How can VPN tunnels be monitored on a FortiGate device?

Monitoring VPN tunnels on a FortiGate device can be effectively accomplished using the FortiGate dashboard or CLI commands. The dashboard provides a graphical representation of the VPN status, showing details such as the number of active tunnels, connection status, and performance metrics. This kind of visual monitoring allows for easy identification of potential issues and overall network health.

Additionally, using CLI commands enables deeper insights into the VPN tunnels. Administrators can execute specific commands to obtain real-time information and statistics regarding the tunnels, such as encryption details, packet counts, and tunnel status. This flexibility offers comprehensive monitoring capabilities directly from the FortiGate device itself.

The use of third-party monitoring tools might provide additional features or integration but is not the only method for monitoring VPN tunnels, making it less suitable as a standalone solution for FortiGate users. Email notifications serve as an alert system but do not provide detailed monitoring capabilities, and relying solely on manual network logs can be cumbersome and inefficient compared to the automated tools available on the device.
