Meteor getting userId in startup function

How can I get the userId in Meteor.startup function any ideas? I need it to run a loop that pings every 10 seconds but all I get is Error: Meteor.userId can only be invoked in method calls. Use this.userId in publish functions.

My code:

Meteor.startup(function() {
    console.log(Meteor.userId());
});

You're not likely to get the Meteor.userId() in the startup function because the data from subscriptions (such as who is logged in) will take a short while to arrive, by which time startup would have completed.

Use Tracker.autorun() instead:

Tracker.autorun(function() {
    if(Meteor.userId()) {
        ///
    }
});

Be careful this will run whever the user logs in as well. To ensure it only runs once you could use a Session that could store how many times its run, and stop it if it runs more than once.

The answer is clearly mentioned in the error message. By the way, you need to check whether logged in or not before trying to print.

Meteor.startup(function() {
    if (this.userId)
        console.log(this.userId);
});
