Logging is a type of instrumentation that's made available by the system, its various components, or the infrastructure layer. Logging is a way to gather certain or relevant data that pertains to the system. This data is also known as logs. Logs can be of any type or as per the requirements—for example, information logs, error logs, and warning logs. Sometimes, logs may be custom logs. With the help of these logs, we can analyze the faults, crashes, or processes of any task that is performed by our system. This analysis helps us fix the problems in the system.

In this section, we will look at the challenges of logging and then discuss some strategies to reach a solution for these challenges.
