tpc-memory-usage

I have this on all my blogs, and have had for years. Initially I installed it because my site was failing because of too much memory usage, but it also provides lots of information about your installation and software versions. I also appreciate the security evaluation. There are batter dedicated security tools, but this is a nice starting point. There is a setting to notify you if your blog usage exceeds a specified value. You can set it at whatever value you want, and it won't flood your mailbox unless you set it too low. Here are the features it provides: It gives you a compact overview of memory usage and system load averages on the WordPress dashboard It will tell you your server software and version, your IP address, your site's IP address, your document root folder It gives you select PHP settings, including the version and your upload limit It gives you select MySQL information including your hostname, MySQL version, and uptiome It displays a long list of WordPress settings It Scans 10 system security concerns and notifies you of what is right, and what could be improved. Explanations are provided.

As other users have stated, this plugin floods your inbox with hundreds of warning emails. These warnings are generated whenever your WP uses anything more than the default 32 MB memory limit, no matter if you've set the limit higher.
