You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: environment_logger.rb
    path of file: ./repos/dd-trace-rb/lib/datadog/tracing/diagnostics
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'date'
require 'json'
require 'rbc
    
        def self.collect_and_log!(responses: nil)
          log_once! do
            env_data = EnvironmentCollector.collect_config!
            log_configuration!('TRACING', env_data.to_json)

            if responses
              err_data = EnvironmentCollector.collect_errors!(responses)
              err_data.reject! { |_, v| v.nil? } # Remove empty values from hash output
              log_error!('TRACING', 'Agent Error', err_data.to_json) unless err_data.empty?
            end
          end
