I don't know how we should handle that. Rewrite a whole part of the frontend part seems not to be the best idea since we want to avoid to handle too many modifications for only one feature. I'll open a new PR to add micrometer with a default registry dependency. WDYT @joewhite101 @danielpetisme ? |

Maybe, we should wait. There is a chance that this kind of admin pages will no longer to the generator itself -> jhipster/generator-jhipster#12090 We should suggest modifications to JHCC directly, WDYT? |
