Unfortunately none of my processes have hold of a log file It could mean that the process could not open the log file. Using apt-get to install Tomcat means that it's configured to run as a daemon using jsvc. The snippet returned the output at the bottom of my question Comment formatting is unreadable.

The question as posted is referring to a Linux Ubuntu specifically installation. The answer you gave is for a Windows-based installation. Also, this question already has an accepted answer. For folks who might have gotten here from a Google search for "Tomcat log directory", this answer is actually MORE helpful than the accepted answer!

The output of the latter one is usually captured into a file, such as catalina. Thus you end up with two copies of the same messages. Consider removing FileHandler s for the applications that you do not use.
The handlers by default use the system default encoding to write the log files. It can be configured with encoding property. See Javadoc for details. This section explains how to configure Tomcat to use log4j rather than java. Note : The steps described in this section are needed when you want to reconfigure Tomcat to use Apache log4j for its own logging.
These steps are not needed if you just want to use log4j in your own web application. Download or build tomcat-juli. See Additional Components documentation for details. This tomcat-juli. It contains the full Apache Commons Logging implementation and thus is able to discover the presense of log4j and configure itself.
This log4j configuration mirrors the default java. Each file is rolled-over once per day. You can and should be more picky about which packages to include in the logging. Tomcat defines loggers by Engine and Host names.
For example, for a more detailed Catalina localhost log, add this to the end of the log4j. Note that there are known issues with using this naming convention with square brackets in log4j XML based configuration files, so we recommend you use a properties file as described until a future version of log4j allows this convention. This level should be used sparingly when debugging of internal Tomcat operations is required. Your web applications should certainly use their own log4j configuration.
This is valid with the above configuration. You would place a similar log4j. Then specify your package level logging. This page is intended only as a bootstrapping guide. This exposes log4j libraries to the web applications through the Common classloader. See class loading documentation for details. Because of that, the web applications and libraries using Apache Commons Logging library are likely to automatically choose log4j as the underlying logging implementation.
The java. DailyRollingFileAppender log4j. PatternLayout log4j. Loggly provides the infrastructure to aggregate and normalize log events so they are available to explore interactively, build visualizations, or create threshold-based alerting. In general, any method to send logs from a system or application to an external source can be adapted to send logs to Loggly. The following instructions provide one scenario for sending logs to Loggly. You can send your Tomcat application server log files to Loggly using this guide.
This guide assumes you use Tomcat 6, 7 or 8, the default java. If not, it will not correctly process multiline stack traces, for that you need to switch to Java Log4j and syslog. For alternatives, please see the Advanced Tomcat Logs Options section. Run our automatic configure-tomcat script below to setup tomcat logging and send the logs to Loggly through your syslog daemon. Alternatively, you can follow our manual configuration instructions below. You will need to enter your system root password so it can update your rsyslog configuration.
It will then prompt for your Loggly password. Search Loggly for events with the Tomcat tag over the past hour. It may take a few minutes to index the event. Alternatively, you can Manually Configure Rsyslog or Syslog-ng. It will be easier for rsyslog to find the files without dates in the names.
