The Common Log Format is a standardized text file format used by various web servers in generating server log files. We will take a look at two popular log formats that are often utilized with Apache access logs below. As mentioned above, the format for the access logs is defined in the CustomLog directive along with the location. Making sense of the Apache access logs requires that the analyst understand the format in which the access logs are being recorded. Now that you know what Apache access logs are and where they can be found, we can explain how to interpret the entries so that your development team and other IT personnel can make good use of them. Ultimately, the location and format (more on this later) of the access logs are defined by a CustomLog directive which can be viewed and modified within your Apache HTTP server configuration. The default location may vary slightly on other Linux distributions, but you will not have to look very far in most cases. On the Ubuntu Linux distribution, for example, access log records will be written to the following location by default: So, for the purposes of this article, we will stick to detailing where the Apache access logs can be found on a Linux machine. The majority of Apache HTTP server instances run on Linux distributions. The location of the Apache access logs is dependent upon the system on which the Apache HTTP server is running. This information is valuable in a variety of situations: for example, if a common request is failing for each individual trying to get to a particular web page, the link may be pointing to a page that no longer exists if a certain page on the site is taking longer than it should to load, log entries could indicate SQL queries that could be refactored to improve performance if one particular page on the site is very popular, aggregating data from access logs could shine a light on commonly requested resources, thus enabling businesses to increase their popularity by providing more related content. So if an individual visits a webpage on your site, the access log file will contain details regarding this event. This particular log file is responsible for recording data for all requests processed by the Apache server. What are Apache Access Logs?Īs mentioned above, the Apache access log is one of several log files produced by an Apache HTTP server. Since the real power of log data comes from comprehending the meaning of the data through analysis, I will also discuss the benefits of working with a log management and analytics platform (such as Sumo Logic) to derive valuable insights from access log data. Below, I will get into the particulars of these logs: I’ll explain what gets recorded in the Apache access logs, where they can be found, and how to make sense of the data contained in the file. One specific log file that can be used in debugging applications (or simply gaining insight into visitor activity) is the access log produced by an Apache HTTP server. In fact, log files are typically utilized as the primary source of information when a website is malfunctioning. usr/bin/jsvc -user tomcat6 -cp /usr/share/java/commons-daemon.jar:/usr/share/tomcat6/bin/bootstrap.jar -outfile SYSLOG -errfile SYSLOG -pidfile /var/run/tomcat6.pidĭidn't show any log files.As any developer or system administrator will tell you, log files are an extremely useful tool for debugging issues within a web application. My Tomcat splash page reliably informs me of the following Tomcat is installed with CATALINA_HOME in /usr/share/tomcat6įollowing the rules from /usr/share/doc/tomcat6-common/. I am trying to find the logs to determine why my war won't start (I suspect low memory as i'm on a small VPS) but I don't know where they are. ![]() I uploaded a WAR using the manager interface and tried to start the application but get a pretty generic error on the Web interface saying it couldn't be started. I installed Tomcat6 on a Ubuntu 9.04 server using apt-get install tomcat6.
