Pt-align,

Pt-align,

The pt-align function is very simple. It outputs the output of other tools by column.

Usage:

Pt-align [FILES]

If no file is specified, the standard input content is read by default.

 

For example, if the output of common vmstat is used, the reading experience is not user-friendly.

# vmstat 2 5procs -----------memory---------- ---swap-- -----io---- -system-- -----cpu------ r  b   swpd   free   buff  cache   si   so    bi    bo   in   cs us sy id wa st 0  0   8948 18762860 628844 3925456    0    0     1    22    0    0  0  0 100  0  0 0  0   8948 18762484 628844 3925456    0    0     0     0  174  265  0  0 100  0  0 0  0   8948 18762936 628844 3925452    0    0     0     0  217  312  0  0 100  0  0 1  0   8948 18762424 628844 3925452    0    0     0     0  218  475  0  0 100  0  0 0  0   8948 18762700 628844 3925448    0    0     0     0  181  278  0  0 100  0  0

 

In this case, you can use pt-align for processing.

# vmstat 2 5 | pt-align r b swpd     free   buff   cache si so bi bo  in  cs us sy  id wa st2 0 8948 18762356 628844 3925436  0  0  1 22   0   0  0  0 100  0  00 0 8948 18759116 628844 3925428  0  0  0  0 298 352  0  0 100  0  00 0 8948 18759160 628844 3925428  0  0  0  0 206 320  0  0 100  0  00 0 8948 18759052 628844 3925432  0  0  0  0  71 176  0  0 100  0  01 0 8948 18758924 628844 3925436  0  0  0  0 158 433  0  0 100  0  0
