FIELD DESCRIPTIONS
top displays a variety of information about the processor state. The
display is updated every 5 seconds by default, but you can change that
with the d command-line option or the s interactive command.

uptime
This line displays the time the system has been up, and the three
load averages for the system. The load averages are the average
number of process ready to run during the last 1, 5 and 15 min-
utes. This line is just like the output of uptime(1). The uptime
display may be toggled by the interactive l command.

processes
The total number of processes running at the time of the last
update. This is also broken down into the number of tasks which
are running, sleeping, stopped, or undead. The processes and
states display may be toggled by the t interactive command.

CPU states
Shows the percentage of CPU time in user mode, system mode, niced
tasks, iowait and idle. (Niced tasks are only those whose nice
value is positive.) Time spent in niced tasks will also be
counted in system and user time, so the total will be more than
100%. The processes and states display may be toggled by the t
interactive command.

Mem Statistics on memory usage, including total available memory, free
memory, used memory, shared memory, and memory used for buffers.
The display of memory information may be toggled by the m interac-
tive command.

Swap Statistics on swap space, including total swap space, available
swap space, and used swap space. This and Mem are just like the
output of free(1).
