Use data to remove overly restrictive traffic rules.Understand traffic growth for capacity forecasting.Combine with GeoIP data to identify cross-region traffic.Export flow logs to analytics and visualization tools of your choice to set up monitoring dashboards.Filter flow logs by IP and port to understand application behavior.Monitor traffic levels and bandwidth consumption.You can use them for optimizing network flows, monitoring throughput, verifying compliance, detecting intrusions, and more. Whether you're in a startup that's trying to optimize resources or a large enterprise that's trying to detect intrusion, flow logs can help. You also need to know which ports are open to the internet, what network behavior is expected, what network behavior is irregular, and when sudden rises in traffic happen.įlow logs are the source of truth for all network activity in your cloud environment. You need to know the current state of the network, who's connecting, and where users are connecting from. It's vital to monitor, manage, and know your own network so that you can protect and optimize it. Flow data is sent to Azure Storage from where you can access it and export it to any visualization tool, security information and event management (SIEM) solution, or intrusion detection system (IDS) of your choice. NSG flow logs is a feature of Azure Network Watcher that allows you to log information about IP traffic flowing through a network security group (NSG).
