| `prometheus.metricServer.serviceMonitor.port` | string | `"metrics"` | Name of the service port this endpoint refers to. Mutually exclusive with targetPort |

, this variable is used to set endpoint’s name of service monitor, but due to incorrect value reference in

, it references .Values.prometheus.metricServer.portName which is used for set port name of metric server.
