MONITORING VPN CONNECTIONS USING AWS HEALTH EVENTS

PDFRSS

AWS Site-to-Site VPN automatically sends notifications to the AWS AWS Health
Dashboard (PHD), which is powered by the AWS Health API. This dashboard requires
no setup, and is ready to use for authenticated AWS users. You can configure
multiple actions in response to event notifications through the AWS Health
Dashboard.

The AWS Health Dashboard provides the following types of notifications for your
VPN connections:

 * Tunnel endpoint replacement notifications

 * Single tunnel VPN notifications


TUNNEL ENDPOINT REPLACEMENT NOTIFICATIONS

You receive a Tunnel endpoint replacement notification in the AWS Health
Dashboard when one or both of the VPN tunnel endpoints in your VPN connection is
replaced. A tunnel endpoint is replaced when AWS performs tunnel updates, or
when you modify your VPN connection. For more information, see Site-to-Site VPN
tunnel endpoint replacements.

When a tunnel endpoint replacement is complete, AWS sends the Tunnel endpoint
replacement notification through a AWS Health Dashboard event.


SINGLE TUNNEL VPN NOTIFICATIONS

A Site-to-Site VPN connection consists of two tunnels for redundancy. We
strongly recommend that you configure both tunnels for high availability. If
your VPN connection has one tunnel up but the other is down for more than one
hour in a day, you receive a monthly VPN single tunnel notification through an
AWS Health Dashboard event. This event will be updated weekly with any new VPN
connections detected as single tunnel, and a new event created monthly which
will clear any VPN connections no longer detected as single tunnel.
