telegraf telemetry can't get metrics microburst

[bienkma]

I had a telegraf with telemetry gRPC port. It did not collect microburst metric. My configuration is below:

[global_tags]
[agent]
  interval = "10s"
  round_interval = true
  metric_batch_size = 1000
  metric_buffer_limit = 10000
  collection_jitter = "0s"
  flush_interval = "10s"
  flush_jitter = "0s"
  precision = "0s"
  hostname = ""
  omit_hostname = false
[[outputs.influxdb_v2]]
   urls = ["http://127.0.0.1:8086"]
   token = "token"
   organization = "ghtk"
   bucket = "ghtk"

[[outputs.file]]
  ## Files to write to, "stdout" is a specially handled file.
  files = ["/tmp/metrics.out"]

  data_format = "influx"

• and input

[[inputs.cisco_telemetry_mdt]]
 transport = "grpc"
 service_address = ":4317"
 max_msg_size = 20000000
