We are facing a performance issues on our environment, that is why we want to disable Sharepoint Web Analytics on sites. The main target is to disable web analytics only on specified site collections, but the farm feature and service should stay enabled. Is there any way we can disable site analytics on site collection? By disabling I mean, site shouldn't be processed by service application. I found similar topics, but all of them describes how to disable web analytics on farm, and we want to cut only specified sites.
First you can Find all activated Web Analytics Features in your Farm using PowerShell command & find how many are features available for Farm, for CA & for Site Collections. You need to loop through all web applications and site collections & get appropriate features to disable them.
Please follow this link to resolve your problem.
You need to modify the last PowerShell commands to disable the feature after getting it.
