[英]node.js - PM2 log uncaught exceptions to third-party service (as Logentries)
I'm using pm2 ( https://github.com/Unitech/pm2 ) in my node.js project. 我在我的node.js项目中使用pm2( https://github.com/Unitech/pm2 )。 Also I'm sending logs of errors of the app in Logentries ( https://logentries.com ).
此外,我在Logentries( https://logentries.com )发送应用程序错误日志。
I wonder is it possible to log uncaught exceptions from the app (when something fails badly and pm2 restarts the app for example)? 我想知道是否可以从应用程序中记录未捕获的异常(例如,当某些内容失败并且pm2重新启动应用程序时)? I know that using
process.on('uncaughtException')
is bad practice so would like to hear some suggestions. 我知道使用
process.on('uncaughtException')
是不好的做法,所以希望听到一些建议。
Thanks! 谢谢!
Where did you read that process.on('uncaughtException')
is a bad practice? 你在哪里读过那个
process.on('uncaughtException')
是一个不好的做法?
As long as you exit the process after logging the exception I don't see what's bad, here is an example: 只要在记录异常后退出进程,我就看不出有什么不好,这是一个例子:
process.on('uncaughtException', function(e) {
console.error('Ouch, an unhandled exception');
//I like using new Error() for my errors (1)
console.error(e instanceof Error ? e.message : e);
process.exit(1);
});

Edit pm2-interface is now deprecated, use require('pm2')
instead. 编辑 pm2-interface现已弃用,请改用use
require('pm2')
。 You will be able to do exactly the same as below by using bus system events . 通过使用总线系统事件,您将能够完成与下面完全相同的操作。
An alternative with pm2 is to use pm2-interface and listening to the process:exit
or process:exception
events: 使用pm2的替代方法是使用pm2接口并监听
process:exit
或process:exception
事件:
var ipm2 = require('pm2-interface')();
ipm2.on('ready', function() {
console.log('Connected to pm2');
ipm2.bus.on('process:exception', function(data){
console.log(data.pm2_env.name + 'had an exception');
});
});
This is really usefull when managing more than one process through a monitoring process. 当通过监视过程管理多个进程时,这非常有用。
