Hi Stef,

if you find out how, we are interested in the solution.

At our side we would like to have the cpu-utilization in addition to the
load under the point cpu...

Best

Hi,

Me again ;)

How can I change the graphs that are displayed?  I want to put 2 graphs on th
e memory page (the normal memory usage and the swap-in/swap-out).  I know I can

change TEST2RRD to change the graph per page, but I can only specify 1 graph.
Same for cpu, I want to display the load and the "vmstat1" graphs.

I'm not a programmer, but as far as I can see, you can specify 1 graph for 1 page.  This should be change so you can specify multiple graphs.  There is a framework for multiple graps for disk, inode and qtree.
I think there are 2 changes needed:  One in the file that parses the variable TEST2RRD (lib/hobbitrrd.c) so you can specify multiple graphs / page.  And one in the file that generates the html pages (lib/htmllog.c).

Yes, but those are graphs of the same type (disk). What you're after are
combining graphs of different types (cpu, vmstat, memory). The way the
current graphs code is structured makes that difficult.

It's a bit more complex than that :-)

The lib/hobbitrrd.c file is right - you should look at the 
hobbit_graph_text() routine, which is the one that generates the
HTML links to the graph images. But it's currently pretty much tied
into generating one graph at a time.

Argh.

Ok, I think it's time to search for my C book from college ;)
