Once the Memory Usage Monitor plugin is activated, activating or deactivating any other plugin will display the memory used by that plugin. e.g:
Memory usage for WP Memory: 0.02 MB
For accurate memory usage breakdown for each plugin, you must activate or deactivate them individually; you will not see memory usage when bulk activating plugins.

Memory Usage Monitor

Displays memory/RAM usage for each plugin as they are activated and deactivated.

Logs memory usage as users browse your website providing latest logs and flagged logs (when memory usage is over specific percentages).
For users who have specific capabilities (e.g. administrators) a memory meter is shown in the admin bar showing memory usage as the website and dashboard is navigated and includes several configuration options.

<h4>Usage</h4>
After installation memory usage will be logged for any user as they browse the website and dashboard, you can see the logs via the Memory Meter menu in the WordPress dashboard.
By default the memory meter will be shown in the admin bar if you are logged in as user with the <code>manage_options</code> capability such as an administrator (the capability can be modified if required, see the configuration tab via the Memory Meter page).
In this scenario you will see the meter in the admin bar at the top of your WordPress dashboard and the frontend of your website. Note that there is a user profile setting in WordPress to enable the admin bar, it is enabled by default, if this is not enabled you will not be able to view the memory meter in the admin bar.
If you hover over the memory meter you will see a number of options, such as logs and configuration. In addition to the admin bar, a menu item is included in your WordPress dashboard to give access to the logs, confirguration, etc.
Note that the memory meter doesn’t need to be displayed to ensure memory usage is logged, this is done regardless of whether the memory meter is being displayed.
