Chukwa

Chukwa is an open source data collection system for managing large distributed systems. It is a Hadoop subproject devoted to large-scale log collection and analysis built on top of the Hadoop Distributed File System (HDFS) and Map/Reduce framework.

Chukwa aims to provide a flexible and powerful platform for distributed data collection and rapid data processing, that is capable of modification to use newer storage technologies (HDFS appends, HBase, etc) as they mature. In order to maintain this flexibility, Chukwa is structured as a pipeline of collection and processing stages, with clean and narrow interfaces between stages.

Chukwa has four primary components:

1. Agents that run on each machine and emit data.
2. Collectors that receive data from the agent and write it to stable storage.
3. MapReduce jobs for parsing and archiving the data.
4. HICC, the Hadoop Infrastructure Care Center; a web-portal style interface for displaying data. Data is fetched from a MySQL database, which in turn is populated by a mapreduce job that runs on the collected data, after Demux. It is the central dashboard for visualize and monitoring of metrics collected by Chukwa.

Features include:

• Hadoop Infrastructure Care Center:
• Individual user view management
• Basic Drag and Drop Web portal functions
  • Multiple views per user
  • Multiple tabs page per view
  • Multiple widgets per tab page
  • Drag and Drop relayout individual view
• Basic view permission system
• external widgets integration
  • data integration. Using HICC existing UI component to display chart, table and graph.
  • direct UI integration. Component can provide a URL and HICC will display the html page as a widget on the portal page
• Collection components of Chukwa -- adaptors, agents, and collectors
• Use the default
• Write your own parser
• Fexible and powerful toolkit for displaying, monitoring and analyzing results to make the best use of the collected data
• Uses the same configuration system as Hadoop
