      Setup InfluxDB to measure a wide variety of statistics like the time spent

        The UDP port to use for connecting to InfluxDB. InfluxDB requires that
        your server configuration specifies a database to store data in when
        sending messages to this port, without it metrics data will not be
        saved.

      = f.number_field :metrics_pool_size, class: 'form-control'
      .form-text.text-muted
        The amount of InfluxDB connections to open. Connections are opened
        lazily. Users using multi-threaded application servers should ensure
        enough connections are available (at minimum the amount of application
        server threads).

        The amount of seconds after which an InfluxDB connection will time
        out.

        A method call is only tracked when it takes longer to complete than
        the given amount of milliseconds.

      = f.number_field :metrics_sample_interval, class: 'form-control'
      .form-text.text-muted
        The sampling interval in seconds. Sampled data includes memory usage,
        retained Ruby objects, file descriptors and so on.
    .form-group
      = f.label :metrics_packet_size, 'Metrics per packet', class: 'label-light'
      = f.number_field :metrics_packet_size, class: 'form-control'
      .form-text.text-muted
        The amount of points to store in a single UDP packet. More points
        results in fewer but larger UDP packets being sent.
