Connecting to remote PM2

I am having trouble talking to PM2 instances on a remote host. Wondering if someone could help set me straight.

I have set up an env variable called: PM2_BIND_ADDR
[root@cp-bus-api app]# echo $PM2_BIND_ADDR
0.0.0.0

But when I start PM2 there is nothing on port 6666
[root@cp-bus-api app]# netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:22 0.0.0.0:\* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:\* LISTEN
tcp 0 0 0.0.0.0:443 0.0.0.0:\* LISTEN

I am running the latest version of PM2:
[root@cp-bus-api app]# pm2 -v
0.11.0

Once I actually have something running on port 6666 I assume I will need to configure the firewall to let my PM2-web server to see it. I'm just not having much luck getting pm2 to actually open up and start doing something on that port.
