scanning a log file and creating results

[VDD]

I would like to extract the record count, dataset name, year and month from log files into a SAS dataset.

An example of a log after SAS has finished processing is below.  How can I achieve the requested information by examine saved logs.

Thank you for your assistance.

Sending the log to an external text file and then parsing it from there might be an option?

http://support.sas.com/documentation/cdl/en/basess/58133/HTML/default/viewer.htm#a001330273.htm

[Reeza]

And take a quick look at PROC SCAPROC and see what it returns for you. For log parsing tools, search lexjansen.com for code samples, you may have to do some digging to find one that's suitable. You could also try searching on GitHub.

Thank you @Reeza and @Anthony45 for the suggestions. 

While the proc scapproc may work well it currently doesn't fulfill my needs at least with my current understand of the process.

I did get this to work as a chucky dataset.

%let myfile "&path.\&file..log";
data junk;
	length junk $255. month $2. year $4. records 8.;
	infile &myfile.;
	input @1 junk $255.;
	test = substr(junk,1,17);
	if test = "NOTE: There were ";
	delims = ' ,.!:';               
	numWords = countw(junk, delims); 
        filename = scan(junk,numWords, delims);
	word2=scan(junk,4,delims);
	records = word2;
	delims = '_';
	numWords = countw(filename,delims);
	mon = scan(filename,numWords,delims);
	year = substr(mon,1,4);
	month = substr(mon,5,2);
	output;
	drop test mon junk word2 numwords delims;
run;

 proc print data=junk2;
 run;

Since you're already reading the dictionary table to get the list of data set names, seems like it might be easier to use the dictionary table to create a data set with the names and record counts, rather than parse the log.

You don't need to upcase() libname or memname because they are stored upper case, and adding upcase() can sometimes slow down queries, because it can't use indexes (I believe, haven't tested recently).  

create table want as
  select memname, nlobs
  from dictionary.tables
  where libname="TEST"
  and memname like "COMPARE_%"
;

[VDD]

Thank you @Quentin that would be perfect for those users whom have access to the datasets paths. 

But, some users may not have data access, where those users roles may be to only read and process logs for them to create reports for auditing review.  

What I have gets me started, but will need a lot of tailoring for future continues usage reading other log statements.

thank you all for your replies.

[Quentin]

Fair enough.  On a related note, I wrote a paper about monitoring record counts in a SAS job, for similar QC. https://www.lexjansen.com/nesug/nesug11/ds/ds06.pdf

It's a macro, you pass it a list of data sets, and it gives you a little report on record counts. 

%macro ReportObs
 (data= /*space delimited list of data set names*/
 ,out= /*optional name of output data set*/
 ,lib=work
 )
;
proc sql;
 %if %superq(out) ne %str() %then %do;
 create table &out as
 %end;
 select memname as Data
 ,memlabel as Label
 ,nlobs as nObs
 from dictionary.tables
 where libname=%upcase("&lib") and indexw (%upcase("&data"),memname)
 order by indexw (%upcase("&data"),memname)
 ;
quit;
%mend ReportObs;

It's designed to help detect when records have been accidentally deleted.  But it's also useful just for writing a little human-readable report of key record counts at the end of a SAS job.  I typically send the report to the log rather than output.

But yeah, if the goal is to show that the 'official' counts written by SAS in various log notes are correct, log parsing makes sense.
