Hadoop Kelvin

Hadoop Kelvin is a network monitoring system designed for the Hadoop Map-Reduce framework. It monitors data (not control) traffic between Hadoop nodes and provides the basis for multiple ways to store and access the stored monitoring data (the current implementation provides for log-based storage). It is designed to be easily extensible, flexible and to operate with a minimal effect on the running time of Hadoop jobs.
