Re: Parsing through an Apache Log File?

Hello everyone! I've been given the responsiblity of coding an apache access_log parser. What my tasks are to do is to return the number of hits for certain file extensions that happen on certain dates with specific IP address. As of now I'm only going back 7 days in the log looking for this information and I'm only looking for 5 file types (.doc, .pdf, .html, .php, and .flv). I'm using the fgets() function so I can read the file line by line and do the matches that I need to do and increment the counters as needed. Right now I have 3 loops looking for everything, which seems to me not to be the best way of doing this. I've also encountered that a line may have the file extension I want but it's actually the soucre of another file. (see below for example) Log file example: I want the first line but not the second line. The second line has a .css file which was used by the .html file therefore I don't want this line. I do want the first line that all it has is .html and no other files. 10.25.40.64 - - [01/Jan/2006:07:33:18 -0600] "GET /home.html HTTP/1.1" 200 8220 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 10.25.40.64 - - [01/Jan/2006:07:33:18 -0600] "GET /styles/redesign.css HTTP/1.1" 200 2381 "http://wfmu.wfm.pvt/home.html" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" At any rate, here's some of my psudo code/code for what I'm trying to accomplish. I know there has to be a better way for this and I'm looking for suggestions! <snip>

Save yourself a ton of work. Dump the raw logs into a db, and you can do all the queries on the db. Something like this... CREATE TABLE rawLogs ( ipAddress int(15) NOT NULL default '0', rfcIdentity varchar(32) NOT NULL default '', apacheUser varchar(32) NOT NULL default '', date int(15) NOT NULL default '0', request longtext NOT NULL, statusCode varchar(32) NOT NULL default '', sizeBytes int(11) NOT NULL default '0', referer longtext NOT NULL, userAgent longtext NOT NULL, KEY ipAddress (ipAddress), FULLTEXT KEY search (request,referer,userAgent) ) TYPE=MyISAM; -- John C.
