Hello yeowkm99,

 

I found this solution, can you tell me if it helps you, please? :)

 

To generate a report on FortiAnalyzer to see which user or application is consuming a lot of bandwidth for a particular subnet, follow these steps:

  1. Access Reports: Navigate to Reports -> All Reports -> Bandwidth and Applications Report on the FortiAnalyzer.

  2. Add Filter: Click on Add Filter to specify the criteria for your report.

  3. Specify Log Field: Choose the appropriate Log Field to filter the data. For bandwidth consumption, you might want to select fields like Source IP, Destination IP, or Application.

  4. Filter by Subnet: Use the filter option to specify the subnet you are interested in. For example, enter 172.28.0.0/24 to focus on that particular subnet.

  5. Generate Report: Once the filters are set, generate the report to view the bandwidth consumption details for the specified subnet.

  6. Review and Analyze: Analyze the report to identify which users or applications are consuming the most bandwidth within the specified subnet. By following these steps, you can effectively monitor and analyze bandwidth usage for a specific subnet using FortiAnalyzer.
