node.js - How to do Node online monitoring and error log analysis?

Question

I am doing front-end development. Recently I need to migrate an old system to Node.

There is no problem when I write the code, but I don’t know how to do the online monitoring solution and error log analysis?

Thanks.

Use pm2 to deploy the program, any standard output and standard error output will be written to the log file, errors are very convenient
