Monitor a peering connection

Each VPC keeps graphs of its peering connections: how much traffic comes in and goes out through the tunnel, and whether the tunnel was up. Use them to confirm that a new connection carries traffic, or to find when a connection dropped.

Before you begin

• A VPC with a peering connection. See Peer two VPCs.

Open the graphs

1. Open Network > VPC, select the VPC, and open its Monitoring tab.
2. Under Peering Connection, choose the connection to show.
3. Under Time Range, choose how far back to look: Last Hour, Last 6 Hours, Last 12 Hours, Last 24 Hours, or Last 1 Week.

Read the graphs

• Inbound Traffic is the traffic that reached this VPC through the tunnel.
• Outbound Traffic is the traffic this VPC sent through it.
• Tunnel Activity shows whether the tunnel was up: 1 means active, and 0 means it was not.

A healthy connection holds Tunnel Activity at 1, with traffic on the other two graphs whenever your resources talk to each other. A drop to 0 marks when the tunnel went down. If it is still down, Pause, restart, or delete a peering connection shows how to restart it, and Troubleshooting VPC covers what else to check.
