Attention

TYPO3 v8 has reached its end-of-life March 31st, 2020 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.

There is no further ELTS support. It is recommended that you upgrade your project and use a supported version of TYPO3.

The LogRecord model

All logging data is modeled using \TYPO3\CMS\Core\Log\LogRecord.

This model has the following properties:

requestId

A unique identifier for each request which is created by the TYPO3 bootstrap.

created

The micro-timestamp when the record is created.

component

The name of the logger which created the LogRecord, usually the fully qualified class name where the Logger has been instanciated.

level

An integer severity level from \TYPO3\CMS\Core\Log\LogLevel.

message

The log message string.

data

Any additional data, encapsulated within an array.

The API to create a new instance of LogRecord is \TYPO3\CMS\Core\Log\Logger:log() or one of the shorthand methods.

LogRecord implements the ArrayAccess interface so that the properties can be accessed like a native array, for example: $logRecord['requestId']. It also implements a __toString() method for your convenience, which returns the log records as a simplified string.

A LogRecord can be processed using LogProcessors or LogWriters. LogProcessors are meant to add values to the data property of LogRecord. For example, if you would like to add a stack trace, use \TYPO3\CMS\Core\Log\Processor\IntrospectionProcessor.

LogWriters are used to write a LogRecord to a particular target, for example a log file.
