Why Network Visibility Has Changed

Traditional MPLS networks were largely invisible to IT teams beyond basic ping and traceroute. You knew a circuit was up or down — but had no view of application performance, bandwidth consumption by application, or whether users were actually experiencing problems.

SD-WAN inverts this. Every modern SD-WAN platform captures rich telemetry including:

  • Per-application bandwidth consumption in real time
  • WAN link quality metrics (latency, jitter, packet loss) per-path
  • Session counts and connection state
  • Traffic routing decisions and path changes
  • Security events and blocked connections

Peplink InControl: Built-in Visibility

Peplink's InControl 2 cloud management platform provides multi-site visibility out of the box:

  • Live dashboard: All sites, WAN status, and alert summary on one screen
  • Per-site WAN health graphs: Historical latency, jitter, packet loss per link
  • Application usage reports: Top apps by bandwidth across the fleet
  • SpeedFusion status: Tunnel health and active path count
  • Client tracking: Device count and top consumers per site

Key Metrics to Monitor

WAN Link Health

  • Latency (RTT): Alert at >100ms for primary links, >150ms for cellular
  • Jitter: Alert at >30ms — causes VoIP quality degradation
  • Packet loss: Alert at >1% — serious impact on TCP throughput
  • Bandwidth utilisation: Alert at >80% sustained — time to upgrade or load-balance

Application Performance

  • Microsoft 365 latency: Monitor RTT to M365 front door (<30ms target)
  • DNS resolution time: Indicator of broader connectivity issues
  • VoIP MOS scores: Measure actual call quality, not just connectivity
  • SaaS availability: Is Teams/Salesforce/ERP reachable from each site?

Security Events

  • Blocked application or destination counts
  • Firewall hit rates — sudden changes suggest anomalous traffic
  • ZTNA failed authentication attempts
  • Unusual traffic volumes from specific sites or users

Alerting Best Practices

Tiered Alert Severity

  • Critical: Site offline, primary WAN down, security breach — immediate response
  • Warning: WAN degradation, high latency, approaching capacity — response within 2 hours
  • Informational: Failover occurred (and resolved), unusual traffic pattern — review daily

Alert Fatigue Prevention

  • Set minimum duration thresholds — don't alert on 30-second spikes
  • Suppress alerts during known maintenance windows
  • Route Critical alerts to PagerDuty/OpsGenie for after-hours response
  • Group related alerts — don't send 50 alerts when a site loses internet

Reporting for Business Stakeholders

Monthly Network Health Report

  • Uptime percentage per site vs SLA target
  • Number of failover events and causes
  • Top bandwidth consumers — sites and applications
  • Open incidents and resolution times

Capacity Planning Report (Quarterly)

  • Bandwidth utilisation trends — are sites approaching limits?
  • Application growth — which apps are consuming more over time?
  • Recommendations for circuit upgrades or policy changes

Integrating with Existing Tools

  • SIEM (Splunk, Microsoft Sentinel): Forward SD-WAN syslog for security correlation
  • ITSM (ServiceNow, Freshservice): Auto-create tickets from critical SD-WAN alerts
  • Slack/Teams: Push alert notifications to ops channels
  • Grafana: Custom dashboards pulling SD-WAN APIs for executive reporting

The 24/7 Monitoring Question

SD-WAN visibility is only valuable if someone is watching. Most Australian IT teams work business hours — which means:

  • Overnight outages go undetected until staff arrive
  • Degradation affecting night-shift or international workers isn't caught
  • Proactive capacity planning requires someone reviewing reports regularly

Managed SD-WAN services like those offered by Affinity MSP address this with a 24/7 Network Operations Centre that responds to alerts in real time, regardless of time zone.

Affinity MSP: 24/7 Visibility and Response

Affinity MSP provides comprehensive SD-WAN monitoring:

  • 24/7 NOC: Australian-based engineers monitoring your network around the clock
  • Proactive response: Issues addressed before you notice them
  • Monthly reporting: Business-ready reports with trends and recommendations
  • Customer portal: Your own real-time view into every site

Conclusion

Network visibility is no longer a luxury for Australian businesses — it's the foundation of proactive IT management. SD-WAN delivers the telemetry; your job is to act on it. Whether you build internal monitoring capability or engage an MSP for 24/7 coverage, the data from your SD-WAN platform is the most valuable operational resource your IT team has.
