statsd is a userspace daemon and integrated reporter that can be run on any number of Linux systems. Each system then Multicasts their stats so that any statsd running in listen mode can report the aggregate data.
[edit] Usage:
statsd --daemon : run as a background process and report statistics statsd --listen : listen and print a vmstat like output
