Elastic Infrastructure 7.4.0 introduces notable enhancements to the Elastic Stack, particularly in observability and monitoring capabilities, with key features including a new Metricbeat StatsD module for collecting custom metrics, an AWS Metrics UI for monitoring AWS resources, and expanded support for Kubernetes environments through the addition of CronJob metrics. The release also enhances AWS CloudWatch statistics integration and introduces new metricsets for AWS Elastic Load Balancing and Elastic Block Store services. Improved visualizations in Metricbeat dashboards now simplify the monitoring of KPIs for various modules such as Aerospike, Ceph, Couchbase, CouchDB, PostgreSQL, and Prometheus. Additionally, the Metrics Explorer offers customizable chart styles and Y-Axis domain options, while the Oracle integration receives an update with a new performance metricset covering open cursors and cache data.
