@almoelda Any particular reason to have this in the gitops-engine and not as a health customization lua script in argo?

For health extensions, i feel like Lua is much simpler and flexible if changes are required: https://argo-cd.readthedocs.io/en/stable/operator-manual/health/#way-2-contribute-a-custom-health-check

@agaudreault You're right. I'll make the changes.
