Performance Charts
Performance Charts give you visual insight into the throughput and health of your edge network interfaces over time. Use these charts to monitor bandwidth usage, identify congestion, and track packet-level statistics across your deployment.
Interface Throughput
Throughput charts display bytes in and bytes out for each interface on your edges. Data is sourced from VPP interface counters reported in the 60-second inform cycle.
- Line charts plot throughput over time, making it easy to spot trends, spikes, and drops.
- Area charts show interface utilization, helping you understand how much of available capacity is in use.
Each interface (WAN, LAN, WireGuard tunnels) is charted independently so you can correlate traffic patterns across different network segments.
Packet Counters
In addition to byte-level throughput, you can view packet-level statistics:
- Packets In / Packets Out -- Total packet counts per interface.
- Errors -- Packets that encountered transmission or reception errors.
- Drops -- Packets dropped by VPP due to policy, buffer exhaustion, or other conditions.
Packet error and drop counters are particularly useful for diagnosing interface-level issues that may not be visible from throughput data alone.
Time Range Selection
Use the time range selector to control the window of data displayed:
| Range | Use Case |
|---|---|
| 1 hour | Troubleshooting an active issue |
| 6 hours | Reviewing a recent incident window |
| 24 hours | Identifying daily traffic patterns |
| 7 days | Weekly trend analysis |
| 30 days | Long-term capacity planning |
| Custom | Select a specific start and end time |
The 24-hour view is especially useful for identifying traffic patterns and peak usage times. Run it over a typical business day to understand your baseline, then use that as a reference when investigating anomalies.
Per-Edge Telemetry
When managing multiple edges, you can select specific devices to compare side by side. This is useful for:
- Comparing traffic loads across branch offices.
- Identifying an edge that is handling disproportionately more traffic.
- Verifying that a newly deployed edge is receiving expected traffic levels.
Use the edge selector dropdown to add or remove devices from the chart view.
Tooltips and Formatting
Hover over any data point to see a tooltip with exact values at that moment in time. Tooltips display timestamps formatted according to your configured timezone preference (configurable under Settings > Date & Time).
Values are displayed in human-readable units (e.g., KB/s, MB/s, GB/s) and automatically scale based on magnitude.
Exporting Data
To analyze performance data outside of SecureLink, use the Export option available on each chart. Exported data is provided in CSV format, suitable for import into spreadsheet applications or external monitoring tools.
