## Documentation
|
||||
|
||||
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.
|
||||
- [Usage Instructions](doc/01-usage.md)
|
||||
- [Handlers, Formatters and Processors](doc/02-handlers-formatters-processors.md)
|
||||
- [Utility classes](doc/03-utilities.md)
|
||||
- [Extending Monolog](doc/04-extending.md)
|
||||
|
||||
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
|
||||
====
|
||||
|
||||

||||
|
||||
- _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.
|
||||

|
||||
- _ErrorLogHandler_: Logs records to PHP's
|
||||
[`error_log()`](http://docs.php.net/manual/en/function.error-log.php) function.

||||
### 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.
|
||||
- _PHPConsoleHandler_: Handler for [PHP Console](https://chrome.google.com/webstore/detail/php-console/nfhmhhlpfleoednkpnnnkolmclajemef), providing
|
||||
inline `console` and notification popup messages within Chrome.
|
||||
|
||||
### 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.
|
||||

|
||||
- _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.

## Installation
|
||||
|
||||
Monolog is available on Packagist ([monolog/monolog](http://packagist.org/packages/monolog/monolog))
|
||||
and as such installable via [Composer](http://getcomposer.org/).
|
||||
|
||||
```bash
|
||||
php composer.phar require monolog/monolog
|
||||
composer require monolog/monolog
|
||||
```
|
||||
|
||||
If you do not use Composer, you can grab the code from GitHub, and use any
|
||||
PSR-0 compatible autoloader (e.g. the [Symfony2 ClassLoader component](https://github.com/symfony/ClassLoader))
|
||||
to load Monolog classes.

Configuring a logger

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

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.
|

|
||||
- _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

|
||||
|
||||
## 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.
|
||||

# Third Party Packages
|
||||
|
||||
Third party handlers, formatters and processors are
|
||||
[listed in the wiki](https://github.com/Seldaek/monolog/wiki/Third-Party-Packages). You
|
||||
can also add your own there if you publish one.

# 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.

You can use a `unix://` prefix to access unix sockets and `udp://` to open UDP sockets instead of the default TCP.
