RRDTool

RRDTool (Round Robin Database Tool) is a software system designed to efficiently store and display time-series data, such as network traffic or system metrics. It keeps a fixed amount of recent data by overwriting old data in a circular manner, ensuring consistent disk space usage. RRDTool provides tools for creating visual graphs and retrieving historical data, making it useful for monitoring and analyzing performance trends over time. Its design emphasizes automation and efficient data management, making it a popular choice for network and system administrators to track metrics without growing storage requirements indefinitely.
