Should PM2 God Daemon always be running?

Question

I use pm2 to deal with node projects. Even when all projects are stopped via pm2, I see that pm2 God Daemon is always running and consuming about ~27M Ram. Here how it looks on ps aux: nodeuser 2577 ? Ssl 18:02 0:01 PM2 v0.15.10: God Daemon

The question is, is it built to be that way? Should pm2 God Daemon always be running? However if it is the case, I would like to know why because it didn't make sense to me.

Can I kill pm2 God Daemon via pm2? Or simply kill with kill -9 pid?

With pm2 you can kill the god daemon with

pm2 kill

Thats bad, as it nukes you config as well. Not ideal if you want to restart the god daemon under systemd rather that stand alone but in its existing state – Danella

@Danella pm2 will utilize saved config and will resurrect daemonized processes if pm2 save and pm2 startup have been used. How will pm2 kill impact systemd in such case? – Rella

Depending on how the service is setup it will either restart or fault – Danella
