The blog post discusses the integration of Elasticsearch with Prometheus metrics, promoting the adoption of open standards such as OpenMetrics to enhance observability. It emphasizes the importance of open standards for interoperability, vendor neutrality, and maximizing user choice. Prometheus, recognized as a de-facto standard in cloud-native metric monitoring, offers an exposition format that facilitates the collection and visualization of metrics. The blog details how Elasticsearch can ingest Prometheus metrics, combining them with logs and APM data for comprehensive monitoring and analysis using Kibana. It also provides examples of deploying Metricbeat within a Kubernetes environment to scrape Prometheus metrics, demonstrating how to visualize these metrics within the Elastic Stack. The post underscores the value of integrating logs, metrics, and traces to build an observable system capable of identifying and diagnosing production issues effectively.
