README

Adds a handler to monolog which can post your logs directly via discord webhook to your discord server channel.

Note

Discord has a character limit of 2000 (or 4000 when you have nitro). The message will get truncated when needed.

Installation

composer require thedomeffm/monolog-discord-handler-bundle

Configure the bundle

I've not added a recipe (or whatever I need to create 🤷), so you need to create the config by yourself.

# .env
DISCORD_WEBHOOK_URL="<your webhook url>"

Minimal

# config/packages/thedomeffm_monolog_discord_handler.yaml
thedomeffm_monolog_discord_handler:
    discord:
        webhook_url: "%env(DISCORD_WEBHOOK_URL)%"

Maximal

Note

Have in mind that json_pretty_print makes the message longer, and you'll reach the discord char limit easier!

# config/packages/thedomeffm_monolog_discord_handler.yaml
thedomeffm_monolog_discord_handler:
    discord:
        webhook_url: "%env(DISCORD_WEBHOOK_URL)%"

    formatting:
        characters_limit: 2000
        date_format: 'd.m.Y H:i:s'
        json_pretty_print: false

Configure monolog

Add the "service" handler

# monolog.yaml
monolog:
    handlers:
        # your other handlers...
        discord:
            type: service
            id: thedomeffm_monolog_discord_handler

Here is an example how a production config could look like:

# monolog.yaml
when@prod:
    monolog:
        handlers:
            main:
                type: fingers_crossed
                action_level: error
                handler: main_group
                excluded_http_codes: [404, 405]
                buffer_size: 50

            main_group:
                type: group
                members: ['error_stream', 'discord']

            error_stream:
                type: stream
                path: php://stderr
                level: debug
                formatter: monolog.formatter.json

            discord:
                type: service
                id: thedomeffm_monolog_discord_handler

            # your other handler...

Override the message content

Unhappy with my opinionated message design? Then decorate the factory. You can pass strings or the Text class into the Discord message.

// ...
use Monolog\LogRecord;
use Symfony\Component\DependencyInjection\Attribute\AsDecorator;
use TheDomeFfm\MonologDiscordHandlerBundle\Message\DiscordMessage;
use TheDomeFfm\MonologDiscordHandlerBundle\Message\DiscordMessageFactoryInterface;
use TheDomeFfm\MonologDiscordHandlerBundle\Message\Syntax;
use TheDomeFfm\MonologDiscordHandlerBundle\Message\Text;

#[AsDecorator(decorates: 'thedomeffm_monolog_discord_message_factory')]
class CustomMessageFactory implements DiscordMessageFactoryInterface
{
    public function createFromLogRecord(LogRecord $record): DiscordMessage
    {
        $message = new DiscordMessage();

        $message->append('# :x: Ohh noo an error!\n');
        $message->append(Text::create(Syntax::Code, $record->message)->render());

        return $message;
    }
}
