Integrate Spark Metrics using DSE Insights Metrics Collector

This article discusses the importance of metrics and visibility in distributed systems, specifically focusing on DSE Analytics. It highlights how DataStax Enterprise (DSE) Metrics Collector simplifies exporting metrics to monitoring solutions like Prometheus and Grafana. The integration of Spark Cassandra Connector monitoring is left for a second post. The article provides a bash script that sets up Prometheus & Grafana, hooks up spark metrics, and configures the DSE collectd directory with the necessary plugin. It also explains how to enable and configure the collectd-spark plugin and write_prometheus plugin. Finally, it demonstrates how to visualize the Spark data in both Prometheus and Grafana.
