I get an error message:

on Terminal the same:

Everything is set up in Zammad Backend:

Did I missed something in the documentary or while setting up Grafana ?
I used Grafana as docker container but it looks like an error on the elasticsearch site.

Do I have to grant more permissions ?

Ensure you’re using the provided instance names from within the integration page.
It’s not the same the documentation(s) suggest as they’re instance specific.

Hi and thanks for the supply, I had to add an asterisk to the Index Name:

Wrong:
zammad_production_chat_session

Right:
*_production_chat_session

And now the Dashboard is shining.
