Shulou(Shulou.com)06/02 Report--

This article mainly introduces "instance analysis of log files under the tomcat logs directory". In daily operation, I believe that many people have doubts about the case analysis of log files under the tomcat logs directory. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "instance analysis of log files under the tomcat logs directory". Next, please follow the editor to study!

Each time tomcat starts, the following log files are automatically produced in the logs directory and automatically backed up by date. It can help us find mistakes better.

1 、 catalina. Date .log

1. It mainly records the information when tomcat starts.

2. Startup JVM parameters and operating system and other log information

3. No log mechanism such as log4j is used, and the error messages and print statements of the system are also recorded in this log file.

4. All logs under linux are in catalina.out.
