TPC! Memory Usage Dashboard Widget
NEW RELEASE PLANNED FOR JAN. 2011, COME BACK SOON FOR MORE INFO!
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
- Last Release: 1/16/2010
Nice plugin
slow in response, wasn’t subscribed to the comment thread or something.
I’ve got 30 separate wp installations on a shared server.
Back when I made the comment, I was getting slightly (very slightly) different results from site to site. But these days with the latest version, I’m seeing the same exact numbers, which makes me think I’m getting a server level number.
not good or bad, just important to understand.
So overall that leaves me with two things in my wish list, which maybe this plugin can some day cover and maybe not.
1. Would love to see an option to share information back to you or to some service where we could start to see some performance stats on many different hosts, configurations, systems etc. which might help people better benchmark what is a good server or php configuration etc.
2. Would love to see some details that might help me understand something along the lines of active services (like how much a plugin is running up the system so that I could trouble shoot bad or resource heavy plugins). Not something I need all the time, thank god, but in a pinch, sure would help.
3. Where’s your donate button? I can afford to pay for development, but can definitely tip (hopefully along with lots of other people to help fuel your fire!)
Brett,
I absolutely LOVE your ideas. I might want to talk with you about this more once I start delving into the next version, if you’d be open to that. Great feedback.
(As for donate button: Settings page, upper-right corner)
Thanks!

Hi Chris,
I liked this plugin and I really have very limited memory so I have to keep an eye on the usage. After installing the plugin the Admin panel direction changed from RTL ( Arabic ) to LTR, font changed from Tahoma to the default English font which isn’t suitable for Arabic scripts, And the appearance damaged a lot, I can contribute and Translate the po file but please change it to RTL and solve everything If possible .
Thank you for this really nice plugin. But I have a problem with the e-mail notification: I’m running WordPress with a 40M memory_limit but the plugin sends me an e-mail, everytime wordpress uses more than 32M
I changed the value in tcp-memcore.php on line 102 to 40 but that won’t solve my case.
Hi Gunther,
You can change this setting within the options interface inside the WordPress admin panel. Hope that helps!
Thanks,
Chris
Thanks for the plugin,
In the “setting” area, in “Notifications” tab, i set the mail of server admin in the “Recipients” field to Notify him if memory usage exceeds, but he don’t receive any notification, but me the “admin” of the webiste YES.
pls how can i notify the admin about the exceed of memory?
Thanks
I installed the plugins. I get emails whenever memory usage is exceeds 16M. It comes in pulses. But how do I figure out what’s causing the memory usage so I can fix it?
I’m not getting any reports. I chose “wrote to log when memory exceeds 16 M”. I chose “file”. Where are the logs? Should I check database?
Hi,
Nice plugin !
I added define(‘WP_MEMORY_LIMIT’, ’64M’); to my wp-config.php , but In the Dashboard I get :
WP Memory Limit: 32M
PHP Memory Limit: 64M
Also, what do the Load Averages: 1.03 1.97 2.5 actually mean ?
Regards,
D.
I have having the same issues as many people who have commented here. I’d like to know exactly what is causing the issue and cant find answers on the net about this. This plugin doesn’t look like it can tell me which plugin is taking up so much memory or bring my server down.
Hey Winter,
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.
Thanks,
Chris
Hey D.,
Check out this article on Wikipedia… should answer your questions about load averages.

Sincerely,
Chris S.
Under System Overview/Security, I had several Warnings! and Problem! messages.
Where do I go to correct these?
I have looked everywhere for months for the answer to my memory overage problem. This is the first site that effectively addresses the problem. You’re on to something here, keep at it!
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!
I have two WordPress 3.0.5 blogs with two different hosting companies. I set them up so that each has the same plug-ins installed: Akismet and TPC! Memory Usage, and both to use the WordPress “default” theme based on Kubrik.
When I display the dashboard for one, TPC! says the peak memory is 22MB and the other one says 15 MB.
So is this a real result or some kind of a quirk with how PHP tracks memory usage? (The small usage site is PHP 5.2.14 and the other 5.2.15.) If it’s real, which number is out of line?
Thanks for the totally useful plug-in.
Any news about the release planned for January 2011? If there’s a beta available I’d be happy to test it.
This could happen for a variety of reasons. You are correct that the version difference can certainly make a difference, but granted you are using two different hosting companies, it is likely that they also have different PHP configurations. Even with dedicated (or virtual dedicated) hosting environments, you’ll find subtle differences. There could even be differences between operating system versions. As far as PHP versioning is concerned, see the release logs for potential performance changes:
http://php.net/releases/5_2_14.php
http://php.net/releases/5_2_15.php
I hope this helps!

I am using your great plugin to troubleshoot DreamHost Server side cuts because of memory hogs. Somehow your plugin seems to send quite a few reports to the site admin’s e-mail address. I do not really need that. How can that be turned off?
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.
Change the php.ini file.
When I activate it; can’t get to it’s status page, the url showing up is:
http://www.domain.net/wp-admin/admin.php?page=D:/Hosting/4738447/html/SiteName/wp-content/Plugins/tpc-memory-usage
that is the physical path it’s in; but that seems a goofy url. Could that be the problem with the info not showing up?
hi thanks for the plugin, is there any new release for the new wordpress version?
thanks
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
Hi Chris,
any news regarding the new version of TPC?
Thanks in advance
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.
Where can I update the scale of the graphics, it is always fixed to 256MB
Thanks
I have giving you some rep at WPMU DEF

Hope this helps
Cool Plug
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!

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?
Daniel
Chris, is this plugin still in active development?
I have some fixes for broken CSS and proper registering of scripts.
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: ;”>
