I'm using PM2 for clustering. It worked just fine when using NodeJS 0.10.31 and PM2 0.12.14. I upgraded NodeJS to 0.12.4 and PM2 to 0.12.16 and now when launching the following command :
pm2 start app.js -i 5
I get :
[PM2] Spawning PM2 daemon
[PM2] PM2 Successfully daemonized
[PM2] Process app.js launched
│ app │ 0 │ cluster │ 1372 │ online │ 0 │ 0s │ 30.500 MB │ disabled │
I expected 5 clusters but I get only one (one row in the table). I didn't see anything in the logs so far. Any idea ?

Running Multiple PM2 If you want to run multiple PM2 under the same user, you can override the variable PM2_HOME . Setting the PM2_HOME will change the PM2 configuration folder, like communication sockets ( $HOME/. pm2/pub. sock and $HOME/.
PM2 is a Production Process Manager for Node. js applications with a built-in Load Balancer. When properly configured, PM2 will automatically run your app in cluster mode, spawn workers for you, and take care of spawning new workers when a worker dies.
PM2 is an open-source distributed multithreaded programming environment designed to support efficiently distributed programs with a highly irregular behavior (e.g. branch and bound search, computation on sparse matrices, etc.)
If you've previously run the "pm2 start .. " command, pm2 will maintain the number of instances you specified in that command.
Running "pm2 delete all" and then "pm2 start app.js -i 5" should start five instances.

You should not use cluster mode with Node 0.10.x
