I have XAMPP, which is an Apache server installed apache access log analyzer on my machine, which automatically logs the accesses. It is stored in my installation folder. files logs syslog share|improve this question edited May 19 '12 at 12:50 Gilles 368k666671117 asked May 18 '12 at 21:51 AkshaiShah 9912108 On what distribution, or with what hosting provider? Logs are typically under /var/log, but some systems have them elsewhere. –Gilles May 19 '12 at 12:51 add a comment| 3 Answers 3 active oldest votes up vote 91 down vote accepted Ultimately, this depends on your Apache configuration. Look for CustomLog directives in your Apache configuration, see the manual for examples. A typical location for all log files is /var/log and subdirectories. Try /var/log/apache/access.log or /var/log/apache2/access.log. If the logs aren't there, try running locate access.log. share|improve this answer answered May 19 '12 at 12:54 Gilles 368k666671117 +1 for CustomLog –Radu 7 hours ago add a comment| up vote 20 down vote If you can't find the log with Gilles's answer, there are a couple more things you can try. Look in /var/log/httpd. Run sudo locate access.log as well as sudo locate access_log. The logs on my system were not visible except to root, and the file was called access_lo

Written by Louise Fahys Be the first to comment! From : http://www.cyberciti.biz/faq/apache-logs/ There are two type of apache httpd server log files: Error Logs All apache errors / diagnostic http://unix.stackexchange.com/questions/38978/where-are-apache-file-access-logs-stored information other errors found while serving requests are logged to this file. Location of error log is set using ErrorLog directive. If there is any problem, you should first take a look at this file using cat, grep or any other UNIX / Linux text utilities.

Apache stores two kinds of logs: Access Log Contains information about requests coming http://archive.oreilly.com/pub/a/sysadmin/2006/10/12/httpd-syslog.html in to the web server. This information can include what pages people are viewing, the success status of requests, and how long the request took to respond. error log It looks something like this: Apache 10.185.248.71 - - [09/Jan/2015:19:12:06 +0000] 808840 "GET /inventoryService/inventory/purchaseItem?userId=20253471&itemId=23434300 HTTP/1.1" 500 17 "-" "Apache-HttpClient/4.2.6 (java 1.5)" 1 10.185.248.71 - - [09/Jan/2015:19:12:06 +0000] 808840 "GET /inventoryService/inventory/purchaseItem?userId=20253471&itemId=23434300 HTTP/1.1" 500 17 "-" "Apache-HttpClient/4.2.6 (java 1.5)" Error Log Contains information about errors that the web server encountered when processing requests, such as when files are apache error log missing.

Apache httpd Logs to Syslog by Rich Bowen 10/12/2006 Every time your Apache server receives a request, it makes an entry to one or more logfiles. These logfiles are useful for a variety of purposes, from statistical analysis of your visitors to forensic analysis of an attack on your server. In many situations, having these logs written to a local file system is inconvenient, to say the least. Two specific scenarios come to mind, but perhaps you have others. The first is, unfortunately, one with which I have personal experience. When attackers compromise a server, they often "clean up" after themselves so that you can't figure out how they broke in. If they're careful, this includes deleting the logfiles so that you can't see what techniques they used. This is particularly true if they used the web server itself as their method of entry, but some scripted exploits simply delete all logfiles for good measure. In this case, it's very handy to have a copy of those logfiles somewhere else. The second scenario is perhaps less likely, but it is just as interesting. When you have more than one server--particularly when you have dozens or hundreds--it can become quite a chore to look at your logfiles because there are so many of them. In this case, it may be useful to combine them to a central location. In either of these cases, it is ideal to have the logfiles sent to a central syslog server, rather than having them written to the local file system. Logging to syslog As it happens, one thing that very few people know about the Apache web server is that you can log your error log to syslog with a single configuration directive: ErrorLog syslog:local1 That's almost all there is to it. This tells Apache to send the error log output to the syslog facility called local1. Of course, you also need to tell your syslog server to send this log output off to another server--your syslog server--to write it to a logfile. Exactly how you do this may vary from one syslog implementation to another. However, the normal Linux syslog uses a file called /etc/syslog.conf (or some variant thereof) to configure how syslog streams. Because the Apache error log uses syslog-standard severity ratings, you can use normal syslog configurations to split syslog output into different files based on severity. For example, if you wanted to log only critical errors to a particular file, add the line in your /etc/syslog.conf file: local1.crit /var/log/apache.crit This still causes the logging of entries of level crit and higher to the file /var/log/apache.crit. I promised that you co
