Deploying cloud proxy with Log Forwarding toggled on displays a blank key

Products

• VMware Aria Suite

Issue/Introduction

In Aria Operations when adding a new cloud proxy the registration key displays a blank key when toggling the Log Forwarding on.

Environment

Aria Operations 8.x

Cause

The custom certificate on Aria Operations is large.  When deploying a cloud proxy with Log Forwarding toggled on it uses the certificate to generate the key which is too big to display and instead generates a blank key.  The vCenter will also not accept the key if it is too large with "Invalid value" message.

Resolution

To workaround the issue generate a new key using the attached lf-gen-otk.py script:

1. Upload the lf-gen-otk.py script to the primary node to /tmp.
2. From Aria Operations deploy a new cloud proxy with Log Forwarding toggled on.  The registration key will go blank.
3. From the vSphere client deploy the cloud proxy OVF and follow the prompts until you get to the Unique Registration Key prompt.
4. SSH into the primary node as root and run the following:
   1. cd /tmp
   2. python lf-gen-otk.py
5. Copy the generated key output from the script and paste it into the Unique Registration Key prompt.
6. Click Finish to complete the install.
