Lab 7 - Service Mapping
Lab Overview
Services are a part of application monitoring and provide a logical view of your system. Services are derived from infrastructure entities such as hosts, containers, and processes. In this lab you will learn to modify the ratings service of Robot Shop by changing its name from rs-ratings to rs-ratings-your last name. By the end of the lab, you should be able to find your service in your Application Perspective with its new name.

Step 4:

Step 5:
