recommendation for system resource monitor.!!!

[sweetleaf]

seeking recommendation for a good system resource monitoring app that works well with window maker or blackbox.  I have looked through the ports and the ones i found say the port/s is broken. I would like one that shows cpu, ram , swap, file system ...such as / 90% /tmp 30% and network load.

I am running freebsd-5.1

Thanks in /advance
