Definition: The word 'runlevel_info' is a command-line utility used to monitor the running levels of various processes in Linux, macOS, Windows, or other systems. It's primarily useful for managing system resources like CPU usage, memory allocation, disk I/O, and network traffic. Here's a brief definition: - `runlevel_info`: A command-line tool designed to display information on the CPU, process, disk I/O, and network usage of various processes in Linux, macOS, Windows, or any other system. It uses the term 'runlevel' for these metrics, where 'runlevel' is typically a number representing a specific level of execution (e.g., 0 = background, 1-3 = foreground). - `CPU_usage`: This metric reports the CPU usage by process, indicating the percentage of CPU time each process has used. For example: ``` cpu_usage: - Running processes: 75% - Background processes: 25% ``` - `process_mem_usage`: Tracks memory utilization, measuring in bytes (KB, MB, GB) for running and background processes. - `disk_io_stats`: This displays disk I/O statistics by process. It includes disk usage per minute, percentage of used space, average read/write speeds, and time taken to complete I/O operations. - `network_traffic`: Measures network traffic including IP packets sent/received, latency, bytes transferred, and packet loss. Understanding and using these metrics in a system can help you manage resources effectively and monitor your systems' performance.
