> Chukwa record metrics from name node, data node, job tracker, task tracker,
> etc, but the raw metrics does not help determine all aspect of the cluster
> health. For now, we have the following metrics in HBase:
> * System
> * Disk
> * Memory
> * Network
> * HDFS
> * Name Node
> * Data Node
> * Map Reduce
> * Job Tracker
> * Task Tracker
> We can further analyze the data to provide a summary for the cluster as these
> categories:
> * System - Performance profile of how busy the nodes are in the cluster
> * HDFS - Capacity of the disk storage, and health of the data in the file
> system
> * MapReduce - Capacity of the processing pipeline, and health of the
> processing system
