or even 3 graphs. However, before I bug you any more, I would love to RTFM, as you say.

I'd advise anyone trying to do custom graphs to read the "rrdcreate" man-page from RRDtool. Here you'll find this:

However, I found this. :-(

If you get the time, could you repair it?

Cheers, and thanks Vernon

I'd advise anyone trying to do custom graphs to read the "rrdcreate" man-page from RRDtool. Here you'll find this:

A ds-name must be 1 to 19 characters long in the

[no graphs show up]

My hobbitgraph.cfg entry for this looks like this.

---snip--- [ora9-sga] FNPATTERN tablespace(.*).rrd TITLE TableSpace Utilization YAXIS % Full DEF:p at RRDIDX@=@RRDFN@:pct:AVERAGE

The DEF: line here is wrong. The "pct" here is the name of the dataset you want to graph - the same string that you use in the "DS:" definition of the RRD file. So to get a graph of the siebprod_XDB data, you should have DEF:p at RRDIDX@=@RRDFN@:siebprod_XDB:AVERAGE LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@

If you want to graph more than one dataset in a single image, you just add more DEF and LINE entries - but make sure you keep a unique name for each of the DEF's you define. E.g.

      DEF:whsidx at RRDIDX@=@RRDFN@:siebprod_WHS_INDEX:AVERAGE
      DEF:whsdata at RRDIDX@=@RRDFN@:siebprod_WHS_DATA:AVERAGE
      LINE2:whsidx at RRDIDX@#@COLOR@:@RRDPARAM@
      LINE2:whsdata at RRDIDX@#@COLOR@:@RRDPARAM@

But that is usually not a good idea when you are also combining multiple RRD files into one graph.

Regards, Henrik
