Only 3 of 5 workers are running

[Beheer]

Hello,
I just took over our Veeam in Azure config from an external party and need to solve some issues. New to VBA, used to B&R so far.
We use the latest VBA release.
We have 5 workers configured, all the same VM type, min instances 0, max instances 5.
Yesterday I solved the issue that our big fileserver was not backed up anymore for a while, pointed out to be a worker memory issue.
So I changed the default profile size from Standard_D2as_v5 to Standard_F8s_v2 (by Veeam recommendation for VMs over 1 TB in size.
I will start configuring with Advanced configuration to use different worker sizes for Small, Medium and Large. But first everything should work smooth like I was used to with B&R on-prem.
The fileserver backup ran succesful last night and much quicker than in the last months when it wass still running.

Now a backup policy that backups most of our Azure VMs (50) seems to take longer.
In the last month it ran for 10 hours, now it has been running for 11 hours with only 16 of the 50 VMs processed, the rest is waiting for available worker.
I notice that only 3 of the maximum of 5 configured workers is active.
I have no idea if this is because of my change since I have only started intensive monitoring yesterday and don't know how to figure out from the big log zip that can be downloaded where to find how many workers where used the last few months.

Can anyone tell me why only three workers are active?
Kind regards,
Han

Found what the issue was, the amount of vCPUs in the specific Azure subscription were consumed.
