PM2监控vs PM2日志

Question

What's the difference between these commands? I couldn't find a clear explanation on which should be used at what scenarios.

Answer 1

pm2 monit is about process management:

The local monitoring tool get you insight about CPU usage, memory usage, loop delay or request/min for each process

pm2 logs is about log management and shows you the saved logs of all apps or a specific app - you won't see any details about the current CPU usage, memory usage and so on.

In my understanding pm2 monit provides a ad hoc view about the current processes including their logs in real time, while pm2 logs provides a retrospective view through saved logs (though they are also available at realtime).
