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.\n\n## Documentation\n\nFor more information on Dr. Elephant, check the wiki pages [here](https://github.com/linkedin/dr-elephant/wiki).\n\nFor quick setup instructions: [Click here](https://github.com/linkedin/dr-elephant/wiki/Quick-Setup-Instructions-(Must-Read))\n\nDeveloper guide: [Click here](https://github.com/linkedin/dr-elephant/wiki/Developer-Guide)\n\nAdministrator guide: [Click here](https://github.com/linkedin/dr-elephant/wiki/Administrator-Guide)\n\nUser guide: [Click here](https://github.com/linkedin/dr-elephant/wiki/User-Guide)\n\nEngineering Blog: [Click here](https://engineering.linkedin.com/blog/2016/04/dr-elephant-open-source-self-serve-performance-tuning-hadoop-spark)\n\n## Mailing-list \u0026 Github Issues\n\n~~Google groups mailing list: [Click here](https://groups.google.com/forum/#!forum/dr-elephant-users)~~ (Reached upper limit! please create github issues)\n\nGithub issues: [click here](https://github.com/linkedin/dr-elephant/issues)\n\n## Meetings\n\nWe have scheduled a weekly Dr. Elephant meeting for the interested developers and users to discuss future plans for Dr. Elephant.
