[mrtg] Re: Regexp statement for parsing the logfile?..

[brandon.baker]

Richard,

I don't use regexp.  But here is how I parse the log file in perl.


open(LOG,"$mrtgdir_dir\\$logfile") or next;  #opens each logfile
       	for $linedata (<LOG>) {
    	 	 my ($rawtime,$rawin,$rawout,$rawmaxin,$rawmaxout) = split(/
/,$linedata);   #Get's values out of each line of logfile
}

Subject: [mrtg] Regexp statement for parsing the logfile?..


Greetings:

I'm trying to parse the .log files from MRTG in a PERL script using regexp,
and I'm having some difficulty.. I'd like to parse the file, and put the
datestamp, first, and second values into variables for further processing..

This is the regexp statement I'm using, and I'm not getting the results I
expected.. 

if ($_=~/(.*)\s{1,}(.*)\s{1,}(.*)\s{1,}(.*)\s{1,}(.*)/)

For instance:

shaggy:~ # cat /usr/local/apache/htdocs/nettrace/prddbs/dbquery-tbsprd.log |
./test.pl | more
