Diagnostics
The Diagnostics page (/admin/diagnostics) provides system health monitoring and troubleshooting tools.
Displays the current state of the WireGuard interface:
| Field | Description |
|---|---|
| Interface | Interface name (default: wg0) |
| Status | Enabled or disabled |
| IPv4 Network | Configured IPv4 tunnel subnet |
| IPv6 Network | Configured IPv6 tunnel subnet |
| Endpoint | Public endpoint address and port |
Lists all WireGuard peers that have had a recent handshake, sourced from the database. The table shows:
| Column | Description |
|---|---|
| Device Name | Friendly name of the device |
| Public Key | WireGuard public key |
| IPv4 | Tunnel IP address |
| Remote IP | Client's real IP address (from last handshake) |
| Last Handshake | Timestamp of most recent handshake |
| RX / TX | Traffic statistics |
This view is useful for verifying which devices are actively connected to the VPN.
WireGUI periodically performs outbound connectivity checks to verify the server has internet access. Results are displayed in a table showing:
- Timestamp - When the check was performed
- URL - The endpoint tested
- Status - HTTP status code
- Response - Response details or error message
These checks help diagnose issues where the VPN server itself has lost upstream connectivity.
Displays recent system notifications such as:
- Interface state changes
- Peer configuration events
- Error conditions
- Background task status updates
Notifications are stored in-memory and reset on application restart.
