Lab 18 - Relating your metrics and logs

Metrics allow you to identify symptoms in your environment (WHAT is going on?). Relevant logs help you identify the cause (WHY is this happening?). Looking at our failed bookings from Lab 14, let's take a look at the relevant logs to identify why we have failed bookings.

 

  1. Follow steps 1 and 2 for Lab 14 to identify counts of successful booking and failed bookings for your travel website.
