Make pm2 log to console

Question

I am running a node webserver using pm2. Since pm2 spawns another process and redirects stdout and stderr to files, I have to look somewhere else for the logs. Ideally, I would like to have the node process output to the same console window that I've run pm2 from. Otherwise, I would settle for pm2 run the node process with an active console window and have stdout and stderr of the node process write to that console window. How can this be achieved? I'm on a windows machine.

Answer 1

我相信您还可以看到由命令 pm2 pm2 logs或pm2 logs [app-name]守护运行的进程的stdout和stderr 。

Answer 2

Found the answer (their documentation is not that great), just added the --no-daemon flag, seems to have done it. Although, it appears that it's still logging to the file (even when using the flag) on the first uptime. Once the process gets restarted (I'm watching for file changes) it starts logging out to the console

Answer 3

you can easily achieve that by starting another terminal/console and run this command

 pm2 log

logs everything to the terminal except console.log

 pm2 logs

logs everything to the terminal and console.log

Answer 4

programmatically you can do something like this:

const pm2 = require('pm2')

pm2.connect(function(err) {
  if (err) {
    console.error(err);
    process.exit(2);
  }
  pm2.start([
    {
      script             : "server.js",
      output: "/dev/stdout",
      error: "/dev/stderr",
    },
  ]
    , function(err, proc) {
      if(err) {
        throw err
      }
    });
})
