Drupal: where does this tab "Track" come from?

I've noticed there is one more tab in my edit-content pages in Drupal.

Could you tell me which plugin added it ?

I 开发者_如何学JAVAactually need to know step by step how can I disable such tab

thanks

besides tracker.module (and, as mingos said, possibly other contrib modules), a "Track" tab is also added (to nodes) by statistics.module, statistics_menu().

UPDATE: this tab is only visible to users with "access statistics" permissions, so just adjust your site's permissions accordingly. as user #1 you will always see it, though.

you can, of course, just disable statistics.module.

Either Tracker (core module) or Tracker 2 (add-on) adds such a tab, but I've noticed it only on user profile pages.
