Linux - Transpose rows into column

hello,
I have a server that collect some performance statistics of 4 servers in the following input file :

Code:
$ cat inputfile
Time,A,Server1,KPI1,data1
Time,A,Server1,KPI2,data2
Time,A,Server1,KPI3,data3
Time,A,Server1,KPI4,data4
Time,A,Server1,KPI5,data5
Time,A,Server2,KPI1,data6
Time,A,Server2,KPI2,data7
Time,A,Server2,KPI3,data8
Time,A,Server2,KPI4,data9
Time,A,Server2,KPI5,data10
Time,A,Server3,KPI1,data11
Time,A,Server3,KPI2,data12
Time,A,Server3,KPI3,data13
Time,A,Server3,KPI4,data14
Time,A,Server3,KPI5,data15
Time,A,Server4,KPI1,data16
Time,A,Server4,KPI2,data17
Time,A,Server4,KPI3,data18
Time,A,Server4,KPI4,data19
Time,A,Server4,KPI5,data20

Ild like to convert this input file (using bash or perl script) to 4 output files (for each server) and the output will be as following

Code:
$ cat Server1.csv
Time,KPI2,KPI4,KPI5
Time,data2,data4,data5

$ cat Server2.csv
Time,KPI2,KPI4,KPI5
Time,data6,data9,data10

$ cat Server3.csv
Time,KPI2,KPI4,KPI5
Time,data12,data14,data15

$ cat Server4.csv
Time,KPI2,KPI4,KPI5
Time,data17,data19,data20

thanks in advance

Welcome Captain25,

I have a few to questions pose in response first:-
  • What have you tried so far?
  • What output/errors do you get?
  • Have you searched the board yet? There are several threads asking the same thing.
  • What OS and version are you using?
  • What are your preferred tools? (C, shell, perl, awk, etc.)
  • What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.


We're all here to learn and getting the relevant information will help us all.


Kind regards,
Robin

Hello
• What have you tried so far? ……I tried to create a scripts basing on some scripts that transpose rows to columns posted on this forum.
• What output/errors do you get? ……No error, but the output was not conform as what I need
• Have you searched the board yet? There are several threads asking the same thing ……… even on other forums
• What OS and version are you using? Redhat GNU/Linux
• What are your preferred tools? (C, shell, perl, awk, etc.) ……… shell or perl
• What logical process have you considered? (to help steer us to follow what you are trying to achieve) to be more clear :

I have an input file that contain the following data:

Code:
$ cat inputfile
Time,A,Server1,KPI1,data1
Time,A,Server1,KPI2,data2
Time,A,Server1,KPI3,data3
Time,A,Server1,KPI4,data4
Time,A,Server1,KPI5,data5

Time,A,Server4,KPI2,data17
Time,A,Server4,KPI3,data18
Time,A,Server4,KPI4,data19
Time,A,Server4,KPI5,data20

I’ld like to convert this input file (using bash or perl script) to 4 output files (for each server) and the output will be as following

Code:
$ cat Server1.csv
Time,KPI2,KPI4,KPI5
Time,data2,data4,data5

$ cat Server4.csv
Time,KPI2,KPI4,KPI5
Time,data17,data19,data20

thanks in advance

Here's some Perl code that appears to accomplish what you want.
It is based, however, on assumptions that part of your output is hard-coded, your input file is sorted by server name etc.

Code:
$ 
$ cat inputfile
Time,A,Server1,KPI1,data1
Time,A,Server1,KPI2,data2
Time,A,Server1,KPI3,data3
Time,A,Server1,KPI4,data4
Time,A,Server1,KPI5,data5
Time,A,Server2,KPI1,data6
Time,A,Server2,KPI2,data7
Time,A,Server2,KPI3,data8
Time,A,Server2,KPI4,data9
Time,A,Server2,KPI5,data10
Time,A,Server3,KPI1,data11
Time,A,Server3,KPI2,data12
Time,A,Server3,KPI3,data13
Time,A,Server3,KPI4,data14
Time,A,Server3,KPI5,data15
Time,A,Server4,KPI1,data16
Time,A,Server4,KPI2,data17
Time,A,Server4,KPI3,data18
Time,A,Server4,KPI4,data19
Time,A,Server4,KPI5,data20
$ 
$ perl -F, -lane 'BEGIN { @occurrences = (2, 4, 5);
                      $prefix = "Time";
                      %active = map {$_ => 1} @occurrences;
                      $header = join ",", ($prefix, map {"KPI".$_} @occurrences);
                  }
                  if ($F[2] ne $prev) {
                      $counter = 1;
                      if ($output) {print FH $output}
                      open(FH, ">", $F[2].".csv");
                      print FH $header;
                      $output = $prefix;
                  } elsif ($active{$counter}) {
                      $output .= ",".$F[4];
                  }
                  $prev = $F[2];
                  $counter++;
                  END {print FH $output}
                 ' inputfile
$ 
$ find . -name "*.csv"
./Server2.csv
./Server3.csv
./Server4.csv
./Server1.csv
$ 
$ cat Server1.csv
Time,KPI2,KPI4,KPI5
Time,data2,data4,data5
$ 
$ cat Server2.csv
Time,KPI2,KPI4,KPI5
Time,data7,data9,data10
$ 
$ cat Server3.csv
Time,KPI2,KPI4,KPI5
Time,data12,data14,data15
$ 
$ cat Server4.csv
Time,KPI2,KPI4,KPI5
Time,data17,data19,data20
$ 
$

If it doesn't work for your input file then post a sample of your real-world input data and the output desired from that real-world data.

Hello,

thank you durden_tyler for your answer, your perl script work perfectly but it’s static, and I’ld like to have a dynamic script file to use it on a cronjob (every 5min) to collect the following KPIs:
dynamic script mean that the KPI and server name and time need to be collected from the input file.

Code:
Inputfile= counter_2017072516

KPI2= Used Physical Mem MB %, (4th position data on the line)
KPI4= Total CPU Usage of tcs SERVER Component %,
KPI5= Total CPU Usage of tcs Node %,

Server1= m07tcs1
Server2= m05tcs2
Server3= m04tcs3
Server4= m07tcs4

Time=2017-07-25 16:46:04 (dynamic)

Code:
$ cat counter_2017072516
2017-07-25 16:46:04,m07tcs1,SERVER@m07tcs1,Used Physical Mem MB,5
2017-07-25 16:46:04,m07tcs1,SERVER@m07tcs1,Used Physical Mem %,29
2017-07-25 16:46:04,m07tcs1,SERVER@m07tcs1,Used Heap Mem MB,9662
2017-07-25 16:46:04,m07tcs1,SERVER@m07tcs1,Total CPU Usage of tcs SERVER Component %,0.0
2017-07-25 16:46:04,m07tcs1,SERVER@m07tcs1,Total CPU Usage of tcs Node %,0.67

2017-07-25 16:46:04,m05tcs2,SERVER@m05tcs2,Used Physical Mem MB,6.4
2017-07-25 16:46:04,m05tcs2,SERVER@m05tcs2,Used Physical Mem %,28
2017-07-25 16:46:04,m05tcs2,SERVER@m05tcs2,Used Heap Mem MB,666
2017-07-25 16:46:04,m05tcs2,SERVER@m05tcs2,Total CPU Usage of tcs SERVER Component %,0.0
2017-07-25 16:46:04,m05tcs2,SERVER@m05tcs2,Total CPU Usage of tcs Node %,1.65

2017-07-25 16:46:04,m04tcs3,SERVER@m04tcs3,Used Physical Mem MB,8
2017-07-25 16:46:04,m04tcs3,SERVER@m04tcs3,Used Physical Mem %,15
2017-07-25 16:46:04,m04tcs3,SERVER@m04tcs3,Used Heap Mem MB,366
2017-07-25 16:46:04,m04tcs3,SERVER@m04tcs3,Total CPU Usage of tcs SERVER Component %,0.0
2017-07-25 16:46:04,m04tcs3,SERVER@m04tcs3,Total CPU Usage of tcs Node %,04

2017-07-25 16:46:04,m07tcs4,SERVER@m07tcs4,Used Physical Mem MB,13
2017-07-25 16:46:04,m07tcs4,SERVER@m07tcs4,Used Physical Mem %,45.5
2017-07-25 16:46:04,m07tcs4,SERVER@m07tcs4,Used Heap Mem MB,778
2017-07-25 16:46:04,m07tcs4,SERVER@m07tcs4,Total CPU Usage of tcs SERVER Component %,1.0
2017-07-25 16:46:04,m07tcs4,SERVER@m07tcs4,Total CPU Usage of tcs Node %,0.8

The output files need to be like

Code:
$ cat m07tcs1_2017072516.csv
Time, Used Physical Mem %, Total CPU Usage of tcs SERVER Component %, Total CPU Usage of tcs Node %
2017-07-25 16:46:04,29,0.0,0.67

$ cat m05tcs2_2017072516.csv
Time, Used Physical Mem %, Total CPU Usage of tcs SERVER Component %, Total CPU Usage of tcs Node %
2017-07-25 16:46:04,28,0.0,0.4

$ cat m04tcs3_2017072516.csv
Time, Used Physical Mem %, Total CPU Usage of tcs SERVER Component %, Total CPU Usage of tcs Node %
2017-07-25 16:46:04,15,1.0,04

$ cat m07tcs4_2017072516.csv
Time, Used Physical Mem %, Total CPU Usage of tcs SERVER Component %, Total CPU Usage of tcs Node %
2017-07-25 16:46:04,45.5,1.0,0.8

So, what have you tried to achieve this? If you show us your code so far then we can suggest changes to help. That way, we're not just writing code that you don't understand and can't support and we can see what other things your description might be missing.

Giving us something that doesn't work along with the output/errors and the desired output from real input would be very useful. We're all here to learn, after all.



Thanks again,
Robin
