Are you refering to the AMD Status report for Capacity Status? You may want to edit the connection from the RUM Console Device list and ensure the check comes back complete (esp the Guided configuration).
If I remember right - you had sym links to the dynatrace volume in the AMD. You may need to update the permissions on the parent directory so the processes can access the sub-directories.
Yes I am referring to the AMD Capacity Status. I only upgraded 1 of of the AMDs, and I did not update the CAS or ADS, and that is the AMD I have lost the status on, the other 2 AMDs still show data. When I edit the connections, all connections come back complete. If all the connections comes back checked, can it still be a permissions issue?
On a Side note, I upgraded all my devices in the Non-Prod env (CAS, ADS and 1 AMD) to 12.3.8 and I have also lost AMD Capacity Status information, so I do not think it is version mismatch issue.
This issue was resolved. It was due to a permissions and ownership issue on the sym link on the AMD. After applying the update, the ownership is changed back to root:root. I changed the ownership and right, and the AMD Status reports are back to normal. Thank you all for the advice.
