Where is Tomcat Console Output on Windows

I used to start tomcat from its bin folder with the startup.bat. By running that script it opened a java window in which I can see the outputs from tomcat. However, I've been told that this is not the right way to start tomcat on a windows server. Therefore I start tomcat now over the service program. By doing so no java window is being opened anymore and therefore I can't see the output msg from tomcat.

I have also looked into the logs folder of tomcat. Those saved outputs are not the same as the one I had/have in java window. Does anyone know where I can find those outputs?

Many thanks in advance for any advices.

There is no such thing. There is no catalina.out on MS Windows. On MS there is catalina-datetime-in-some-random-format.log but that is NOT catalina.out nor does it contain same information.

On a real operating systems there is catalina.out that contains all output from JVM both stdout and stderr. On MS windoh! ;) it is just a log file for Tomcat JUL log file (not CONSOLE/stdout/stderr). Then there are catalina-stdout.log and catalina-stderr.log files. So every single time you need to find some information on M$ you have dig through all three files. Most of contain duplicate information making it absolute hell to try to process the logs via any automation like ELK stack.

In Windows (I am using Windows 10) you should do these to check the running application's logs:-

  1. Install Notepad++
  2. Open C:\Program Files\Apache Software Foundation\Tomcat {ver}\logs\tomcat{ver}-stdout.{date}.log in Notepad++
  3. Open View menu and enable 'Monitoring' in Notepad++

Usually the logs should be in $TOMCAT_HOME/logs

When running tomcat as a service, i have noticed that Tomcat sometimes generated logs in the folder where tomcat was started from so also check $TOMCAT_HOME/bin for any possible log files.

This is why you should configure Log4j so that you have control of where the log files are created.

If we assume your install is in C:\program files\apache software foundation\apache-tomcat{ver}\

then it is inside, in the log directory, in a file catalina.out.

C:\program files\apache software foundation\apache-tomcat{ver}\logs\catalina.out

It's worth to note the name of the file depends on your configuration, also the name of the logs directory can be different depending on configuration but I assume you preserved default config.
