Issue/Introduction

Symptoms:

After upgrading, or restarting, the Skyline Collector virtual appliance, you are unable to reach the Skyline Collector user interface via a web browser.

Finally, the following message is displayed on the Skyline Collector virtual appliance console.

 

Environment

VMware Skyline Collector Appliance 2.x

Resolution

Please follow the steps in the workaround to resolve this issue until a permanent resolution can be provided.

Workaround:

Complete these steps to restore networking to the Skyline Collector virtual appliance.

1. Within the vSphere Client, open the console for the Skyline Collector virtual appliance virtual machine.

2. Log in to the Skyline Collector virtual appliance using the 'root' account.

3. First, restart the networkd service. Restarting the networkd service usually resolves this issue. Multiple restarts of the networkd service may be needed to resolve the issue.  Run the following command to restart the networkd service: systemctl restart systemd-networkd

4. Sometimes, restarting the networkd service results in a loss of network configuration. If this occurs, run the following command to reconfigure network details for the Skyline ColIector: /opt/vmware/share/vami/vami_config_net

Confirm that the Skyline Collector is available on the network. Try accessing the Skyline Collector user interface via the fully-qualified domain name (FQDN), or IP address within a web browser.

NOTE: The resolution is temporary, as any subsequent restarts of the Skyline Collector virtual appliance could cause the issue to occur again.
