I also realized some Installation are missing. where is the list in the dashboard coming from?

[mogottsch]

I've added the our team label to the dashboard.

Concerning missing installations, I've identified the following:

• gauss
• cuckoo
• giraffe
• glippy
• gmc
• goat
• goose
• gopher
• goten
• icecream
• leopard

I traced the metrics back to the prometheus instances on the respective installations and could not find a reason why they are missing. I need to talk to someone with more knowledge to figure this out.

[mogottsch]

I talked to Antonia and we think the issue is not with our dashboard, but with the metrics themselves.
I will talk to Atlas about this.

Atlas identified the issues with the missing installations. Read the slack thread for more information.

Tldr: The reason for missing metrics varies across installations, but they have an issue tracking the problem of the customer ones (leopard & cuckoo).
