TPC! Memory Usage for WordPress

TPC! Memory Usage Dashboard Widget

TPC! Memory Usage Dashboard Widget

TPC! Memory Usage allows WordPress administrators to view the current and peak memory usage of the application, have e-mail notifications sent when memory usage exceeds the set level, and provides a detailed system information screen. This is extremely helpful when testing new plugins, or if there are a lot of modifications, plugins, or large language files. A strategic dashboard widget will provide a snapshot which includes the following information:

  • Monitor WordPress memory usage at various points
  • Ability to add custom checkpoints (WordPress actions where memory usage is recorded)
  • Log memory usage to files/database (checkpoints, when usage exceeds threshold, both, or none)
  • Keep track of all-time highest memory usage (shows date and peak usage)
  • E-mail notifications when memory usage exceeds set level w/ number of database queries
  • Completes basic security check to help prevent attacks and malware injections
  • View current memory usage
  • View current peak memory usage
  • Dashboard widget with memory meter
  • PHP memory limit
  • WordPress memory limit (defined in wp-settings.php)
  • System information screen for monitoring server, MySQL, PHP, and WordPress statuses and settings
  • Version: 0.9.1
  • Last Release: 1/10/2014

    I’ve changed my PHP and WordPress memory limit to 128M, but still when my memory usage goes over the old standard of 32MB I get a notification of shutdown. What’s this mean?

    Usage Sample: 24.67MB (10%)
    Peak Usage: 24.85MB (10%)
    All-Time: 35.26MB on 5/4/11 @ 4:14 am (shutdown)
    Load Averages: 1.74 1.36 1.42
    WP Memory Limit: 128M
    PHP Memory Limit: 128M

    Hi, We have been getting regular internal server errors until I bumped memory to 128mg but still see load averages from 2 to 4 on this server. My question is: What does the shutdown mean?

    Usage Sample: 40.22MB (31%)
    Peak Usage: 40.34MB (32%)
    All-Time: 44.75MB on 5/29/11 @ 1:13 am (shutdown)
    Load Averages: 3.05 2.97 2.98
    WP Memory Limit: 128M
    PHP Memory Limit: 128M

    We have a few plugins installed but not so many as should be a problem. We’re on a cloud server, and I just wonder if there is enough power allocated to our hosting…

    Hi

    I like your plugin, but I am running into some problems, I do not know if it is the TPC plugin or not, but when I disable TPC, then the error goes away.

    I get this error message when activating the plugin Backup to Dropbox, when TPC is also active:
    Warning: require_once(Tpcmem/Log.php): failed to open stream: No such file or directory in /www/wp-content/plugins/tpc-memory-usage/tpcmem-core.php on line 26 Fatal error: require_once(): Failed opening required ‘Tpcmem/Log.php’ (include_path=’/www/wp-content/plugins/wordpress-backup-to-dropbox/PEAR_Includes:.:/usr/local/lib/php’) in /www/wp-content/plugins/tpc-memory-usage/tpcmem-core.php on line 26

    When I deactivate TPC then I can activate Backup to Dropbox with out any problems.

    Can you help me? Thanks

    Hi chris,

    GREAT plugin.

    Still works fine in WP 3.2 but wanted to let you know that the progress bar doesn’t show the actual amount it is filled up anymore. It gives the % but doesn’t fill with colour. probably just a CSS thing in WP 3.2.

    Let me know if you see this too?

    Ross :)

    I have changed my php.ini file and the memory data does not change as well as the security check is not reading the changes.

    Thank you kindly for your support and plugin.

    Great Plugin!!
    I have a problem actually, I have a hosted website in 1and1.
    I believe the memory limit is 40 and that is what your plugin says. I have set a WP limit of 64M.
    However, the System Overview graph and the percentage are made of a 256M scale so I have a little percentage (27,17MB -11%- with 15 plugins by the way).
    How can I change the 256M scale to 40M??
    Thanks!

    Change the php.ini file.

    Hi Chris,

    Thanks for creating this plugin. I’m a bit confused as to what I’m seeing reported, however. It says I’m using 20M of my 32M available, yet it says this is 9%, which it clearly isn’t. I tried messing with the numbers by adjusting my php.ini and wp-config files, and it seems that no matter what I change, it always says 9%. I’m also not seeing anything in the Reports section (“Sorry, we did not find any records”, no matter where I look). I’m running WP v3.1.4.

    Can I add to the feature request? Allow for specific plugin memory utilization.

    What would be cool is a graph showing total memory used and how it breaks down by core wordpress and specific plugins.

    If this can be done via “Adding new actions/hooks” then some additional documentation/explanation regarding this would be useful.

    Thanks

    This is one great plugin. Wow. Thank you!

    I don’t understand the full ramifications of every warning and notification, but the plugin makes transparent critical data that I never had access to before so easily and conveniently. And it is all logged.

    I love this plugin. LOVE. Thank you.

    FYI – Since the latest update, your plugin causes a 500 error on all of my wordpress sites in a multisite install, at least when activated at the network level.

    Hi,

    Am trying to track down the culprit for high-memory usage on a client website and am making use of your most excellent plugin to do it.

    There is a previous comment where you say:

    “You can figure out how much memory a specific plugin is using by adding new actions/hooks. If the plugin doesn’t have any actions, you can add some at the various points where you want to make measurements”

    Can you direct me to some instructions for how to do this? I am not sure what adding checkpoints means, or how to add them for specific plugins.

    Any and all help greatly appreciated, thanks!

    John

    Hi Hi,

    it is a very useful plugin, but the way you include your javascript and css files causes a notice in debug-mode: “Notice: wp_register_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or init hooks… (This message was added in version 3.3.)..”. When i changed it to:

    function tpcmem_load_js_and_css() {
    wp_register_script(‘tpcmem’, plugins_url(‘tpc-memory-usage/js/tpcmem.js’), array(‘jquery’), TPCMEM_VERSION, true);
    wp_enqueue_script( ‘tpcmem’ );
    wp_register_script(‘tpcmem-overview’, plugins_url(‘tpc-memory-usage/js/overview.js’), array(‘jquery-ui-tabs’), TPCMEM_VERSION, true);
    wp_enqueue_script ( ‘tpcmem-overview’ );
    wp_register_script(‘tpcmem-tablesorter’, plugins_url(‘tpc-memory-usage/js/jquery.tablesorter.min.js’), array(‘jquery’), ’2.0.3′, true);
    wp_enqueue_script(‘tpcmem-tablesorter’);
    wp_register_script(‘tpcmem-reports’, plugins_url(‘tpc-memory-usage/js/reports.js’), array(‘tpcmem-tablesorter’), TPCMEM_VERSION, true);
    wp_enqueue_script(‘tpcmem-reports’);
    wp_register_style(‘tpcmem’, plugins_url(‘tpc-memory-usage/css/tpcmem.css’), array(), TPCMEM_VERSION);
    wp_enqueue_style( ‘tpcmem’);
    }

    add_action(‘admin_enqueue_scripts’, ‘tpcmem_load_js_and_css’);

    all works fine. Maybe a little suggestion for the next release?

    I have solved the missing styles on bar graph, you need to edit tpcmem-template.php and replace background-color with background on the line:

    <div class=”widget” id=”tpcmem_pbar” style=”width: %; background-color: ;”>

    In the absence of input from our intrepid author, I went ahead and made a few minor changes so that the plugin is fully compliant with WordPress 3.8.

    http://dev.imperativeideas.com/plugins/tpc-memory-usage.zip

    I’d love to see what you had in mind for updates, even if they are unfinished.

    Changes:

    library/Tpcmem/Log.php
    + 214: made getInstance() a static function

    tpcmem.css
    + 7: floated progress bar to the left
    + Corrected all relative image paths

    tpcmem-admin.php
    + 31-52: removed script enqueue logic

    tcpmem.php
    + Added script registration and enqueue to the admin_enqueue_scripts hook
    + Retained old conditional logic
    + Moved enqueue logic so that it sits next to the regitration
    + Wrapped script registration into a function.
    + Added a default condition when $_GET['page'] is not set
