Log file into SAS Dataset

jei — Thu, 26 Oct 2017 08:41:59 GMT

Hi,

I need to convert the attached log file into dataset. The log file contains multiple delimiters such as "|" , tab, and a special character (please refer to the attached log file).

Thanks for your help in advance.

Would you be able to outline your target position for the dataset, as that would help someone being able to give you some assistance.

Hi,

I wish to have the same format of the output on the attached file.

Thank you

Log files are text. Text manipulation is done with proper tools; SAS and Excel are not proper tools for text.

So what did you try?

Looking at the file you posted in the viewer on this site it looks like text file that delimited with a |.

It is trivial to read a file that is delimited with | in SAS.

data want ;
  infile 'myfile.txt' dsd dlm='|' truncover ;
  length var1-var5 $200 ;
  input var1-var5;
run;

It does appear that one of column appears to contain a list of values delimited by something that looks like a square in the view, but even that should not be hard to deal with once you have the data in a dataset instead of a text file.

Hi @Tom

I tried the code below

DATA TEST_LOG;
    LENGTH
        STATUS           $ 13
        TIMESTAMP        8
        EVENT            $ 2577
        VAL		 8
       	;
    FORMAT
        STATUS           $CHAR13.
        TIMESTAMP        BEST14.
        EVENT            $CHAR2577.
        ;
    INFORMAT
        STATUS           $CHAR13.
        TIMESTAMP        BEST14.
        EVENT            $CHAR2577.
        ;
    INFILE 'E:\TEST.log'
	LRECL=32767
        FIRSTOBS=2
        DLMSTR='7C'x
        TRUNCOVER
		
		;
    INPUT
        STATUS           : $CHAR13.
        TIMESTAMP        : ?? BEST14.
        EVENT            : $CHAR2577.
	;
	ARRAY AR[1] EVENT;
		DO i=1 ;
		AR(i)=scan(EVENT, i, '09'X);
		END;


RUN;

and gives the output below.

If you can notice, the value whose delimiter is a tab was gone.

I tried your given code and it gives me the output below.

I want to have another column for the numeric values in var3 column - which are in the most right. In my code, these values did not appear.

So basically, I'm wishing to have like the output below.

Thank you!

@jei

Just use DLM instead of DLMSTR and add all THREE delimiters as value (a pipe, backspace, tab).

DATA TEST_LOG;
    LENGTH
        STATUS           $ 13
        TIMESTAMP        8
        EVENT            $ 100
        VAL		 8
       	;
    FORMAT
        STATUS           $CHAR13.
        TIMESTAMP        BEST14.
        EVENT            $100.
        ;
    INFORMAT
        STATUS           $CHAR13.
        TIMESTAMP        BEST14.
        EVENT            $100.
        ;
    INFILE 'c:\temp\TEST.txt'
	      LRECL=32767
        FIRSTOBS=1
        DLM='7c0809'x
        dsd
        TRUNCOVER
		
		;
    INPUT
        STATUS           : $CHAR13.
        TIMESTAMP        : ?? BEST14.
        EVENT            : $100.
        val              : best15.
	;

RUN;

Your infile actually has three delimiters:

- the pipe character

- hex 08 to separate items in the long string

- hex 09 to separate events and values within an item

So you need a do loop for the items and two different splits along these separators:

data jei;
infile '$HOME/sascommunity/jei.txt' dlmstr=CRLF dlm='|' truncover;
input
  status :$5.
  TIMESTAMP :$20.
  variablestr :$500.
  n :$1.
;
length
  event $50
  val 8
;
do i = 1 to countw(variablestr,'08'x);
  event = scan(scan(variablestr,i,'08'x),1,'09'x);
  val = input(scan(scan(variablestr,i,'08'x),2,'09'x),best.);
  output;
end;
drop i variablestr;
run;

proc print data=jei noobs;
run;

Partial result:

status      TIMESTAMP       n    event                              val

To make the data more analyzable for SAS, consider to convert the timestamp value to a SAS datetime value.
