How to monitor HDFS performance without root privilege

Hi every one,
I have access to a cluster with a bunch of workstations. And I can install
and run HDFS smoothly without the root privilege. I wonder if there is a way
to monitor HDFS performance (e.g. read/write throughput) without using any
performance monitoring tool (e.g. nmon, tcpdump, ...) that requires root
privilege. Any suggestion is appreciated.

Thanks,
Thanh

You can use ganglia, without root priviliges as well as iostat for low level
disk io monitoring.
