Description: Node health in Jenkins refers to the overall performance and stability of a node within a continuous integration and continuous delivery (CI/CD) environment. A node in Jenkins is a machine that runs jobs or tasks, and its health is crucial to ensure that build and deployment processes are carried out efficiently. Node health is assessed through various parameters, including system load, memory usage, connection status, and resource availability. A healthy node can run multiple jobs simultaneously without experiencing bottlenecks, allowing development teams to deliver software more quickly and reliably. Monitoring node health is essential to identify issues before they impact the overall system performance. Jenkins provides tools and plugins that allow administrators to monitor node health, facilitating the identification of inactive or overloaded nodes. Maintaining node health is fundamental to optimizing workflows in agile development environments, where speed and efficiency are paramount.
