Environment

Aria Operations 8.18.x

Cause

File permissions were changed to the root user on Cloud Proxy under the directory /ucp/downloads/salt.
This incorrect permission setting led to the Python environment not being able to locate necessary modules like psutil and yaml.

Resolution

To be able install telegraf agents on Linux based VMs:
  1. Verify the ownership of the folders under the directory /ucp/downloads/salt in cloud proxy. The ownership must be admin/admin. If the ownership is not admin, reset permissions/ownership.
  2. Run the /ucp/ucp-config-scripts/ucp-firstboot.sh script and verify the permissions of the folder.
  3. Re-install the agent after successful execution of the script.
