    ## Prefix used to register routes, overriding externalUrl route.
    ## Useful for proxies that rewrite URLs.
    ##
    # Following was set in an attempt to serve Prometheus from "/prometheus",
    # which would allow Prometheus to run from `monitoring-service-gateway.yaml`.
    # Unfortunately, the static resources were still served from /
    # So I commented it out.  Till this is resolved, run Prometheus from
    # its own LoadBalanced Service, `prom-ingress`.

    additionalScrapeConfigs:
      # Below copied from https://github.com/helm/charts/blob/master/stable/prometheus/values.yaml
      # Example scrape config for pods
      #
      # The relabeling allows the actual pod scrape endpoint to be configured via the
      # following annotations:
      #
      # * `prometheus.io/scrape`: Only scrape pods that have a value of `true`
      # * `prometheus.io/path`: If the metrics path is not `/metrics` override this.
      # * `prometheus.io/port`: Scrape the pod on the indicated port instead of the default of `9102`.
