See the complete list of handlers below. Special handlers +allow you to build advanced logging strategies. + +This library implements the [PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md) +interface that you can type-hint against in your own libraries to keep +a maximum of interoperability. You can also use it in your applications to +make sure you can always use another compatible logger at a later time. +As of 1.11.0 Monolog public APIs will also accept PSR-3 log levels. +Internally Monolog still uses its own level scheme since it predates PSR-3. + +Usage +----- + +Install the latest version with `composer require monolog/monolog` + +```php +pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING)); + +// add records to the log +$log->addWarning('Foo'); +$log->addError('Bar'); +``` + +Core Concepts +------------- + +Every `Logger` instance has a channel (name) and a stack of handlers. Whenever +you add a record to the logger, it traverses the handler stack. Each handler +decides whether it fully handled the record, and if so, the propagation of the +record ends there. + +This allows for flexible logging setups, for example having a `StreamHandler` at +the bottom of the stack that will log anything to disk, and on top of that add +a `MailHandler` that will send emails only when an error message is logged. +Handlers also have a `$bubble` property which defines whether they block the +record or not if they handled it. In this example, setting the `MailHandler`'s +`$bubble` argument to false means that records handled by the `MailHandler` will +not propagate to the `StreamHandler` anymore. + +You can create many `Logger`s, each defining a channel (e.g.: db, request, +router, ..) and each of them combining various handlers, which can be shared +or not. The channel is reflected in the logs and allows you to easily see or +filter records. + +Each Handler also has a Formatter, a default one with settings that make sense +will be created if you don't set one. The formatters normalize and format +incoming records so that they can be used by the handlers to output useful +information. + +Custom severity levels are not available. Only the eight +[RFC 5424](http://tools.ietf.org/html/rfc5424) levels (debug, info, notice, +warning, error, critical, alert, emergency) are present for basic filtering +purposes, but for sorting and other use cases that would require +flexibility, you should add Processors to the Logger that can add extra +information (tags, user ip, ..) to the records before they are handled. + +Log Levels +---------- + +Monolog supports the logging levels described by [RFC 5424](http://tools.ietf.org/html/rfc5424). + +- **DEBUG** (100): Detailed debug information. + +- **INFO** (200): Interesting events. Examples: User logs in, SQL logs. + +- **NOTICE** (250): Normal but significant events. + +- **WARNING** (300): Exceptional occurrences that are not errors. Examples: + Use of deprecated APIs, poor use of an API, undesirable things that are not + necessarily wrong. + +- **ERROR** (400): Runtime errors that do not require immediate action but + should typically be logged and monitored. + +- **CRITICAL** (500): Critical conditions. Example: Application component + unavailable, unexpected exception. + +- **ALERT** (550): Action must be taken immediately. Example: Entire website + down, database unavailable, etc. This should trigger the SMS alerts and wake + you up. + +- **EMERGENCY** (600): Emergency: system is unusable. + +Docs +==== + +**See the `doc` directory for more detailed documentation. +The following is only a list of all parts that come with Monolog.** + +Handlers +-------- + +### Log to files and syslog + +- _StreamHandler_: Logs records into any PHP stream, use this for log files. +- _RotatingFileHandler_: Logs records to a file and creates one logfile per day. + It will also delete files older than `$maxFiles`. You should use + [logrotate](http://linuxcommand.org/man_pages/logrotate8.html) for high profile + setups though, this is just meant as a quick and dirty solution. +- _SyslogHandler_: Logs records to the syslog. +- _ErrorLogHandler_: Logs records to PHP's + [`error_log()`](http://docs.php.net/manual/en/function.error-log.php) function. + +### Send alerts and emails + +- _NativeMailerHandler_: Sends emails using PHP's + [`mail()`](http://php.net/manual/en/function.mail.php) function. +- _SwiftMailerHandler_: Sends emails using a [`Swift_Mailer`](http://swiftmailer.org/) instance. +- _PushoverHandler_: Sends mobile notifications via the [Pushover](https://www.pushover.net/) API. +- _HipChatHandler_: Logs records to a [HipChat](http://hipchat.com) chat room using its API. +- _FlowdockHandler_: Logs records to a [Flowdock](https://www.flowdock.com/) account. +- _SlackHandler_: Logs records to a [Slack](https://www.slack.com/) account. +- _MandrillHandler_: Sends emails via the Mandrill API using a [`Swift_Message`](http://swiftmailer.org/) instance. +- _FleepHookHandler_: Logs records to a [Fleep](https://fleep.io/) conversation using Webhooks. + +### Log specific servers and networked logging + +- _SocketHandler_: Logs records to [sockets](http://php.net/fsockopen), use this + for UNIX and TCP sockets. See an [example](https://github.com/Seldaek/monolog/blob/master/doc/sockets.md). +- _AmqpHandler_: Logs records to an [amqp](http://www.amqp.org/) compatible + server. Requires the [php-amqp](http://pecl.php.net/package/amqp) extension (1.0+). +- _GelfHandler_: Logs records to a [Graylog2](http://www.graylog2.org) server. +- _CubeHandler_: Logs records to a [Cube](http://square.github.com/cube/) server. +- _RavenHandler_: Logs records to a [Sentry](http://getsentry.com/) server using + [raven](https://packagist.org/packages/raven/raven). +- _ZendMonitorHandler_: Logs records to the Zend Monitor present in Zend Server. +- _NewRelicHandler_: Logs records to a [NewRelic](http://newrelic.com/) application. +- _LogglyHandler_: Logs records to a [Loggly](http://www.loggly.com/) account. +- _RollbarHandler_: Logs records to a [Rollbar](https://rollbar.com/) account. +- _SyslogUdpHandler_: Logs records to a remote [Syslogd](http://www.rsyslog.com/) server. +- _LogEntriesHandler_: Logs records to a [LogEntries](http://logentries.com/) account. + +### Logging in development + +- _FirePHPHandler_: Handler for [FirePHP](http://www.firephp.org/), providing + inline `console` messages within [FireBug](http://getfirebug.com/). +- _ChromePHPHandler_: Handler for [ChromePHP](http://www.chromephp.com/), providing + inline `console` messages within Chrome. +- _BrowserConsoleHandler_: Handler to send logs to browser's Javascript `console` with + no browser extension required. Most browsers supporting `console` API are supported. + +### Log to databases + +- _RedisHandler_: Logs records to a [redis](http://redis.io) server. +- _MongoDBHandler_: Handler to write records in MongoDB via a + [Mongo](http://pecl.php.net/package/mongo) extension connection. +- _CouchDBHandler_: Logs records to a CouchDB server. +- _DoctrineCouchDBHandler_: Logs records to a CouchDB server via the Doctrine CouchDB ODM. +- _ElasticSearchHandler_: Logs records to an Elastic Search server. +- _DynamoDbHandler_: Logs records to a DynamoDB table with the [AWS SDK](https://github.com/aws/aws-sdk-php). + +### Wrappers / Special Handlers + +- _FingersCrossedHandler_: A very interesting wrapper. It takes a logger as + parameter and will accumulate log records of all levels until a record + exceeds the defined severity level. At which point it delivers all records, + including those of lower severity, to the handler it wraps. This means that + until an error actually happens you will not see anything in your logs, but + when it happens you will have the full information, including debug and info + records. This provides you with all the information you need, but only when + you need it. +- _WhatFailureGroupHandler_: This handler extends the _GroupHandler_ ignoring + exceptions raised by each child handler. This allows you to ignore issues + where a remote tcp connection may have died but you do not want your entire + application to crash and may wish to continue to log to other handlers. +- _BufferHandler_: This handler will buffer all the log records it receives + until `close()` is called at which point it will call `handleBatch()` on the + handler it wraps with all the log messages at once. This is very useful to + send an email with all records at once for example instead of having one mail + for every log record. +- _GroupHandler_: This handler groups other handlers. Every record received is + sent to all the handlers it is configured with. +- _FilterHandler_: This handler only lets records of the given levels through + to the wrapped handler. +- _SamplingHandler_: Wraps around another handler and lets you sample records + if you only want to store some of them. +- _NullHandler_: Any record it can handle will be thrown away. This can be used + to put on top of an existing handler stack to disable it temporarily. +- _PsrHandler_: Can be used to forward log records to an existing PSR-3 logger +- _TestHandler_: Used for testing, it records everything that is sent to it and + has accessors to read out the information. + +Formatters +---------- + +- _LineFormatter_: Formats a log record into a one-line string. +- _HtmlFormatter_: Used to format log records into a human readable html table, mainly suitable for emails. +- _NormalizerFormatter_: Normalizes objects/resources down to strings so a record can easily be serialized/encoded. +- _ScalarFormatter_: Used to format log records into an associative array of scalar values. +- _JsonFormatter_: Encodes a log record into json. +- _WildfireFormatter_: Used to format log records into the Wildfire/FirePHP protocol, only useful for the FirePHPHandler. +- _ChromePHPFormatter_: Used to format log records into the ChromePHP format, only useful for the ChromePHPHandler. +- _GelfMessageFormatter_: Used to format log records into Gelf message instances, only useful for the GelfHandler. +- _LogstashFormatter_: Used to format log records into [logstash](http://logstash.net/) event json, useful for any handler listed under inputs [here](http://logstash.net/docs/latest). +- _ElasticaFormatter_: Used to format log records into an Elastica\Document object, only useful for the ElasticSearchHandler. +- _LogglyFormatter_: Used to format log records into Loggly messages, only useful for the LogglyHandler. +- _FlowdockFormatter_: Used to format log records into Flowdock messages, only useful for the FlowdockHandler. +- _MongoDBFormatter_: Converts \DateTime instances to \MongoDate and objects recursively to arrays, only useful with the MongoDBHandler. + +Processors +---------- + +- _IntrospectionProcessor_: Adds the line/file/class/method from which the log call originated. +- _WebProcessor_: Adds the current request URI, request method and client IP to a log record. +- _MemoryUsageProcessor_: Adds the current memory usage to a log record. +- _MemoryPeakUsageProcessor_: Adds the peak memory usage to a log record. +- _ProcessIdProcessor_: Adds the process id to a log record. +- _UidProcessor_: Adds a unique identifier to a log record. +- _GitProcessor_: Adds the current git branch and commit to a log record. +- _TagProcessor_: Adds an array of predefined tags to a log record. + +Utilities +--------- + +- _Registry_: The `Monolog\Registry` class lets you configure global loggers that you + can then statically access from anywhere. It is not really a best practice but can + help in some older codebases or for ease of use. +- _ErrorHandler_: The `Monolog\ErrorHandler` class allows you to easily register + a Logger instance as an exception handler, error handler or fatal error handler. +- _ErrorLevelActivationStrategy_: Activates a FingersCrossedHandler when a certain log + level is reached. +- _ChannelLevelActivationStrategy_: Activates a FingersCrossedHandler when a certain + log level is reached, depending on which channel received the log record. + +About +===== + +Requirements +------------ + +- Monolog works with PHP 5.3 or above, and is also tested to work with HHVM. + +Submitting bugs and feature requests +------------------------------------ + +Bugs and feature request are tracked on [GitHub](https://github.com/Seldaek/monolog/issues) + +Frameworks Integration +---------------------- + +- Frameworks and libraries using [PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md) + can be used very easily with Monolog since it implements the interface. +- [Symfony2](http://symfony.com) comes out of the box with Monolog. +- [Silex](http://silex.sensiolabs.org/) comes out of the box with Monolog. +- [Laravel 4](http://laravel.com/) comes out of the box with Monolog. +- [PPI](http://www.ppi.io/) comes out of the box with Monolog. +- [CakePHP](http://cakephp.org/) is usable with Monolog via the [cakephp-monolog](https://github.com/jadb/cakephp-monolog) plugin. +- [Slim](http://www.slimframework.com/) is usable with Monolog via the [Slim-Monolog](https://github.com/Flynsarmy/Slim-Monolog) log writer. +- [XOOPS 2.6](http://xoops.org/) comes out of the box with Monolog. +- [Aura.Web_Project](https://github.com/auraphp/Aura.Web_Project) comes out of the box with Monolog. + +Author +------ + +Jordi Boggiano - -
