What is null(autopublish) publication?

Have you wondered about the publication which shows as null(autopublish) in Monti APM?

This has no relationship with the autopublish package. This is about null unnamed publications. If you create a publication with the name as null,
it will be automatically published to clients whenever a session is created. See the following example:

Meteor.publish(null, function() {
  return Posts.find({});
});

Meteor uses this kind of publication to send user data to the client. That's how you are able to access user information with Meteor.user().

That's what Monti APM shows as the null(autopublish) publication.
