Prometheus has become a popular tool for monitoring and alerting in container systems, primarily due to its open-source nature and community support, but it faces challenges in large-scale deployments and cross-team collaboration, particularly with long-term data retention and high cardinality dimensions. While Prometheus excels in efficient server-side metric storage, its local storage model limits scalability and availability, necessitating complementary long-term storage solutions. Elastic Stack offers a way to enhance Prometheus's capabilities by providing centralized, scalable storage and allowing integration of various operational data types, such as logs and traces, for improved observability. With features like data rollups and advanced security measures, Elasticsearch enables long-term retention and secure access to operational data, overcoming some limitations of Prometheus's approach. Elastic Stack's capability to manage high cardinality dimensions without compromising storage efficiency and its support for streaming metrics via Metricbeat provide a more holistic approach to system observability. By integrating these tools, organizations can break down operational silos, gaining a comprehensive and secure view of their data across distributed environments.
