This is a free WordPress plugin for system monitoring. It regularly checks and reports for system, database and server settings. It shows warnings whenever the system overloads or something goes down.

Features of Strictly System Check:
- The option to choose which URL is scanned when the system check is carried out
- The ability to search for a key phrase or piece of text in the source code and to raise a report if it's not found
- The system also checks the server load and can raise a report if it's over a specified limit
- The system also checks the database load to ensure that it's not overloaded and not running too many queries
- The system is not suffering poor performance due to fragmented table indexes
- Reports on the number of connections, queries, reads, writes, aborted connections, slow queries

What's new in this version:
- Added new database reports such as the percentage of queries that are slow, the number of joins without indexes, the number of reads & writes and much more
- Changed the formatting and layout of the admin page
- Added an extra test for MySQL version in the test configuration option
- Added code to inform the user if the plugin gets updated with new options so that they know to re-configure their plugin
