Ubuntu – Where do log files locate in pm2 in sudo mode

I’m new to PM2 and ubuntu-related issues.

I’m running an app using sudo with the syntax sudo pm2 start app.js --time.

However, when I tried to check the files in $HOME/.pm2/logs/app-error.log, I couldn’t find any logs related to what I logged in the code. I believe sudo pm2 start is different from pm2 start, and the log files are only for the pm2 start.

My question is, how can I check the logs in sudo pm2?

    By default, pm2 will store log files in ~/.pm2/logs.

    If you execute pm2 as the root user, the logs will be stored in /root/.pm2/logs/.

    sudo executes commands as the root user, and that also entails that the home directory (referred to as $HOME or ~) that the command sees is the root user’s home directory, which usually is /root.

    So, if a program writes logs to the user’s home directory, the location of the log files will depend on what user is executing that program.

    You can change the logs location like this:

    Generate an ecosystem file:

    pm2 ecosystem simple

    Then edit the ecosystem file and add lines for changing the default location:

    module.exports = {
  apps : [{
    name   : "My Application",
    script : "./myapp.js",
    error_file : "/var/log/pm2/myapp/err.log",
    out_file : "/var/log/pm2/myapp/out.log"
  }]
}

    Alternatively, you can also use the command line:

    pm2 start -n "My application" -o /var/log/pm2/myapp/out.log -e /var/log/pm2/myapp/err.log /path/to/my/application

    I believe it’s in /root/.pm2/logs/. Probably you haven’t check them all using ls -a
