Mongodb perm

[Jenkler]

I use mongodb, but i get this

"not authorized on nodebb_se_dev to execute command { serverStatus: 1 }"

What perm is recommended for the nodebb users, I want it as safe as possible.

I have this:

db.createUser( { user: "myuser", pwd: "<Enter in a secure password>", roles: [ "readWrite" ] } )

I found this

http://dba.stackexchange.com/questions/121832/db-serverstatus-got-not-authorized-on-admin-to-execute-command

But i don't want to add any rights to the admin DB only nodebb_se_dev. But the serverstatus is only for the admin db or what?

What role am I missing?
