How to run node.js process with forever and logging?

问题

I see here http://socket.io/docs/logging-and-debugging/ that if I want to run logs, I do like this:

DEBUG=* node yourfile.js

this works.

But I want to also run process with forever.

https://www.npmjs.com/package/forever

But now actually I do not even know if I need forever. Then intention of running forever was - if server dies - forever restarts it.

But the problem is that server dies, clients cannot connect and forever does not restart it. Then node process is using socket.io.

So as I understand - process is not dead, but there is something wrong inside the process - with socket.io.

After we restart node server file, it is working again, for about 2 weeks.

As far as I remember - I need forever to run node process in the background. Otherwise process will be stopped when I close terminal.

How do I run command

DEBUG=* node yourfile.js

with forever so it would log output to files?

I tried like this

$ forever -c 'DEBUG=* node' server.js

but it did not work.

Also tried like this:

forever -o out.log -e err.log my-script.js

But also did not work, it looks different.

Running like this:

forever -o out.log -e err.log start my-script.js

starts proccess, but when I run

forever logs

I do not see any logs, so its no the same.

DEBUG=* node yourfile.js

floods many logs instantly. I am not sure if I want that much logs, but I have no idea how to solve disconnection problem.

Update

Based on comments I tried like this:

DEBUG=* forever start server.js > node.log

node.log file was created, but it just has 3 lines, which means it is not the same log as is when I run

DEBUG=* node server.js

This is what the logs look like which I want to see in text files.

socket.io:server initializing namespace / +0ms
  socket.io:server creating engine.io instance with opts {"path":"/socket.io"} +                                                                                            5ms
  socket.io:server attaching client serving req handler +3ms
