PHP Livelog

What it does

This small tool should simplify the developer's life by offering the possibility to follow the logs of a web application live.

You don't have to tail and grep the logfiles direct on the machine or to download it. The logs will only be written for the current session, so you see only the log of your own requests.

Install

The suggested install-method is to use composer composer req aseemann/php-livelog. After installing the package you have to set a symlink to the web folder in your public directory e.g. ln -s vendor/aseemann/php-livelog/web docroot/livelog

Now you can open the log dashboard in your webbrowser under the path of the symlinks. e.g domian.tld/livelog

For easier setup you can add this to your composer.json file in the scripts section.

{
    "scripts": {
        "set-symlinks": [
            "ln -sfT ../vendor/aseemann/php-livelog/web docroot/livelog"
        ],
        "post-install-cmd": [
            "@set-symlinks"
        ],
        "post-update-cmd": [
            "@set-symlinks"
        ]
    }
}

How to use

To send logs to the log page integrate the logger into your scripts as described below.

$logger = new \ASeemann\PhpLiveLog\Logger('Application Name', 'LoggerName');

$logger->info('A small info massage');

$logger->notice('Some notice', ['data' => 'data for notice']);

Afterward the logs should appear on the logging page grouped by the request.

Connectors

For the easy integration in some projects there are also connectors available. So you only have to add some configuration in your application and all logs of your app will appear on the logging page.

TYPO3

Add the following lines to your AdditionalConfiguration.php

$GLOBALS['TYPO3_CONF_VARS']['FE']['debug'] = true;
$GLOBALS['TYPO3_CONF_VARS']['BE']['debug'] = true;
$GLOBALS['TYPO3_CONF_VARS']['SYS']['enable_DLOG'] = true,
$GLOBALS['TYPO3_CONF_VARS']['SYS']['enable_errorDLOG'] = true,
$GLOBALS['TYPO3_CONF_VARS']['SYS']['enable_exceptionDLOG'] = true,
$GLOBALS['TYPO3_CONF_VARS']['SYS']['systemLogLevel'] = 0,

if (false === is_array($GLOBALS['TYPO3_CONF_VARS']['LOG']['writerConfiguration'][\TYPO3\CMS\Core\Log\LogLevel::DEBUG])) {
    $GLOBALS['TYPO3_CONF_VARS']['LOG']['writerConfiguration'][\TYPO3\CMS\Core\Log\LogLevel::DEBUG] = [];
}

$GLOBALS['TYPO3_CONF_VARS']['LOG']['writerConfiguration'][\TYPO3\CMS\Core\Log\LogLevel::DEBUG]
[\ASeemann\PhpLiveLog\Connector\TYPO3\LogWriter::class] = [
];

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_div.php']['devLog'] = [];
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_div.php']['devLog'][]
    = \ASeemann\PhpLiveLog\Connector\TYPO3\DevLogger::class . "->devLogger";

The lines you take from here may vary depending on you typo3 installation.

You have also the possibility to exclude some loggers. So you can keep the focus on what you want to see. To exclude the logger pass the option ignorePattern to the log-writer.

Example: (Ignore all logger wich contains Frontend in their names )

$GLOBALS['TYPO3_CONF_VARS']['LOG']['writerConfiguration'][\TYPO3\CMS\Core\Log\LogLevel::DEBUG]
[\ASeemann\PhpLiveLog\Connector\TYPO3\LogWriter::class] = [
    'ignorePattern' => '.*Frontend.*'
];

Todos

• Add formatter for context
• escape tags in context
• Add more connectors.
