Every developer needs to have a good logging tool. Unfortunately, what I see happening a lot is developers keeping up with the latest and greatest of everything, but not logging. In a way this is good, the best logging framework is the one you don't even know is working. However, if you have not used ReflectInsight from ReflectSoftware before, you are going to love this chapter. It is so incredibly important to have the right logging tool, especially in machine learning, and nothing comes close to the rich, robust logging provided by this tool!

 You absolutely need to know what's going on inside your algorithm, and ReflectSoftware has the richest logging capabilities around. Especially when it comes to machine learning algorithms, there is nothing that remotely comes close. And when you move into deep learning, you are going to be very happy you can see what is going on under the covers.

With an algorithm running for possibly days, the insights you receive from the right kind of logging are invaluable:

ReflectInsight is comprised of a Software Development Kit (SDK), a router, a Log Viewer, and a Live Viewer. We'll take up each one separately and discuss them in detail.

In this chapter, we will cover the following topics:

• Router
• Log Viewer
• Live Viewer
  • Message navigation
  • Searching through your messages
  • Time zone formatting
  • Auto Save/Purge
  • SDK
  • Configuration editor
