Dr. Elephant is a self-serve performance monitoring and tuning tool for Apache Hadoop and Apache Spark jobs and workflows. It automatically collects job metrics, analyzes them with pluggable rule-based heuristics, and presents tuning suggestions through a web UI.
Use cases
- monitor hadoop and spark job performance
- find why my spark job is slow
- tune hadoop mapreduce job configuration
- analyze cluster job efficiency across workflows
- get tuning suggestions for big data jobs
- track job-level metrics over time
When to choose
- you run Hadoop or Spark clusters and want automated job performance analysis
- you need heuristic-based tuning suggestions without manual metric digging
- you want a self-hosted web dashboard for job and flow-level monitoring
When to avoid
- you use modern alternatives like Spark 3 event-log UIs, YARN services, or cloud-native job analyzers
- your stack has no Hadoop or Spark workloads
- you need actively developed tooling - the project sees only occasional maintenance releases
