## If you need to specify a time field in the log as the timestamp, you can configure the following time parsing settings:
filter {
  date {
    match => ["produce_log_time","yyyy-MM-dd HH:mm:ss.SSS"]
    target => "@timestamp"
  }
}

output {
  cls{
     endpoint  => "[CLS data access domain name]"
     topic_id  => "[Log topic ID]"
     access_key_id     => ""
     access_key_secret => ""
  }
}
