单独的信息和错误日志Bunyan [英] Separate info and error logs bunyan

问题描述

正如我在博客中看到的许多日志一样，我发现Bunyan适合记录日志，但是存在一个问题，即它无法根据其级别记录到文件中.

As I have seen many logs in blogs and I find bunyan suitable for logging but there is problem with it that it can't log to file according to their level.

下面是我要遵循的代码结构

Below is code structure I am following

const RotatingFileStream = require('bunyan-rotating-file-stream');
const bunyan = require('bunyan');

    var log = bunyan.createLogger({
          name: 'ShotPitch',


          streams: [{
            name: 'info',
            level: 'info',
            stream: new RotatingFileStream({
              path: 'info.%d-%b-%y.log',
              period: '1d', // daily rotation
              totalFiles: 10, // keep 10 back copies
              rotateExisting: true, // Give ourselves a clean file when we start up, based on period
              threshold: '10m', // Rotate log files larger than 10 megabytes
              totalSize: '20m', // Don't keep more than 20mb of archived log files
              gzip: true // Compress the archive log files to save space
            })
          }, {
            name: 'error',
            level: 'error',
            stream: new RotatingFileStream({
              path: 'error.%d-%b-%y.log',
              period: '1d', // daily rotation
              totalFiles: 10, // keep 10 back copies
              rotateExisting: true, // Give ourselves a clean file when we start up, based on period
              threshold: '10m', // Rotate log files larger than 10 megabytes
              totalSize: '20m', // Don't keep more than 20mb of archived log files
              gzip: true // Compress the archive log files to save space
            })
          }] 
        });

 log.info('Hello World');
 log.error('Hello World error log');

o/p:info.log:

o/p: info.log :

{"name":"ShotPitch"，"pid":7621，"level":30，"msg":"Hello World"，"time":"2017-09-03T18:29:04.181Z"， "v":0}

{"name":"ShotPitch", "pid":7621,"level":30,"msg":"Hello World","time":"2017-09-03T18:29:04.181Z","v":0}

{"name":"ShotPitch"，"pid":7621，"level":50，"msg":"Hello World"，"time":"2017-09-03T18:29:04.181Z"， "v":0}

{"name":"ShotPitch", "pid":7621,"level":50,"msg":"Hello World","time":"2017-09-03T18:29:04.181Z","v":0}

o/p:error.log:

o/p: error.log :

{"name":"ShotPitch"，"pid":7621，"level":50，"msg":"Hello World"，"time":"2017-09-03T18:29:04.181Z"， "v":0}

{"name":"ShotPitch", "pid":7621,"level":50,"msg":"Hello World","time":"2017-09-03T18:29:04.181Z","v":0}

结论:

info.log同时显示信息和错误日志

info.log shows both info and error logs

error.log仅显示错误日志

error.log shows only error logs

我只希望信息日志记录在info.log中，但无法执行.有没有人可以帮助您?另外，如果告诉我如何更改为级别:信息"而不是级别:30

I want info logs only in info.log but unable to do. Is there anyone that can help ?. Also if tell me how to change to level: "info" rather than level:30

推荐答案

我遇到了同样的问题，最后我创建了两个变量，如:

I met the same problem, finally I created 2 variables like:

var debugLog = bunyan.createLogger({
  name: 'general',
  streams: [
    {
      level: 'debug',
      path: './debug.log'
    }]
});

var errLog = bunyan.createLogger({
  name: 'general',
  streams: [
    {
      level: 'error',
      path: './error.log'
    }]
});

debugLog.info('hello world');
errLog.error('error');

然后，日志将位于不同的日志文件中.

Then logs will be in different log files.
