正如我在博客中看到许多日志,我发现bunyan适合于日志记录,但有问题,它无法根据它们的级别登录到文件。单独的信息和错误日志bunyan
下面是我下面
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码结构:info.log建立:
{ “名称”: “ShotPitch”, “PID”:7621, “电平”: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。日志:
{“name”:“ShotPitch”,“pid”:7621,“level”:50,“msg”:“Hello World”,“time”:“2017-09-03T18:29:04.181Z” , “v”:0}
结论:
info.log建立同时显示信息和错误日志
error.log中只显示错误日志
我想信息记录只在info.log建立但无法做到。有没有人可以帮忙?另外,如果告诉我如何更改级别:“info”而不是级别:30
我不能为单独的日志记录制作单独的实例。如果可能的话,单个实例对我来说可以。此外,如果级别设置为信息的字符串,错误,那么读取日志将更加可行。 – Creator
您只能设置严重级别。在这里查看严重性级别https://github.com/trentm/node-bunyan#levels –
