Using the Dashboard to Troubleshoot

Use the dashboard to isolate whether symptoms are device-related, underlay-related, or overlay-related:

1. Start in the Device Health tab to confirm device status, availability, and resource utilization trends.

2. Move to the WAN Links tab to check for transport issues such as loss, latency, jitter, utilization, or unstable link states.

3. Review the Tunnel tab to identify degraded tunnels and correlate tunnel trends with underlay conditions.

Troubleshoot Application Performance or Site Connectivity Issues

Use this task to isolate whether an SD-WAN issue is device-related, underlay (WAN link) related, or overlay (tunnel) related.

Task 1: Validate Device Health

Confirm the device is operational and has sufficient resources before you investigate the network path.

1. Verify Device Status and Availability.

2. Review CPU Utilization and Memory Usage for abnormal spikes.

3. Check interface status to confirm uplinks are online.

Task 2: Analyze WAN Links (Underlay)

Identify whether ISP or circuit conditions are degrading the underlay.

1. Navigate to the WAN Links tab.

2. Review WAN link scorecards for high packet loss, latency, or jitter.

3. Use WAN Status Over Time to detect link flaps or outages.

4. Use the WAN Links Utilization table to identify affected ISPs or circuits.

Task 3: Inspect Tunnels (Overlay)

Validate overlay stability and confirm whether tunnel behavior correlates with underlay symptoms.

1. Navigate to the Tunnel tab.

2. Identify tunnels with reduced availability or degraded performance.

3. Correlate tunnel issues with WAN link behavior observed in the WAN Links tab.

4. Use the Tunnel Map to visually identify affected paths and regions.

Outcome

You use this layered workflow to determine whether the issue is device related, WAN link related, or tunnel related

Performance Analysis and Optimization

You use historical metrics to plan capacity and improve traffic quality across the SD-WAN environment.

Capacity Planning

You analyze historical trends to:

• Identify consistently high bandwidth utilization

• Determine whether WAN links or tunnels need upgrades

• Validate whether current resources meet traffic demands

Traffic and Quality Optimization

By comparing performance metrics across links and tunnels, you can:

• Identify the best-performing ISPs

• Validate SD-WAN path selection behavior

• Ensure traffic uses optimal paths based on latency, jitter, and loss

SLA Validation and ISP Performance Monitoring

You use WAN link metrics to verify provider performance and support SLA conversations.

Verifying ISP Performance

You use the WAN Links dashboard to:

• Monitor packet loss, latency, and jitter per ISP

• Compare current and average metrics against SLA thresholds

• Identify underperforming providers

You can use this data to:

• Escalate issues with ISPs

• Support SLA discussions and renewals

• Justify provider changes or link upgrades

Operational Reporting and Stakeholder Communication

You use dashboard views to communicate status, impact, and trends to both technical and non-technical stakeholders.

Internal and External Reporting

You can use dashboard views to:

• Share real-time network health with operations teams

• Provide management with high-level availability and performance insights

• Support incident post-mortems using historical data

The combination of scorecards, charts, and tables makes it easy to communicate both high-level status and technical details.

Vendor-Agnostic Visibility

You use a consistent operational view to scale monitoring as additional SD-WAN vendors are onboarded.

Although Unified Assurance currently supports Cisco Meraki devices, the dashboard is structured to provide:

• Consistent metrics across vendors

• A unified operational view

• Simplified monitoring as additional SD-WAN vendors are onboarded

This allows you to scale SD-WAN environments without changing operational workflows.
