Monolog Sentry Handler

It is a Monolog handler for Sentry PHP SDK v2, v3 and v4 with breadcrumbs support.

Features

• Send each log record to a Sentry server
• Send log records as breadcrumbs when they are handled in batch; the main reported log record is the one with the highest log level
• Send log along with exception when one is set in the main log record context
• Customize data sent to Sentry to fit your needs
• Compatible with Monolog 1, 2 and 3

Installation

The suggested installation method is via composer:

# For Sentry PHP SDK v3/v4
composer require bgalati/monolog-sentry-handler

# For Sentry PHP SDK v2
composer require bgalati/monolog-sentry-handler:^1.2

Basic usage

<?php

use BGalati\MonologSentryHandler\SentryHandler;
use Sentry\State\Hub;

$sentryHandler = new SentryHandler(Hub::getCurrent());

/** @var $logger Monolog\Logger */
$logger->pushHandler($sentryHandler);

// Add records to the log
$logger->debug('Foo');
$logger->error('Bar');

Check out the handler constructor to know how to control the minimum logging level and bubbling.

Note

• It is a good idea to combine this handler with a FingersCrossedHandler and a BufferHandler to leverage Sentry breadcrumbs. It gives maximum context for each Sentry event.

Look at the symfony guide for a complete example with Monolog and symfony

FAQ

What are the differences with the official Monolog Sentry handlers?

At the moment the official SDK proposes two Monolog handlers:

• Sentry\Monolog\Handler: each logs becomes a Sentry event
  • Depending on the setup it can create a lot of noise.
• Sentry\Monolog\BreadcrumbHandler: each logs is added as a breadcrumb in the current event
  • It cannot be used only with Monolog: it requires default integrations to work correctly.

Both of them don't send event immediately. Thus, sending Sentry events happens; either when PHP process terminates or when the flush is done explicitly.

This lib proposes a Handler that is different:

• It flushes Sentry events on each call: looks like a standard for Monolog handlers
• It adds log records as breadcrumbs when it is used with a buffering handler like FingersCrossedHandler

What about contributing it to the Monolog project?

As per this comment, Monolog project does not accept new handler with 3rd party dependencies.

For new handlers with third-party dependencies IMO the right way is to publish as a third-party package, with requires on monolog and on whichever dependency is needed. It lets Composer resolve everything which makes more sense really.
