Compressed memory is the amount of compressed memory in RAM.įree memory is memory not being used. Active memory is memory that has recentlyīeen used or is in use by applications. Memory that is in active use and cannot be cached to disk. When your computer started, how long it has been asleep and awake.ĭisplays the memory usage of the system in a traditionally pie-chart. Uptime is the time your computer has been working and available. With CPU usage aggregated into the parent process. With the Helper, the list shows top-5 of all processes on the system, including background processes, CPU usage per App is presented normalized across all CPU cores (0-100%).

OpenĪctivity Monitor by clicking its icon. Click an App in the list to switch to that App. Top-5 List of Applications using most CPU. Rotation correlates with the physical fans RPM. You can also see the current CPU and GPU temperature.įans are visible if the Helper is installed. The GPU model changesĭepending on, if the system uses the integrated or the discrete GPU. Normal, fair (fans running), serious and critical. The Thermal gauge represents the overall thermal state of the system. System reports the number of processes and threads running on the system. System load during the last one-, five-, and fifteen-minute periods. Load Average represents the average system load over a period of time. The Load is a measure of the amount of computational work that a computer system performs. The amount of time the CPU was busy executing code in kernel space and idle Is the amount of time the CPU was busy executing code in user space, sys CPU Usage is reported for the entire system.
