Hi all

I am sure this has been asked and answered, but I can't find it in the list s=
earch.

I have a single test pumping out a number of data metrics.
Imagine this output (fictional, but representative of my problem)
        Rusers=3D45
        Users=3D104
        Mqueue=3D32014
        Rqueue=3D0
        ReadPerSec=3D24035
        OtherData=3D2128

NCV plugs these values into an RRD file very nicely, but of course you plot t=
hem on the same graphs, it becomes meaningless because of the scale.
Users and Rusers looks like a flat line down in the weeds, and only Mqueue an=
d ReadPerSec have any real visibility.

How can I display 2, or even 3 graphs on the same page with this data.
One graph with Users and Rusers (Because they are in the similar scale range)
Another with Mqueue ad ReadPerSec and potentially Rqueue - again because of a=
 similar scale range.
And if possible, a third graph for OtherData

3 graphs with 3 scales using different fields from the same rrd file on the s=
ame page.
Possible?

Cheers
      V

P.S. To those who celebrate, a Merry Christmas to you all. To those who do no=
t, a safe and enjoyable holiday to you.

Xymon can not do this for you.
But you can do this yourself when you send the data from the client to the 
server.  Just add <img src=....> to your test and point it to the image you 
want.  You can wrap it in a <a href=...></a> so you click on it to open the 
4-pages graph.  The correct links can be copied from the address bar from 
your browser.

I'm not at work, so I can not copy an example, but I hope you understand the 
idea.

You don't have to plot all data from an RRD in the same graph. E.g. the
"vmstat.rrd" files collect tons of data (around 20, if memory serves me right=
),
but there are several different graph-definitions that use this rrd-file to
display only a few of them.

You can only do this on the "trends" page; if you have a custom status column,
those status pages will only know how to show a single graph.

On the "trends" status, say you have a "mydata1", "mydata2" and "mydata3"
graphs defined in the hobbit-graphs.cfg file. Then you can put a
   TRENDS=3D*,mydata;mydata1|mydata2|mydata3
on the host definitions in bb-hosts, and the trends page will show those
three graphs one after the other. Note: The "GRAPHS" setting in hobbitserver.=
cfg
must have "mydata" listed as the graph, not "mydata1" (or 2 or 3).

Henrik
