Memory Meter


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.


  • Logs memory usage as users browse the website/dashboard
  • Current memory usage by file size
  • Current memory usage by percentage
  • Memory limit
  • PHP memory limit
  • PHP max execution time
  • WP memory limit
  • WP max memory limit
  • Latest memory usage logs
  • Flagged memory usage logs
  • Memory usage logs with page request info (Premium)
  • Memory usage in JS console (Premium)


After installation memory usage will be logged as any user browses the website, 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 manage_options 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.

Screen Sizes

  • Frontend: Where elements may be displayed on the frontend they will fit within the screen width

Where can I find the memory meter?

See the usage information above.

How do I change the memory file size to KB or GB rather than MB?

You can use the wpmm_memory_meter_file_size_format filter hook.

What percentage of memory usage will make the meter change color?

When your website is using greater than 75% of allocated memory the meter will change to orange (warning), if greater than 90% it will change to red (bad). If you want to change these default percentages you can use the wpmm_memory_meter_memory_usage_percentage_warning and wpmm_memory_meter_memory_usage_percentage_bad filter hooks.

Who can see the memory meter/can I make it visible to specific users?

The memory meter shows by default for any user with the manage_options capability, which is usually administrators. You can change the capability required to see the memory meter by using the wpmm_memory_meter_capability filter hook.

Can I disable the memory meter colors?

Yes, you can disable the colors using the wpmm_memory_meter_memory_usage_colors filter hook.

Can I disable logs?
