-**Dr. Elephant** is a performance monitoring and tuning tool for Hadoop. He automatically gathers all the metrics, runs analysis on them presents them in a simple way for easy consumption. His goal is to improve developer productivity and increase cluster efficiency by making it easier to tune Hadoop jobs. He analyzes Hadoop/Spark jobs using a set of configurable, rule based heuristics that provide insights on how a job performed and uses the results to make suggestions on how to tune the job to make it perform more efficiently.

+**Dr. Elephant** is a performance monitoring and tuning tool for Hadoop and Spark. It automatically gathers all the metrics, runs analysis on them, and presents them in a simple way for easy consumption. Its goal is to improve developer productivity and increase cluster efficiency by making it easier to tune the jobs. It analyzes the Hadoop and Spark jobs using a set of pluggable, configurable, rule-based heuristics that provide insights on how a job performed, and then uses the results to make suggestions about how to tune the job to make it perform more efficiently.
