  ## MySQL Prometheus exporter containers' resource requests and limits
  ## ref: https://kubernetes.io/docs/user-guide/compute-resources/
  ## We usually recommend not to specify default resources and to leave this as a conscious
  ## choice for the user. This also increases chances charts run on environments with little
  ## resources, such as Minikube. If you do want to specify resources, uncomment the following
  ## lines, adjust them as necessary, and remove the curly braces after 'resources:'.
  ## @param metrics.resources.limits The resources limits for the container
  ## @param metrics.resources.requests The requested resources for the container
  ##
  resources:
    ## Example:
    ## limits:
    ##    cpu: 0.5
    ##    memory: 256Mi
    limits:
      cpu: 50m
      memory: 50Mi
    ## Examples:
    ## requests:
    ##    cpu: 0.5
    ##    memory: 256Mi
    requests:
      cpu: 50m
      memory: 50Mi

  ## Prometheus Operator ServiceMonitor configuration

    jobLabel: ""
    ## @param metrics.serviceMonitor.interval How frequently to scrape metrics (use by default, falling back to Prometheus' default)
    ## ref: https://github.com/coreos/prometheus-operator/blob/master/Documentation/api.md#endpoint

  ## Prometheus Operator PrometheusRule configuration
  ##
  prometheusRules:

    ## If using the [Helm Chart](https://github.com/helm/charts/tree/master/stable/prometheus-operator) this is the name of the Helm release and 'app: prometheus-operator'
