Interface Bandwidth Trends
Monitoring > Bandwidth > Overlays & Interfaces > Interface Trends
The Interface Bandwidth Trends tab shows interface statistics for a single selected appliance in real time or for a specific period. Real time charts show the past five minutes of usage and refresh every second. By default, charts display transmit and receive statistics for bandwidth and firewall denies. You can toggle peak statistics or maximum bandwidth statistics on or off by clicking the sample indicator line next to each statistic name.
You can customize the chart settings using the controls at the top of the tab, as follows:
| Option | Description |
|---|---|
| Time period | Click Real Time to enable live statistics for all available interfaces. Click a predefined time period (1h, 4h, 1d, 7d) to display statistics over the last hour, four hours, day, or seven days. Click Custom and set your own custom time range to display statistics for that time period. |
| Packets/bps | Click Packets to display statistics according to the number of packets sent and received. Click bps to display statistics for bits per second sent and received. |
| Show in UTC | Click this option to toggle chart times between local appliance time or UTC. |
| Large | Click this option to toggle the size of the charts between smaller (default) and large. |
| Lock Scale | By default, each chart uses its own scale that is relative to the data displayed. Click this option to apply and lock the same scale to each chart. |
| Payload | By default, charts show complete bandwidth usage statistics—payload plus all SD-WAN overhead (headers, FEC, and so forth). To see bandwidth usage for payload only, click to enable the Payload button. |
