AWS EB Node.JS登录CloudWatch

Question

是否有任何可能的解决方案将在Elastic Beanstalk上运行的应用程序的Node.JS日志传输到Amazon CloudWatch？

我确实看到了cwl-webrequest-metrics.config文件但没有关于它的格式的信息我无法格式化它以将Node.JS日志(仅)传输到CloudWatch.

那你提前征求意见了!

问题有点老了，但对于那些来自 Google 的人来说，这里有一个用于 Node.JS 日志流式传输到 cloudwatch 的有效 .ebextension 配置：

# Store Node.JS Application Logs in Cloudwatch
Mappings:
  CWLogs:
    NodeJSLogGroup:
      LogFile: "/var/log/nodejs/nodejs.log"
      TimestampFormat: "%d/%b/%Y:%H:%M:%S %z"

Outputs:
  NodeJSCWLogGroup:
    Description: "Node.JS Application Logs"
    Value: { "Ref" : "AWSEBCloudWatchLogs8832c8d3f1a54c238a40e36f31ef55a0NodeJSLogGroup"}


Resources :

    Type: "AWS::Logs::LogGroup"
    DependsOn: AWSEBBeanstalkMetadata

          DefaultValue: {"Fn::Join":["-", [{ "Ref":"AWSEBEnvironmentName" }, "nodejs"]]}

  ## Register the files/log groups for monitoring

            "/tmp/cwlogs/conf.d/nodejs.conf":
              content : |
                [nodjs-log]
                file = `{"Fn::FindInMap":["CWLogs", "NodeJSLogGroup", "LogFile"]}`
                log_group_name = `{ "Ref" : "AWSEBCloudWatchLogs8832c8d3f1a54c238a40e36f31ef55a0NodeJSLogGroup" }`
                log_stream_name = {instance_id}
                datetime_format = `{"Fn::FindInMap":["CWLogs", "NodeJSLogGroup", "TimestampFormat"]}`
              mode  : "000400"
              owner : root
              group : root

看起来http://serebrov.github.io/html/2015-05-20-cloudwatch-setup.html也可能是一个很好的参考。
