Re: Option for machine-readable output (e.g. JSON) from top?

Hi,

As Craig mentions, you can use other programs to get all the information to=
p has in easily parsable format. To make it more palpable, here's the break=
down:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

first line:
 top - 10:43:28 up 14:23,  1 user,  load average: 1.70, 1.14, 0.87
is exactly the same as reported by uptime
 10:44:15 up 14:23,  1 user,  load average: 1.03, 1.03, 0.84

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Second line:
Tasks: 375 total,   1 running, 374 sleeping,   0 stopped,   0 zombie
is `ps`

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Third line:
%Cpu(s):  1.3 us,  1.5 sy,  0.0 ni, 95.7 id,  0.0 wa,  1.3 hi,  0.1 si,  0.=
0 st=20

is `mpstat`:

per-process memory info, niceness and other stuff can be obtained with `ps`=
.

Hope that helps in whatever project you're developing. These tools can usua=
lly be invoked as long-running daemons to avoid fork/exec spam every second=
. Moreover, many of these tools support machine-readable formats for easier=
 parsing, ex `mpstat -o JSON 1` will report JSON data.

Best,
