正如我在博客中看到的许多日志,我发现 bunyan 适合进行日志记录,但它存在无法根据其级别记录到文件的问题。
下面是我正在关注的代码结构
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:
{"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}
o/p:error.log:
{"name":"ShotPitch", "pid":7621,"level":50,"msg":"Hello World","time":"2017-09-03T18:29:04.181Z","v" :0}
结论:
info.log 显示信息和错误日志
error.log 仅显示错误日志
我只希望 info.log 中的信息日志但无法做到。有没有人可以帮助?另外,如果告诉我如何更改为级别:“信息”而不是级别:30
