Issue/Introduction

• When attempting to install the Telegraf agent on a virtual machine (VM) from the VMware Aria Operations 8.X UI, the installation fails at stage 1 with the following error message:

                  Bootstrap failed for VM <VM-ID> at stage 1 with error message Failed to download: https://FQDN-Cloudproxy/downloads/salt/config-utils.bat  

• The log file (uaf_bootstrap.log) provides additional details, indicating that the ARC server is unreachable from the endpoint VM.

Environment

VMware Aria Operations: 8.X

Cause

The issue occurs because the endpoint VM is unable to resolve or reach the Application Remote Collector (ARC) server due to proxy settings configured in the default web browser. These settings interfere with the Telegraf agent installation process by preventing the necessary files from being downloaded.

Resolution

To resolve the issue, follow these steps:

1. Verify Network Connectivity:

• Ensure all required ports are open on the endpoint VM.
• Verify the network connection between the endpoint VM and the cloud proxy VM.

2. Check and Remove Proxy Settings:

• Open the default web browser on the endpoint VM.
• Navigate to the proxy settings and remove any configured proxy.

3. Retry accessing the URL:

• Open the URL https://FQDN-Cloudproxy/downloads/salt/config-utils.bat in the browser to confirm it is accessible.

4. Re-run the Installation Process:

• Restart the Telegraf agent installation from the VMware Aria Operations UI.
