Description

Instead of having multiple java vm to execute unix commands to collect system metrics (CPU utilization, network, memory, disk), it's more efficient to collect the metrics through JNI interface. SIGAR is a good replacement for Chukwa's input tools. All licenses considered, it's the next best option than reinvent the wheel.
