This capability allows the agent to provide comprehensive and near real-time insights into the performance and health of a system. By monitoring this many metrics, users can gain a detailed understanding of various aspects such as CPU usage, memory consumption, disk I/O, and network activity, which are critical for effective system monitoring and troubleshooting.
