Too many disks = no graph

This seems to be an issue with JFreeChart - there is no option to truncate the legend. The only solution I have found it to make the chart bigger. Obviously this is limited to your resolution in the GUI. You can set the size in a custom report but I am not sure you could make it big enough to show hundreds of disks.

A custom report may be the best option. With that you could just select the disks you want via multiple <field> elements.

Thanks for the reply Hunter.

Perhaps you could reduce the amount of disks per single report and split them into separate reports, like diskbusy1, diskbusy2 etc..

It may be possible to do this but it would require a lot more preprocessing since the charting engine doesn't have generic 'splitting' kind of filter on it. I would have to do it manually (ie one chart xml for disks 0-24, one for disks 25-50, etc). Not sure if that helps or not.

It may be easier to use the disk grouping feature of NMON and filter out the data at collection time.
