Description: Application Metrics provide information about the performance and resource usage of applications running on YARN. These metrics are essential for monitoring and optimizing applications in a distributed processing environment. They include data on CPU usage, memory, execution time, and other critical resources, allowing administrators and developers to identify bottlenecks, optimize performance, and ensure that resources are used efficiently. Metrics are collected in real-time and can be visualized through monitoring tools, facilitating informed decision-making regarding resource management and capacity planning. Additionally, application metrics are fundamental for trend analysis over time, enabling organizations to adjust their deployment and scalability strategies. In summary, these metrics are an integral part of the YARN ecosystem, providing visibility and control over application performance in a distributed computing environment.
