Logging

A logger writes log entries to a destination using a specific format.

Destinations

• Echo
• Email
• File
• Null
• Slack
• Socket
• StErr
• StdOut
• Webhook

Formats

• CSV
• HTML
• HTMLEmail
• JSon
• PlainText
• Raw

Multiplexer

A LogMux implements the ILogger interface but contains and writes to multiple logs simultaneously. Each logger can have a separate run level so only certain logs may be written to depending on the log level.

Logger Singleton

The logger singleton is a LogMux wrapper that exists as a singleton/cross cutting concern so it can be accessed anywhere in the code base.

The default log is the Echoer using plain text format.

Examples

Logger Singleton

The quickest way to get started is using the singleton facade:

// Optionally set the runlevel..
Log::setRunLevel( 'debug' );

Log::debug( "Log message." );

Slack

To configure slack:

$Log = Log::getInstance();

$Slack = new Slack(
    new PlainText( true )
);

$Slack->open(
    [
        'endpoint' => env( 'LOG_SLACK_WEBHOOK_URL' ),
        'params' => [
            'channel'  => env( 'LOG_SLACK_CHANNEL' ),
            'username' => 'Log'
        ]
    ]
);

$SlackLogger = new Logger( $Slack );
$SlackLogger->setRunLevel( 'error' );
$Log->Logger->addLog( $SlackLogger );

In this example, any log with a level of ERROR or higher will be written to the slack channel.

Contexts

Log::setContext( 'UserId', $UserId );
Log::setContext( 'SessionId', $SessionId );

Log::info( "New login." );

Outputs:

[2022-06-03 12:00:00][Info] [UserId=15, SessionId=1234] New Login

$Log = Log::getInstance();

$Slack = new Slack(
    new PlainText( true )
);

$Slack->open(
    [
        'endpoint' => env( 'LOG_SLACK_WEBHOOK_URL' ),
        'params' => [
            'channel'  => env( 'LOG_SLACK_CHANNEL' ),
            'username' => 'Log'
        ]
    ]
);

$SlackLogger = new Logger( $Slack );
$SlackLogger->setRunLevel( 'info' );

Log::addToMux( 'RealTime', $SlackLogger );

Log::mux( 'RealTime' )->info( "Slack notification." );
