$ man top
CPU Percentage of processor usage, broken into user, system, and idle components. The time period for which
these percentages are calculated depends on the event counting mode.
Disks Number and total size of disk reads and writes.
LoadAvg Load average over 1, 5, and 15 minutes. The load average is the average number of jobs in the run
queue.
MemRegions Number and total size of memory regions, and total size of memory regions broken into private (broken
into non-library and library) and shared components.
Networks Number and total size of input and output network packets.
PhysMem Physical memory usage, broken into wired, active, inactive, used, and free components.
Procs Total number of processes and number of processes in each process state.
SharedLibs Resident sizes of code and data segments, and link editor memory usage.
Threads Number of threads.
Time Time, in H:MM:SS format. When running in logging mode, Time is in YYYY/MM/DD HH:MM:SS format by
default, but may be overridden with accumulative mode. When running in accumulative event counting
mode, the Time is in HH:MM:SS since the beginning of the top process.
VirtMem Total virtual memory, virtual memory consumed by shared libraries, and number of pageins and pageouts.
Swap Swap usage: total size of swap areas, amount of swap space in use and amount of swap space available.
Purgeable Number of pages purged and number of pages currently purgeable.
Below the global state fields, a list of processes is displayed. The fields that are displayed depend on the
options that are set. The pid field displays the following for the architecture:
+ for 64-bit native architecture, or - for 32-bit native architecture, or * for a non-native architecture.
Я вижу следующий вывод top на Mac.Я не совсем понимаю, так как руководство не очень подробное.
Например, у меня только 8 ГБ памяти.Почему он показывает 15G PhysMem?Что такое wired, active, inactive, used, and free components?
Для дисков: числа «21281572 / 769G read» означают размер диска, считываемого с момента запуска машины?
Для сетей это числа с момента запуска машины?
Для ВМ: vsize, framework vsize, swapins, swapouts?
