Dev Monitor


Dev Monitor optionally adds SQL Query, Memory Usage, Execution Time, Javascript, CSS, WordPress Conditionals, and included theme and plugin PHP file information to the admin bar for users with the appropriate permissions. Use this plugin to aid your development by making it easy to see which files are included and where.

What You’ll See

Check out the screenshots section for pictures of what you get.

  1. Queries: With SAVEQUERIES enabled you’ll see execution time, the query, and the reference location (ordered by time). Without SAVEQUERIES enabled you’ll simply see the number of queries.
  2. Execution Time: How long it took to load the page
  3. Memory: How much memory was used
  4. PHP Includes: Which php theme files and plugin files were included
  5. Javascripts: Javascript handles and file sizes for enqueued scripts
  6. CSS: CSS handles and file sizes for enqueued scripts
  7. Widgets: A list of Active (not necessarily used) and Inactive widgets
  8. Conditionals: 2 Lists of wordpress conditionals run on the current page. True/False conditionals can be used without parameters. Page Specific will return true for the current page when run with the supplied parameters.


  • Dev Monitor adds some information to your admin bar about Queries, Execution Time, Memory, Theme/Plugin PHP Includes, Javascript includes, CSS includes, and Widgets.
  • Mouse over the Dev Monitor Stats to get added information. Here you can see the Javascript handles for all of the enqueued scripts.
  • The included PHP Files located in your themes or plugin directory.
  • A list of queries (assuming SAVEQUERIES has been defined)
  • The CSS handles for all of the enqueued styles.
  • True/False conditional menu
  • Page Specific conditional menu


  1. Upload the plugin to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Visit Settings > Dev Monitor to choose which options you would like to display.


Why can’t I see the queries?

Make sure SAVEQUERIES is defined in your wp-config.php. Add the following line:



Easy, Intuitive, Informative. Great Tool!

I just randomly stumbled across this plugin and it is excellent. Very similar to Query Monitor, but much simpler and easy to read all the data. If you want to monitor all your performance factors but Query Monitor is a bit overkill, this is a great option.

Works great! Simple, light, effective and quick to access!

Great plugin.

If yo need something lighter or not as in depth as Query Monitor, this is the plugin to use.

It is much easier to view this data than in Query Monitor because Query Monitor outputs a lot more data in a much larger interface.

I’ve used this plugin for a little over a year. No bugs, no issues and is increases development workflow for sure.
