Troubleshooting - Diagnostic Results

This page explains the major items to examine while doing a Run diagnostics on a gateway.

You can run Diagnostics in the Controller from Troubleshoot > Diagnostics > Gateway > Diagnostics.

  1. Select a gateway to run diagnostics and click Run.

  2. When it finishes, click Show to display on the console.

  3. Click Submit to send the diagnostics results to the Aviatrix support team.

The diagnostics test if the gateway is reachable and if its services are up and running.

            ]
        },
        "service": "Up"
    },

Indicates Controller status. The SSH service port 22 status "Down" is expected as you are not allowed to connect the ssh port to the Controller or gateways.

Gateway Output

"SSH": {
    "port": {
        "22": [
            "up",
            "reachable"

        ]
    },
    "service": "Up"
},
"Upload": "Pass",

  • Indicates Gateway port 22 and 443 status.

  • Expected value: Up and reachable. If not, please make sure the gateway has its security group port 22 & 443 open to the Controller’s EIP in AWS console.

  • It’s expected that SSH port 22 is reachable as the Controller will use the port to do diagnostics on the Gateway.

  • Make sure HTTPS port 443 is reachable in this section since it indicates that the Controller is able to reach the Gateway for configuration and software package delivery.

Upload Output

"Upload": "Pass",

  • Indicates that Aviatrix Controller is able to upload files to the gateway.

  • Expected value: Pass

  • If it fails, please check that port 443 is open in both security group and VPC ACL between the Controller and the gateway instance in the AWS console.

HTTPS GET

"HTTPS GET": "Pass",

  • Indicates connectivity for HTTPS request from gateway to the controller.

  • Expected value: Pass if GW can communicate with Controller without issue.

  • When It shows “Fail” please check both Controller and Gateway security group. You can also check if the Controller has its security group port 443 open to the gateway’s EIP in the AWS console.
