not authorized on admin to execute command

[silveraignacio]

Hello! I'm fightin with this issue since many months ago. I have configured the user admin with its respective password, but I'm getting the following issue:

Traceback (most recent call last):

The weird here is i'm accessing mongo db as admin user, so I cannot understand why it haven't got permission to get currentOp.

you need create mongodb user with root priveleges

db.createUser(
  {
    user: 'admin',
    pwd: 'password',
    roles: [ { role: 'root', db: 'admin' } ]
  }
);

like this
