You can check how many active network tunnels you have through Umbrella's Overview report, or monitor a tunnel's status in Network Tunnels under Deployments.
- Monitor Tunnel Status from Deployments
- View Number of Active Network Tunnels from Overview Report
- Cisco Catalyst SD-WAN Layer 7 Health Check
- Umbrella organization ID. For more information, see Find Your Organization ID.
- Cisco Umbrella Secure Internet Gateway (SIG) Essentials subscription or a free SIG trial.
- Navigate to Deployments > Core Identities > Network Tunnels.
- Umbrella lists your tunnels and the status of each tunnel.
- Active—Traffic is traversing the tunnel and has been logged.
- Inactive—Tunnel is established but currently has no traffic, or its traffic is not being logged.
- Unestablished—Tunnel has not yet established a connection between a network device and Umbrella.
- Unknown—Umbrella cannot determine the current status of the tunnel.
You can check how many active network tunnels you have through Umbrella's Overview page.
- Navigate to Overview.
- In the Deployment Health section, a widget lists the number of active network tunnels in your organization. When active traffic is traversing the tunnel and logging is enabled in the default cloud-delivered firewall (CDFW) policy, Umbrella displays a network tunnel as Active .
For Cisco Catalyst SD-WAN (formerly known as Viptela) devices, Umbrella supports Layer 7 health checks of the CDFW and Secure Web Gateway (SWG) service through the tunnel. Monitoring network tunnels with Layer 7 health checks helps to ensure tunnel high availability and resiliency. Cisco Catalyst SD-WAN devices support automated tunnel failover between the primary and standby tunnel depending on the result of the Layer 7 health check.
- The Layer 7 health check is restricted to the CDFW and SWG services only and a successful health check does not guarantee connectivity beyond these services to the internet.
- The URL for the health check is
http://service.sig.umbrella.com. The Umbrella health check service is only accessible through a tunnel.
