I'm used to looking for problems in code or in the system, using logs or monitoring indicators, which are displayed on pretty control panels with a simple and intuitive interface. However, if for some reason the data does not arrive to the control panel, or the logs of some service are unavailable, debugging becomes more complicated. Now there are few such problems, they are rare, but they do happen. Therefore, in our time is very valuable knowledge of tools that help to understand what is wrong with a certain process on any computer.
