title: Azure VPN Gateway: BGP Tunnel
agents: azure

description:
 This check monitors a single BGP tunnel (instance) of an Azure Virtual
 Network Gateway. For every entry in the gateway's bgpSettings
 bgpPeeringAddresses one service is created, so an active-active gateway
 with two tunnels results in two independent services instead of one
 combined service.

 Each service reports the tunnel's public tunnel IP address, the default
 and custom BGP peering IP addresses and the ASN. The service is {WARN}
 when the instance has no public tunnel IP address, otherwise {OK}.

item:
 The gateway name followed by the IP configuration / instance name of the
 tunnel, for example "mygateway_default" or "mygateway_activeActive".

discovery:
 One service is created for each BGP peering address of the gateway.
