Multisite Usage Scanner helps WordPress network administrators audit plugin usage across all sites in a multisite installation.
It provides a simple admin interface to: 
* List all active plugins per site 
* Identify unused plugins across the network 
* Export usage data for reporting or cleanup
This tool is especially useful for large networks with legacy plugins or unclear usage patterns.

As my WordPress network grew I found it challenging to track which plugins and themes were used on each site, and the only way to check was to visit each dashboard one at a time. What a hassle!
This plugin adds columns to your Network Admin on the Sites, Themes and Plugins pages to show which of your sites have each plugin and theme activated. Now you can easily determine which plugins and themes are used on your network sites and which can be safely removed.

Network Plugin Auditor

This is an indispensable tool for MS admins, since WordPress core doesn't include any tools for seeing which MS plugins are in use or by which sites.



Excellent tool

For multisite/network installations only.  Adds columns to your network admin to show which sites are using each plugin and theme.
