the prometheus plugin config of fluentd is like below

  prometheus.conf: |-
    <source>
      @type prometheus
      port 24231
      metrics_path /prometheus
      aggregated_metrics_path /metrics
    </source>

  metrics.conf: |-
    <source>
      @type prometheus_monitor
    </source>
    <source>
      @type prometheus_output_monitor
    </source>

when I call fluentd reload by http://127.0.0.1:24444/api/config.gracefulReload, the log of fluentd output like below:
