use Monolog\Logger; use Monolog\Handler\StreamHandler; // create a log channel $log = new Logger('name'); $log->pushHandler(newStreamHandler('path/to/your.log', Logger::WARNING)); // add records to the log $log->addWarning('Foo'); $log->addError('Bar');

Core concepts

Each Logger instance has a channel and a log processor stack. Every time you add a log record, it will be sent to the log processor stack. You can create manyLogger，Each Logger defines a channel (db, request, route), and each Logger has many log processors. These channels filter logs.

Each log processor has a Formatter (a built-in log display format processor ). You can also set the log level.

Log Level

1. DEBUG: Detailed debug information
2. INFO: events of interest. Like user logon, SQL logs
3. NOTICE: A normal but significant event.
4. WARNING:When an exception occurs, an outdated API is used.
5. ERROR: an ERROR occurs during running. The ERROR must be recorded and monitored, but the ERROR does not need to be handled immediately.
6. CRITICAL: CRITICAL errors, such as application component unavailability.
7. ALETR: an error that requires immediate action, such as the failure of the entire website and unavailability of the database. At this time, the trigger will notify you via SMS,
