If your colleagues are really using guesswork, rather than thinking about the problem, then they are doing a bad job. The animation and graphics can do a lot of things nowadays.

However, with that being said, logging comes with downsides as well, such as logging too much or too little and performance issues. Personally when I run into a bug, I recheck the code, try to trace it in my mind from the program logic, because that sometimes helps me uncover other problems or side effects easier than just using the debbuger and fixing the bug where it manifests itself.

In this case you definitely want to inspect the code, while its processed. The last thing you want to do when you try to solve a bug is to waste time by troubleshooting the wrong service. Once the application is connected with the tool, the developer can start a debugging session from the main dashboard as they would normally do in a local environment. Testing and debugging, both are interdependent and one cannot be executed without the presence of other, as it is only after the successful culmination of testing that debugging can be executed by the team of developers.
