Logging & Monitoring

Logging

Most software developers neglect the significance of logs in resolving software issues. However, the fact is, logs are indispensable when it comes to addressing software bugs and helping the developers to know the health status of the application. Also, logs are pivotal to the performance of an application.

Logging, simply put, is the idea of recording events that occur within the software, in an API context logging events helps in inspecting all the requests and responses that happen in it. We can add logs to a function, a controller or any unit that needs to record events that occurred during its execution.

If not done carefully, the addition of logs can add a handful of milliseconds to the application response time.

Logging can be achieved throughout a multitude of tools like Sentry and Loggly, along side libraries such as morgan and winston to name a few.
