Note
The last release of Amazon EMR to include Ganglia was Amazon EMR 6.15.0. To monitor your cluster, releases higher than 6.15.0 include the Amazon CloudWatch agent.
The Ganglia open source project is a scalable, distributed system designed to monitor
clusters and grids while minimizing the impact on their performance. When you enable Ganglia
on your cluster, you can generate reports and view the performance of the cluster as a
whole, as well as inspect the performance of individual node instances. Ganglia is also
configured to ingest and visualize Hadoop and Spark metrics. For more information about the
Ganglia open-source project, go to http://ganglia.info/
When you view the Ganglia web UI in a browser, you see an overview of the cluster's performance, with graphs detailing the load, memory usage, CPU utilization, and network traffic of the cluster. Below the cluster statistics are graphs for each individual server in the cluster.
The following table lists the version of Ganglia included in the latest release of the Amazon EMR 6.x series, along with the components that Amazon EMR installs with Ganglia.
