Problem about akka to New Relic integration

I am trying to see akka metric on New Relic with using Lightbend Cinnamon Library.

Until this time, i can not see any metrics on new relic.

When i check new relic agent logs, i see the logs below;

2021-04-20T07:13:30,690+0000 [71585 67] com.newrelic WARN: Dropped 191 custom events out of 1,024.
2021-04-20T07:15:30,690+0000 [71585 67] com.newrelic WARN: Dropped 323 custom events out of 1,156.
2021-04-20T07:17:30,683+0000 [71585 67] com.newrelic WARN: Dropped 499 custom events out of 1,332.
2021-04-20T07:19:30,680+0000 [71585 67] com.newrelic WARN: Dropped 631 custom events out of 1,464.

My cinnamon config is illstrated below;



cinnamon {
  host = "dispatch-cinnamon"
  application = "dispatch-cinnamon-app"
}

cinnamon{
  akka {
      cluster {
         shard-region-info = on

         node-metrics = on
      }
      remote{
          serialization-timing = on
          failure-detector-metrics = on
      }
      actors {
        "/user/*" {
          # WARNING: In a real application, it will be better to tag the actors
          # so that will be easier to make sense of the metrics. But since this is
          # just a sample, we are using `instance` to keep it simple.
          # See the following page for more information:
          # https://developer.lightbend.com/docs/telemetry/current/instrumentations/akka/actors-typed.html
          report-by = instance
          }

      conversion-time-unit = "ms"

      # Group by category instead of name.
      # If enabled the New Relic event names will only include the metric category and not the name,
      # and a new tag named "metric" containing the metric name will be added.
      # E.g. the metric "lightbend:actors:mailbox_size" will be reported as "lightbend:actors" with
      # the tag "metric" -> "mailbox_size"

i can not find any solution. can u help me?. thx a lot
