-----------------------------------------------------------------

I've worked quite a bit with Sigar and it's java bindings. Is this issue still relevant? I
could take over and expose relevant cpu/disk/memory metrics. 

Most likely for CPU it'd be usual useer/sys/nice/idle/wait/irq/steals, same metrics per cpu
core.
For memory total/used/free/actual used and free. And for network active/passive opens, attempt
fails, in/out/retrans segs.
