System Modules

In the User Management chapter we already visited the Access and Backend Users module. Here is a brief presentation of the other modules.

Install

The Install Tool is presented in the Installation Guide. It can be accessed directly from the TYPO3 CMS backend.

Log

The TYPO3 CMS backend traces a number of actions performed by users: login, cache clearing, database entries (creation, update, deletion), settings changes, file actions and errors. A number of filters are available to help digging into this data.

DB check

The Database (DB) Check module offers four functions related to the database and its content.

Overview of the DB check functions
Record Statistics
Simple shows a count of the various records in the database, broken down by type for pages and content elements.
Relations
Checks if some relations are empty or broken, especially with regards to files.
Search
A tool to seach through the whole database. It offers an advanced mode which is nearly a visual query builder.
Check and update global reference index
TYPO3 CMS keeps a record of relations between all records. This may get out of sync when some operations are performed without the strict context of the backend. It is therefore useful to update this index regularly.

Configuration

The Configuration module can be used to view the various configuration arrays used by TYPO3 CMS. It is not the goal of this tutorial to described the role of each of these arrays, you discover their function as you dig deeper into TYPO3 CMS. Let's just mention that the $GLOBALS['TYPO3_CONF_VARS'] contains global configuration values that you may have set in the Install Tool.

Reports

The Reports module contains information and diagnostic data about your TYPO3 CMS installation. It is particularly worthwhile to regularly check out the "Status Report" as it will inform you about bad configuration, security issues, etc.
