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:
-
- Agents that run on each machine and emit data.
- Collectors that receive data from the agent and write it to stable storage.
- MapReduce jobs for parsing and archiving the data.
- 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.
