README

A collection of configurable logging adapters with logging functionality loosely PSR compatible for phalcon 3.x and PHP 7.x. Currently the following adapters are implemented:

Sentry

Depends on the sentry/sentry package.
You have to run composer require sentry/sentry
You might have to require Raven_Autoloader as explained here (see #installation section below)
Disabled by default but is active if class Raven_Client is defined.

Slack

Self contained and ready to work out of the box.

... and we plan to add a few more!

Installation

It is a fully composer ready library. Just run:

$ composer require crazyfactory/phalcon-loggers

If you have not used composer's autoloading (i.e. require 'vendor/autoload.php') &/or just want to use phalcon's native autoloader:

$loader = new Phalcon\Loader;
$loader->registerNamespaces([
    'CrazyFactory\\PhalconLogger' => '/path/to/vendor/crazyfactory/phalcon-loggers/src/',
])->register();

If you want to use Sentry as well:

$ composer require sentry/sentry

If you have not used composer's autoloading, then setup autoloading of Raven_ classes like so:

require_once '/path/to/vendor/sentry/sentry/lib/Raven/Autoloader.php';
Raven_Autoloader::register();

Usage

The easiest and quickest way to use this library is by using the supplied Service:

$id = (new Phalcon\Security\Random)->uuid();
$di = new Phalcon\Di\FactoryDefault;
(new CrazyFactory\PhalconLogger\Service)->register(null, $di);

// If you already have `requestId` in config array/object you don't need to set it again.
$di->getShared('logger')->setRequestId($id);

$di->getShared('logger')->info('some text');
// Supports interpolation for keys wrapped in curly brace.
$di->getShared('logger')->critical('some text {key}', ['key' => 'val']);

//
// Below examples assume that info level is allowed in config->slack->levels array.
//
// Mention an user in slack:
$context = ['mentions' => 'slackbot', 'a' => 10];
$di->getShared('slack')->info('some text {a}', $context);

// Customize channel, username, icon_emoji, icon_url via context:
$context += [
    'username' => 'bot',
    'channel' => '#general',
    'icon_emoji' => ':monkey_face:',
];
$di->getShared('slack')->info('some other text {a}', $context);

// Attachment:
$context += [
    'attachment' => [
        'title' => 'Attachment title',
        'text' => 'Attachment text',
        'color' => 'good',
    ],
];
$di->getShared('slack')->info('yet other text {a} with attachment', $context);

See examples for details and various integration samples. Also see the API section.

Configuration

You can pass in configuration as an array or a file The loggers have their own configuration options but share common parameter requestId and environment. Here is how a typical configuration looks like for slack and sentry both:

use Phalcon\Logger;

$config = [
    // The application name used in logs. Helps to distinguish &/or search.
    'appName' => '',
    // Current application environment.
    'environment' => 'prod',
    'requestID'   => null,
    'sentry'      => [
        // The login information for Sentry. If one of the values is empty the logging is suppressed silently.
        'credential' => [
            'key'       => '',
            'secret'    => '',
            'projectId' => '',
        ],
        // The options for Raven_Client. See https://docs.sentry.io/clients/php/config/#available-settings
        'options' => [
            'curl_method' => 'sync',
            'prefixes'    => [],
            'app_path'    => '',
            'timeout'     => 2,
        ],
        // Sentry will log errors/exceptions when the application environment set above is one of these.
        'environments' => ['prod', 'staging'],
        // The log levels which are forwarded to sentry.
        'levels' => [Logger::EMERGENCY, Logger::CRITICAL, Logger::ERROR],
        // These exceptions are not reported to sentry.
        'dontReport' => [],
    ],
    'slack' => [
        // If webhook url is missing the logging is suppressed silently.
        'webhookUrl'   => '',
        // Slack will log messages when the application environment set above is one of these.
        'environments' => ['prod', 'dev'],
        // Curl method can be 'sync' or 'exec' (sync uses php curl_*, exec runs in background).
        'curlMethod'   => 'sync',
        // HTTP headers to be appended to request.
        'headers'      => [],
        // The log levels which are forwarded to slack.
        'levels'       => [Logger::SPECIAL, Logger::CUSTOM],
    ],
];

$di = new Phalcon\Di\FactoryDefault;

// Register the loggers with the config:
$di->setShared('sentry', function () use ($config) {
    return new CrazyFactory\PhalconLogger\Adapter\Sentry($config);
});
$di->setShared('slack', function () use ($config) {
    return new CrazyFactory\PhalconLogger\Adapter\Slack($config);
});

// OR you could just use supplied `Service`:
(new CrazyFactory\PhalconLogger\Service)->register($config, $di);

API

All the loggers inherit from base phalcon logger adapter so they automatically inherit public callable APIs from the base. In addition the loggers may also expose some APIs available for direct call.

Sentry:

Sentry logger has following public APIs:

addCrumb(string $message, string $category = 'default', array $data = [], int $type = null)

    $di->getShared('sentry')->addCrumb('User has just logged in');

setTag(string $key, string $value)

    $di->getShared('sentry')->setTag('name', 'value')->setTag('another', 'another-value');

setUserContext(array $context)

    // you can also use current user from DI if you have one
    $di->getShared('sentry')->setUserContext(['id' => 1, 'username' => 'someone', 'email' => 'bob@example.com']);

setExtraContext(array $context)

    $di->getShared('sentry')->setExtraContext(['arbitrary_key' => 'arbitrary_value', 'arbitrary_key_2', 'arbitrary_value_2']);

getLastEventId()

    $di->getShared('sentry')->getLastEventId();

logException(\Throwable $exception, array $context = [], int $type = null)

    try {
        $app->handle();
    } catch (\Throwable $e) {
        $di->getShared('sentry')->logException($e);
        // However it is advisable to just use logException of the logger collection
        // so that all the registered loggers are notified of the exception to do the needful.
        $di->getShared('logger')->logException($e);
    }
