Observability Dashboards

SecureLink includes embedded Grafana dashboards that provide deep network analytics and operational visibility across your edge deployment. These dashboards are accessible directly within the SecureLink interface -- no separate login is required.

Available Dashboards​

Edge Overview​

A multi-edge summary dashboard showing aggregate metrics across all devices in your tenant.

  • Total throughput across all edges.
  • Device online/offline counts.
  • Top edges by bandwidth consumption.
  • Useful for getting a quick health check of your entire network at a glance.

Interface Detail​

Per-interface analytics for a selected edge device.

  • Bandwidth utilization (bytes in/out) with high-resolution time series.
  • Packet rates (packets per second) in and out.
  • Error rates and drop counts per interface.
  • Select specific interfaces (WAN, LAN, WireGuard tunnels) to focus the view.

WireGuard Tunnels​

Dedicated dashboard for monitoring WireGuard tunnel health.

  • Tunnel status (up/down) for all configured tunnels.
  • Handshake freshness -- how recently each peer completed a handshake.
  • Data transfer rates per tunnel.
  • Useful for monitoring VPN connectivity between edges, to peers, and to connectors.

Traffic Analysis​

Flow-level traffic analytics for edges with IPFIX/Flowprobe enabled.

  • Top talkers -- highest bandwidth source and destination pairs.
  • Protocol distribution -- breakdown of traffic by TCP, UDP, ICMP, and other protocols.
  • Flow analysis -- detailed view of individual traffic flows with source, destination, ports, and byte counts.

System Health​

Resource utilization metrics from edge devices.

  • CPU -- Processing load on the edge device.
  • Memory -- RAM usage and available capacity.
  • Disk -- Storage utilization, important for log retention and system stability.

Controls​

Time Range​

Each dashboard includes a time range selector. Choose from predefined intervals or set a custom range. The selected time range applies to all panels within the dashboard.

Auto-Refresh​

Enable auto-refresh to keep dashboards updating at a regular interval (e.g., every 30 seconds or every minute). This is useful for displaying dashboards on a monitoring screen or during active troubleshooting.

Dashboard Variables​

Use the variable dropdowns at the top of each dashboard to filter the displayed data:

  • Tenant -- Filter to a specific tenant (relevant for multi-tenant environments).
  • Edge -- Select one or more edge devices.
  • Interface -- Narrow down to a specific interface on the selected edge.

Variable selections are preserved within your session, so switching between dashboards retains your context.

info

Dashboards are powered by VictoriaMetrics as the metrics data source. Metric data is retained according to the configured retention policy. For long-term historical analysis, ensure your retention settings align with your reporting needs.
