Cluster Summarization script
----------------------------
Key: CHUKWA-575
URL: https://issues.apache.org/jira/browse/CHUKWA-575
Project: Chukwa
Issue Type: New Feature
Components: scripts
Environment: Java 6, Mac OS X 10.6
Reporter: Eric Yang
Assignee: Eric Yang
Fix For: 0.5.0
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
