How to Check Bandwidth & Top Consumer Applications in FortiPortal 7.4
Need to diagnose why users are complaining of slow internet, or identify which department is saturating your branch WAN circuit? Here is the exact step-by-step process to check real-time and historical bandwidth in FortiPortal 7.4, decode FortiView traffic graphs, and find top talkers.
Eliminate manual operational errors, decipher complex telemetry in 1 second, and save hours every single week.
📋 Step-by-Step Execution Guide
Navigate to Analytics & FortiView in FortiPortal
In your FortiPortal 7.4 left-hand navigation sidebar, click on "Analytics" and select "FortiView". Choose your target managed firewall (e.g. GATEWAY-01).
Filter by Applications & Sources (Top Talkers)
Select the "Applications" tab to see bandwidth broken down by protocol (HTTPS, SharePoint, YouTube, Cloud Backups). Click the "Bandwidth" column header to sort descending.
Distinguish Allowed Traffic Volume from Security Threats
Solid blue bars represent Allowed Traffic Volume Risk (high-bandwidth file sync), while red/orange indicates blocked malicious threats. Do not confuse high bandwidth on SharePoint with an active breach.
Check Real-Time Interface Throughput via CLI
If the GUI aggregation is delayed, run live bandwidth monitoring commands directly on FortiOS to see per-interface ingress and egress bytes.
⚡ FortiOS CLI Commands for Live Bandwidth & Throughput
# 1. Show real-time bandwidth and packet throughput per interface
diagnose ip router get-route-stats
# 2. Monitor real-time traffic flow on WAN interfaces (e.g. port1)
diagnose hardware devicenic interface port1
# 3. List top bandwidth consumer sessions active right now
diagnose sys session filter dport 443
diagnose sys session list | grep -E "bytes|proto|devname"❓ Frequently Asked Questions
Why does FortiPortal show high bandwidth but low threat scores?
Bandwidth measures total data volume transferred (bytes sent/received). If employees are uploading large CAD files or syncing SharePoint, bandwidth spikes legitimately without triggering threat signatures.
How can I tell if an interface is saturated in FortiPortal?
Compare the peak bandwidth megabits per second (Mbps) against your ISP circuit bandwidth (e.g. 100 Mbps or 1 Gbps). When bandwidth graph lines plateau at the top edge of the chart with rising latency, the link is saturated.
How does PortalPilot help troubleshoot bandwidth spikes?
PortalPilot translates raw FortiPortal session logs and FortiView graphs into plain-English summaries, instantly identifying whether a bandwidth surge is benign cloud collaboration or unapproved shadow IT.
