Two important fields in Traefik are the "traefik.access.frontend_name" and "traefik.access.backend_name" fields. Based on these fields one can identify the service which is being hit, especially in a Docker world this is really useful to be able to visualize.
Currently fields defines these two as just being 'text', meaning one can't use these fields in visualizations within Kibana.
Could they please be changed to Keywords instead?
