The command "atop -m" is used to activate the memory view in atop, a Linux task resource monitor.
When you run "atop -m," it will display various memory-related information such as memory usage, utilization, and statistics for individual processes and memory regions. This information can help you understand how memory is being utilized by different processes on your system.
Here's an overview of the memory-related information you can expect to see using this command:
-
Process-specific memory usage: This section shows memory usage for each running process, including the amount of physical and virtual memory used, resident set size (RSS), and shared memory usage.
-
Global memory usage: This section provides an overview of memory utilization on the system, including the total amount of memory, free memory, used memory, and memory utilization percentage.
-
Memory statistics: This section displays memory statistical data, including the number of pages allocated, faults, pageins, pageouts, and various other memory-related events.
By running "atop -m," you can get a real-time snapshot of memory consumption and identify any processes or memory regions that might be causing high memory usage.
