The SD-WAN monitor’s table view in FortiManager provides a donut visualization plus a detailed table that shows each SD-WAN member’s status and SLA pass/miss, giving the per-member health view you’re after. FortiManager templates reduce repetitive work but must resolve to valid, device-specific configurations at installation time. Device assignments, metadata mappings, ADOM scope, policy-package interfaces and provisioning order should be inspected together rather than troubleshooting any one object in isolation. A successful management connection does not guarantee a successful configuration installation. Review the installation preview and task log, then validate the resulting device configuration and operational diagnostics. This separates a deployment-time validation failure from a live tunnel, routing or SLA fault. In the relevant Fortinet FortiManager documentation, the applicable feature should be verified against the deployed software version, the selected configuration mode and the live operational state before the answer is treated as a definitive implementation requirement. The status of individual overlay interfaces can be inspected separately.
