Ambari Metrics System

The Ambari Metrics System is a tool used in big data environments, primarily with Apache Hadoop. It collects and stores performance data from various components of a Hadoop ecosystem, such as servers and applications. This data helps administrators monitor system health, optimize performance, and troubleshoot issues. By providing insights into metrics like resource usage and system workload, it enables better decision-making and ensures efficient operation of data processing tasks. Essentially, it acts as a health monitor for large data processing systems, helping users ensure everything is running smoothly.
