Telegraf agent installation fails with "Install Failed" and "Bootstrap failed with Timeout, but no error messages found on VM" errors in UI

Products

• VMware Aria Suite

Issue/Introduction

• Installation fails with errors Install Failed and Bootstrap failed with Timeout, but no error messages found on VM.
• UI error: Bootstrap failed with Timeout, but no error messages found on VM.
• The /tmp/vmware-root_xxxx-xxxxxxxxxx/VMware-UCP_Bootstrap_Scriptsvmware10/uaf_bootstrap.log Log file error in Linux VM: bash: /tmp/vmware-root_xxxx-xxxxxxxxxx/VMware-UCP_Bootstrap_Scriptsvmware10/uaf-bootstrap.sh: Permission denied

Environment

Aria Operations 8.x

Cause

• Incorrect permission for /tmp directory (noexec) prevented execution of the bootstrap script.
• Windows Server 2025 is not supported with Telegraf agent.

Resolution

Verify the permission of /tmp directory:

• Use the findmnt -n -o OPTIONS /tmp or mount command to verify current permissions of the /tmp directory.

 

If /tmp has noexec permission then change /tmp permission from noexec to exec:

• Execute the mount -o remount,exec /tmp command to update or change /tmp permission from noexec to exec and use the findmnt command to verify the changes.

• The noexec permission is not listed which means the /tmp directory has exec permission.
• Restart the daemon service using systemctl daemon-reload command.
• If the service restart does not reflect the exec permission in /etc/fstab for /tmp then Reboot the VM for changes to take effect.

 

OR

 

• Backup the fstab file using cp /etc/fstab /etc/fstab.bak command and edit /etc/fstab and remove the noexec option and add exec for the /tmp mount point.
• Restart the daemon service using systemctl daemon-reload command.
• If the service restart does not reflect the exec permission in /etc/fstab for /tmp then Reboot the VM for changes to take effect.

 

Reinstall Telegraf agent:

• Remove older Telegraf instances from /tmp and /opt directories (if any) of the Linux VM where telegraf installation attempt was made.
• Reattempt installation from Install an Agent from the UI
