db.adminCommand('listDatabases')
db.getMongo().getDBNames().forEach(function(db){print(db)})

Удалить базу:

db.dropDatabase()

Добавить пользователя:

db.createUser({user:"username", pwd:"password", roles:[{role:"role", db:"database"}])
db.createUser({user:"root", pwd:"password", roles: [ "root" ]})

Backup / Restore

Резервная копия (база graylog):
