Monitor SD-WAN Application and Link Performance
Monitor your VPN clusters by viewing the health status
of applications and links.
Monitor the application and link performance
in your VPN clusters to troubleshoot issues by viewing summary information
across all VPN clusters and then successively drilling down to isolate
the issues to affected sites, applications, and links. Visibility
on SD-WAN traffic is shown on the SD-WAN firewall receiving the
traffic. For example, for traffic from the hub firewall to the branch
firewall, the SD-WAN monitoring data is reflected on the branch
firewall. The landing dashboard displays:
- App Performance
- Impacted—One or more applications in the VPN cluster for which none of the paths have jitter, latency, or packet loss performance that meet the specified thresholds in the Path Quality Profile in the list of paths from which the firewall can choose.
- OK—Number of VPN clusters, hubs, and branches that are experiencing no jitter, latency, or packet loss performance issues.
- Link Performance
- Error—One or more sites in the VPN cluster have connectivity issues such as when a tunnel or a virtual interface (VIF) is down.
- Warning—Number of VPN clusters, hubs, and branches that have links with jitter, latency, or packet loss performance measurements that exceed the moving seven-day average value of the metric.
- OK—Number of VPN clusters, hubs, and branches that are experiencing no jitter, latency, or packet loss performance issues.
From the landing dashboard, narrow
the view to impacted applications or links that have the Error or Warning
status. Then select an affected site to view site-level details.
From the site, view application-level or link-level details.
- Select to view at-a-glance health status summaries of your VPN clusters, hubs, and branches.
- Click an App Performance or Link Performance summary that indicates Impacted, Error, or Warning counts to view a detailed list of sites and their status based on latency, jitter, and packet loss.
- Click a site that displays Warning or Error to see one VPN cluster. The site data display App Performance and Link Performance, including the impacted applications. Additionally, use the Sites filter to view VPN clusters based on link notifications, latency deviations, jitter deviations, packet loss deviations, or impacted applications.ClickPDF/CSVto export the detailed health information for the applications and links in the Site in PDF or CSV format
- Click the branch or hub that has an application that needs attention.
- Click an impacted application to view application-level or link-level details.
