ruby 动态日志不会出现在AWS CloudWatch上

我正在尝试将AWS Cloud Watch与我的应用程序集成，但面临多个问题。我尝试了很多方法，但都没有成功。而且，我没有看到任何关于aws cloudwatch的好文档。如有任何帮助，我们将不胜感激

无法创建日志流
动态日志未显示

Gemfile

gem 'aws-sdk'
gem 'lograge'

config/initializers/cloudwatch_log.rb

begin
    @cloudwatch_client = Aws::CloudWatchLogs::Client.new

    # Define the log group and log stream names
    @log_group_name = ENV.fetch('APPLICATION_LOG_GROUP_NAME', '/home/app/insight')
    @log_stream_name = "#{Time.now.strftime('%Y-%m-%d')}/$[LATEST]/#{Time.now.to_i}"
    Rails.logger.info "log_group_name: #{@log_group_name} and log_stream_name: #{@log_stream_name} in #{Rails.env} environment...!!!"
    
    @cloudwatch_client.create_log_stream({
        log_group_name: @log_group_name,
        log_stream_name: @log_stream_name
    })

    Rails.application.config.logger.extend(ActiveSupport::Logger.broadcast(Logger.new($stdout)))

    Rails.application.config.logger.extend(ActiveSupport::Logger.broadcast(@cloudwatch_client))
rescue Aws::Errors::MissingRegionError, Aws::Sigv4::Errors::MissingCredentialsError => e
    Rails.logger.info "be_admin: AWS credentials not found for CloudWatchLog...!!!"
end

production.rb

require "active_support/core_ext/integer/time"

Rails.application.configure do
  config.cache_classes = true

  config.eager_load = true

  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  config.public_file_server.enabled = true

  config.assets.compile = false

  config.flipper.preload = false

  config.active_storage.service = :local

  config.action_mailer.perform_caching = false

  config.active_support.report_deprecations = true

  logger           = ActiveSupport::Logger.new($stdout)
  logger.formatter = config.log_formatter
  config.logger = ActiveSupport::TaggedLogging.new(logger)

  # Set log level from LOG_LEVEL
  default_log_level = Rails.env.development? ? :debug : :info
  config_log_level  = ENV.fetch("LOG_LEVEL", default_log_level).to_s.downcase.to_sym
  config.log_level = if %i[debug info warn error fatal].include?(config_log_level)
                       config_log_level
                     else
                       default_log_level
                     end

  config.lograge.enabled = !Rails.env.development?

  config.lograge.formatter = Lograge::Formatters::Raw.new

  config.logger = Logger.new($stdout).tap do |logger|
    logger.formatter = config.log_formatter
    config.logger    = ActiveSupport::TaggedLogging.new(logger)
  end

  config.active_record.dump_schema_after_migration = false
end

如果我添加这一行，它将创建一个日志流，但仍然没有动态日志

@cloudwatch_client.put_log_events({log_group_name: @log_group_name, log_stream_name: @log_stream_name, log_events: [{timestamp: Time.now.to_i * 1000, message: "logger initialted"}]})

对于那些努力将AWS cloudwatch与Rails应用程序集成的人来说。下面是解决方案
Gemfile

gem 'aws-sdk'

在库cloudwatch_logger. rb中创建一个文件。我们试图用云监视记录器覆盖Logger类，以便发送动态日志

require 'aws-sdk-cloudwatchlogs'
class CloudwatchLogger < Logger
  def initialize(log_group_name, log_stream_name)
    super(STDOUT)
    @log_group_name = log_group_name
    @log_stream_name = log_stream_name
    @cloudwatch_logs = Aws::CloudWatchLogs::Client.new
    create_log_stream_if_not_exists
  end

  def add(severity, message = nil, progname = nil, &block)
    severity ||= UNKNOWN
    message ||= (block && block.call) || progname
    return true if severity < level

    message = format_message(severity, Time.now, progname, message)
    super(severity, message)

    @cloudwatch_logs.put_log_events(
      log_group_name: @log_group_name,
      log_stream_name: @log_stream_name,
      log_events: [
        {
          timestamp: Time.now.to_i * 1000,
          message: message
        }
      ]
    )
    true
  end

  def format_message(severity, timestamp, progname, message)
    "#{timestamp} #{severity} -- #{progname}: #{message}\n"
  end

  def create_log_stream_if_not_exists
    begin
      @cloudwatch_logs.create_log_stream(
        log_group_name: @log_group_name,
        log_stream_name: @log_stream_name
      )
    rescue Aws::CloudWatchLogs::Errors::ResourceNotFoundException => e
      puts "Error creating log stream: #{e.message}"
    end
  end
end

最后，从初始化器文件夹中调用该类。另外，将www.example.com绑定CloudwatchLogger.new到try catch中，就像使用docker一样，这样它就无法在docker构建时找到区域cloudwatch_logger.rb

require 'cloudwatch_logger'

log_group_name =  'enter_your_log_group_name'
log_stream_name = "#{Time.now.strftime('%Y-%m-%d')}/$[LATEST]/#{Time.now.to_i}"
begin
  Rails.logger = CloudwatchLogger.new(log_group_name, log_stream_name)
rescue Aws::Errors::MissingRegionError => e
  puts "Error fetching at region: #{e.message}"
end
