prometheus output plugin not working for multi worker scenario

[Nikunj-Sharma]

Hi there,

Thanks for this wonderful plugin. I am trying to get "The total number of outgoing records" in case of multi worker scenario. But it seems like prometheus output plugin doesn't support multiple worker.

Below is the match and system configuration I used(4 workers)

<system>
  workers 2
  root_dir /Users/snikunj/Desktop/td-agent/buffer
</system>
<match debug.**>
  @type copy

  <store>
    @type prometheus
    # @id out_prometheus
    <metric>
      name fluentd_output_status_num_records_total
      type counter
      desc The total number of outgoing records
      <labels>
        tag ${tag}
        hostname ${hostname}
      </labels>
    </metric>
  </store>
</match>  

Below is the error I am getting

[error]: config error file="/etc/td-agent/td-agent.conf" error_class=Fluent::ConfigError error="Plugin 'prometheus' does not support multi workers configuration (Fluent::Plugin::PrometheusOutput)"

Is there any way I can achieve my requirement? getting "The total number of outgoing records" in case of multi worker?

Please update to v1.4.0 which supports multi worker.
