Activating DORA Metrics in Self-Hosted GitLab 16.6

Hello Community,

I hope someone can help me. I would like to activate the DORA Metrics in my self hosted GitLab, but it does not work so far, although I have already activated the flag “dora_performers_score_panel”.
I am currently using GitLab 16.6 (self-hosted). Also the menu item “Analytics” under Settings → General, could not be found in my self-hosted GitLab.
Can any of you help me? I don’t know what else I need to set.
Thank you all for your help.

Best regards
