Viewing SonicWall WAN bandwidth in real-time

To view SonicWall WAN bandwidth in real-time, you can use the real-time monitor and filter to match your desired interface. This will show you how much bandwidth is being used by that interface and which applications are utilising the bandwidth.

Alternatively, you can use GMS in distributed mode and set up a Flow Server to view this information from the GMS itself. This will allow you to see a breakdown of bandwidth usage by interface and identify what is using the traffic.

If you're looking for a more visual representation of your network bandwidth, you might want to try Cacti or Grafana (Cloud). Cacti is a free, open-source tool that specialises in creating network bandwidth diagrams. However, it requires some IaaS to run. Grafana (Cloud) is another option that provides similar functionality.

By utilising these tools and methods, you can effectively monitor and analyse your SonicWall WAN bandwidth in real-time, gaining insights into bandwidth usage per interface and the applications driving that usage.

Using GMS in distributed mode

The SonicWall Global Management System (GMS) is a powerful and intuitive solution for centrally managing and deploying SonicWall firewall, anti-spam, backup and recovery, and secure remote access solutions. GMS provides real-time monitoring and comprehensive policy and compliance reporting, helping to streamline security policy management and appliance deployment for enterprises and simplify security management for service providers.

To use GMS in distributed mode, follow these steps:

• Configure the firewall to send syslogs to GMS. Navigate to System > Administration in the firewall. For firewall firmware prior to 6.5.X.X, follow the steps under System > Administration > Advanced Management. For firewall firmware 6.5.X.X and newer, simply click Configure.
• Add the GMS IP address, which is the INTERNAL IP of the Primary GMS Console or All-in-One Internal IP.
• If GMS is behind a NAT device (i.e., across the WAN), check the "GMS Behind NAT Device" box and add the External IP of the device upstream of the server. Ensure the NAT device has the appropriate access rule and NAT policy allowing UDP 514 to the GMS Agent.
• If sending syslogs to a distributed agent, check the box for "Send Syslog Messages to a Distributed Reporting GMS Server" and add the Internal IP of that destination agent.
• Log into GMS and navigate to the Firewall Tab. Select "Add Unit".
• Add a Friendly Name, Serial Number, Admin Account, and Password. Choose SSL for the Management Mode and click OK. Ensure you add the correct port you are using to manage the firewall if it is different from the default port, 443.
• Select the AGENT IP Address of the Agent that you wish this device to report to. This can be modified later by right-clicking the firewall and selecting "modify agent", but this requires a similar change on the firewall.

Note that a typical distributed deployment consists of a Virtual Appliance or Windows server deployed as a Console or All-in-one server, with one or more of these devices deployed as Agents.

Using a Flow Server

To monitor bandwidth usage per IP address in SonicWall, you can utilise a Flow Server by following these steps:

Firstly, ensure that you have GMS (Geneva Management System) implemented with your SonicWall device. The GMS is a powerful tool that allows for centralised management and monitoring of SonicWall appliances.

Next, set up the GMS in distributed mode. This mode enables you to manage multiple SonicWall devices from a single interface, providing a comprehensive view of your network infrastructure.

Once GMS is configured in distributed mode, you can establish a Flow Server. The Flow Server acts as a central repository for network traffic data, collecting and storing information about bandwidth usage and traffic flow.

By accessing the Flow Server via the GMS interface, you can gain valuable insights into your network's performance and bandwidth consumption. The Flow Server provides real-time data, allowing you to monitor bandwidth usage per IP address. This detailed information helps you identify which applications and IP addresses are utilising the most bandwidth, enabling you to optimise your network's performance and allocate resources efficiently.

Additionally, the Flow Server offers the ability to set up alerts and notifications based on specific bandwidth usage thresholds. This feature ensures that you are proactively notified when bandwidth usage reaches a certain level, helping you to proactively manage your network and address any potential issues promptly.

By leveraging the capabilities of a Flow Server, you can effectively monitor bandwidth usage per IP address in SonicWall, making data-driven decisions to optimise your network's performance and security.
