Example 4: Creating a VPN Connection Monitor

Scenario

This section describes how to create a VPN connection monitor by calling APIs.

Prerequisites

• You have created a VPN connection. For details, see Creating a VPN Connection.

• You have obtained a user token if you need to use token authentication. In addition, you need to add X-Auth-Token to the request header when calling an API. For details about token authentication, see Authentication.
  

  The token obtained through IAM is valid for only 24 hours. When using a token for authentication, cache it to avoid frequent calling.

Data Preparation

Procedure

1. Create a VPN connection monitor.
   1. Send POST https://{endpoint}/v5/{project_id}/connection-monitors.
   2. Add X-Auth-Token to the request header.
   3. Specify the following parameters in the request body:

      {
          "connection_monitor": {
              "vpn_connection_id": "cae286f2-demo-a8df-va86-e22416ca1220"
          }
      }

   4. Check the response.
      • The request is successful if the following response is displayed. In the response, id indicates the ID of a VPN connection monitor.

        {
            "connection_monitor": {
                "id": "76f64229-demo-a8df-va86-3907e2815b6d",
                "vpn_connection_id": "cae286f2-demo-a8df-va86-e22416ca1220",
                "type": "gateway",
                "source_ip": "88.***.***.60",
                "destination_ip": "192.***.***.0",
                "proto_type": "icmp"
            },
            "request_id": "54af23d8-989e-445d-bb48-0a9da33d7f0f"
        }

2. Query details about the VPN connection monitor.
   1. Send GET https://{endpoint}/v5/{project_id}/connection-monitors/{connection_monitor_id}.
   2. Add X-Auth-Token to the request header.
   3. Check the response.
      • The request is successful if the following response is displayed. In the response, id indicates the ID of a VPN connection monitor.

        {
            "connection_monitor": {
                "id": "76f64229-demo-a8df-va86-3907e2815b6d",
                "status": "ACTIVE",
                "vpn_connection_id": "cae286f2-demo-a8df-va86-e22416ca1220",
                "type": "gateway",
                "source_ip": "88.***.***.60",
                "destination_ip": "192.***.***.0",
                "proto_type": "icmp"
            },
            "request_id": "72d05395-0637-4f93-9844-b4979e9d7bdc"
