Manual:$wgDisableCounters/en

Details
  determines whether or not to update the number of times a page has been viewed. If  is set to false, each page will have a counter in its footer saying: ""

This setting also determines whether  is available.

This variable is initialized in. The initial value is. To override the default value, add the line  to the file.

The value of the counter is updated in  in the function. (In a previous version, this was  in the function  .) The variable  is also referred to in other script files.

Alternatives
If performance problems due to high hit counts updating the  table is a concern, a less dramatic alternative to disabling them may be to tweak.

You can also retrieve such statistics through your apache (or squid if using squid caching) request logs.

Disabled in 1.25.0. See Requests for comment/Removing hit counters from MediaWiki core and other alternatives
