Node.JS - forever vs upstart+monit?

Question

Highload

Good evening everyone!

First, a little introductory part - there is an application - express + socket.IO (yes, like everyone else :). There is haproxy as a reverse proxy. The application scales across n servers. On each server cluster is used. So actually the question is: what is preferable to use for the "eternal" operation of the node? Of the advantages of forever, I see only a very simple use - 1 command and it's done. upstart + monit - more difficult (slightly) configurable + monit collects statistics about the state of the operating system, that's all. Which of these performs best in production? Can anyone share some tricks? I'm afraid for forever - it's also essentially a node server, can't it happen that it hangs for the company with the main server in case of mega-popularity?

If someone considers himself a node specialist or just has something to say - please hit the PM, there are a whole bunch of questions, you don’t want to pull stackoverflow or habra for the sake of every little thing =)

Thanks in advance to everyone!

Answer 1

I used supervisord.org for a couple of years , it worked without problems, and, in principle, a well-known thing for securing anything from falls.

Answer 2

There was already a similar question, I suggested there:

Runit (but this is an analogue of supervisord), it’s very easy to launch in one line, it can keep a log, run processes from the user, in case of a process crash, raise it, replace init.d scripts. As far as I remember, it is written in C and eats a minimum of resources.

Answer 3

pm2 - for sale it's the best, from the pros - simplicity, load balancer for web applications (express based), built-in monitoring with an excellent API.
