description:
 This check monitors site-to-site VPN tunnels ({FW2FW} and {IPSEC}) of a
 Barracuda CloudGen Firewall, as reported by the Phion-MIB vpnTunnels
 table.

 Tunnels that consist of multiple redundant transports (paths) are
 bundled into a single service. For each transport the state {active},
 {down-disabled} or {down} is evaluated; unrecognised states are reported
 as {unknown}.

 Levels for the number of active transports can be configured via the
 ruleset "Phion/Barracuda VPN tunnels". If no levels are configured, the
 service goes {CRIT} when no transport is active, and {WARN} when at
 least one but not all transports are active.

item:
 The name of the tunnel, or of the tunnel bundle for tunnels with
 multiple redundant transports, as reported by the device.

discovery:
 One service is created for each site-to-site VPN tunnel or tunnel bundle
 reported by the device. Tunnels that are not site-to-site
 ({FW2FW}/{IPSEC}) are ignored.
