我正在尝试绘制一些趋势图,因此我希望“简化”我在电子表格中执行的手动数据收集过程并使其轻松运行。
也就是说,我得到了这个结果,标题为Timestamp,Core#,100 - %Idle:
# sadf -d -- -P ALL -s 00:00:00 -e 01:30:00 | awk '{FS=";"} {if ($4 != -1) {print $3","$4","100 - $NF}}' | sed '1d' &>cpuresults.txt

这个,标题为Timestamp,Memory Used:

2015-08-11 06:20:01 UTC,51.98
我正试图获得这样的输出:
Timestamp,Memory,Core0,Core1,Core2,Core3

所以,正如你所看到的,它只是转置每个CPU内核的最后一行,但我看不出怎么做。此外,可能还有未来的核心。
我尝试在awk上做一个循环(使用cpucount变量作为限制),只打印最大核心数的结果,匹配两个文件的时间戳,但我没有走得太远。
你能帮我解决一下awk公式来转换CPU核心值并将它们添加到memresults.txt文件中,以便它最终作为我发布的例子吗?
谢谢!

只需将数据存储在数组中,稍后再打印:
awk -F, 'FNR==NR {data[$1] = (data[$1]?data[$1] FS $3:$3); next}
{print $0 FS data[$1]}' cpu mem
这会将cpu
文件中的所有数据存储到数组data[]
中。 data [ first column ]
不断添加第3列的内容。
然后,当您循环浏览mem
文件时,只需打印整行,然后是来自data [ 1st column ]
的对应数据。
$ awk -F, 'FNR==NR {a[$1] = (a[$1]?a[$1] FS $3:$3); next} {print $0 FS a[$1]}' cpu mem

要设置标题Timestamp,Memory,Core0,Core1,Core2,Core3
,您可以将其打印在BEGIN
块中。

将file1作为
2015-08-11 05:10:04 UTC,0,22.87
2015-08-11 05:10:04 UTC,1,15.99
2015-08-11 05:10:04 UTC,2,9.81
2015-08-11 05:10:04 UTC,3,7.95
和file2为
2015-08-11 05:10:04 UTC,52.00
您可以使用cut
和paste
,如下所示:
cut -d, -f3 file1 | paste -d, - - - - | paste -d, file2 -
使用sed '1i..'
cut -d, -f3 file1 | paste -d, - - - - | paste -d, file2 - | sed '1iheader text'
结果
header text
