 By integrating Network Watcher with Graylog, you now have a convenient and centralized way to manage and visualize network security group flow logs. Graylog has a number of other powerful features such as streams and alerts that can also be used to further manage flow logs and better understand your network traffic. Now that
 you have Graylog set up and connected to Azure, feel free to continue to explore the other functionality that it offers.
