Summary

In this chapter, you’ve seen tracing and logging facilities that can help you find intermediate problems in your applications. You should plan early, building these features into your applications. This will help you avoid a lot of troubleshooting problems later.

With tracing, you can write debugging messages to an application that can also be used for the final product delivered. In case there are problems, you can turn tracing on by changing configuration values, and find the issues.

Event logging provides information to the system administrator to help find some of the critical issues with the application. Performance monitoring helps in analyzing the load from applications and in planning in advance for resources that might be required in the future.
