How to use Package/Container Usage in ProGet/Otter

[geraldizo_0690]

Dear Supporters,

we are trying to get Package/Container Usage work.

Our Testenvironment in containers:

• ProGet 2025.24(Build 5)
• MSSQL
• Otter 2025.3 (Build 1)

The problem is, as soon as a server has been assigned into a role, for executing checkconfiguration with activated "Configuration drift:", the package/container scanner inside of ProGet will get the following error while scanning. And there is no information about package usage have been transfered from otter to proget.

Have any clue, why is this happening?

Scan using Otter at http://otter/ failed: Invalid name.

System.ArgumentException: Invalid name.

Hi @geraldizo_0690 ,

Thanks for trying out the feature! Unfortunately I think this feature broke around ProGet 2023 and no one seemed to notice it; we were actually planning on removing it in ProGet 2026.

We build the feature ages ago, but no one ever asked for it. It just "felt" like a "nice idea" at the time, but we never really thought out a proper use case. So was never documented very well and it would seem no one used it

Anyway... I'd be open to reviving it if we could actually figure out a use case. What are you trying to do? Would love to get an idea to see if we can solve a real-world problem here

Thanks,
Alex
