AWS EB Node.JS登录到CloudWatch

Question

是否有任何可能的解决方案将运行在Elastic Beanstalk上的应用程序的Node.JS日志流式传输到Amazon CloudWatch？

我确实看到了cwl-webrequest-metrics.config文件，但没有关于格式的信息我无法格式化它以将Node.JS日志（仅）传送到CloudWatch。

那你提前发表您的意见！

问题是有点老了，但对于那些你从谷歌的到来，这里是为Node.js的工作.ebextension配置日志洒进的CloudWatch：

# 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"}

      "/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}

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