🐛 BUG: Logs get aggregated in PM2.log in cluster mode #5633

What's going wrong?

So I have multiple apps that by default have their own log files in the default folder. They are used in fork mode as they should. Now, when I turn them into cluster mode. They start in their previous log files but then all stdout from the running apps only land in the main pm2.log which is very confusing. So the daemon takes it all.

How could we reproduce this issue?

  1. https://jonascodeblog.vercel.app/blog/nx-pm2-plugin follow those steps
  2. then add "instances": 1 to the pm2 target config options.

It doesn't matter if you use the plugin or not, I also tried a config file and it shows the same result. Logs work correctly in fork mode but in cluster mode the start up is logged in the log file and after that everything is piped to PM2 log.

I also tried different names and even namespaces but nothing helps. pm2 log something will never show the app name or namespace for the clustered apps
