Ganglia

This initialization action installs Ganglia, a scalable monitoring system.

Using this initialization action

⚠️ NOTICE: See best practices of using initialization actions in production.

  1. Use the gcloud command to create a new cluster with this initialization action.

    REGION=<region>
CLUSTER_NAME=<cluster_name>
gcloud dataproc clusters create ${CLUSTER_NAME} \
    --region ${REGION} \
    --initialization-actions gs://goog-dataproc-initialization-actions-${REGION}/ganglia/ganglia.sh

  2. Once the cluster has been created, Ganglia is served on port 80 on the master node at /ganglia. To connect to the Ganglia web interface, you will need to create an SSH tunnel and use a SOCKS 5 Proxy with your web browser as described in the dataproc web interfaces documentation. In the opened web browser, go to http://CLUSTER_NAME-m/ganglia on Standard/Single Node clusters, or http://CLUSTER_NAME-m-0/ganglia on High Availability clusters.
