Add support for new handlers

[Seldaek]

Missing handlers:

• mongodb
• couchdb / doctrinecouchdb
• elasticsearch / elastica
• dynamodb
• syslogd
• loggly
• browserconsole (might need to be made the default in the standard edition if it works well)
• filter
• flowdock
• rollbar
• whatfailuregroup
• mandrill
• slack
• fleephook
• sampling

It looks like ChromePHP and Gelf support are now included, so I'd like to add support for the MongoDB handler, but I'm not sure of the best approach. Following the existing handler config would give something like:

<?php
// ..... snip ....

case 'mongodb':
    $definition->setArguments(array(
        new \Mongo($handler['host']),
        $handler['database'],
        $handler['collection'],
        $handler['level'],
        $handler['bubble'],
    ));
    break;

and allow a config like:

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        mongo:
            type: mongodb
            host: mongodb://localhost:27017
            database: logs
            collection: prod
            level: debug
            bubble: true

Creating the Mongo instance there is clearly not the correct way to do it, but I don't know the Service or DI layers well enough to know how to inject it correctly? Also, if I'm using Doctrine MongoDB ODM, it would be nice to be able to reuse the connection thats already been configured for that so that I don't have to maintain two separate configs.

Any ideas?

[Seldaek]

We could have an id: @foo.bar instead of host: mongodb://localhost:27017 (though that should also remain possible IMO if you only use mongo for logging). If it's provided you just use a new Reference($handler['id']) instead of that new Mongo.

You can look at the Gelf config for inspiration: https://github.com/symfony/MonologBundle/blob/master/DependencyInjection/MonologExtension.php#L133-148

@Seldaek I've tried to implement this as you described, however I end up with a circular reference.

The problem is that Doctrine\MongoDB\Connection only returns a \Mongo object after it has been initialised (with the method initialize and that at that point Doctrine requires a Monolog logger.

Any suggestions how this can be implemented?

[stof]

@florianeckerstorfer you have to use a mongo connection with logging disabled if you want to get it from the doctrine connection.

Is anyone working in mongodb handler?

[Seldaek]

I don't think so. I looked into it but it seemed non-trivial to wire up the doctrine mongo stuff etc so I gave up. If you'd like to give it a shot it would be much appreciated.

[pacoVela]

I'm wondering if doctrine is really necessary here. We can make the connection with a simple service, or directly with host/port/user/pass params. So you can use the same params for doctrine and monolog configurations, but it's only a matter of taste.

I agree with you that it is not trivial to do it with doctrine.

[wheelsandcogs]

My concern was duplicating the config if you were already using doctrine, and possibly the overhead of having another connection just for logging. Obviously it would be nicer to re-use the existing config and connection if possible, but I'd rather have a working mongodb handler with extra config than no handler at all.

[pacoVela]

Using params you don't have to repeat the literals for database host, and user... So you're true, the only caveat here is the overhead by the existence of another connection. In my case this is needed because we use a server just for logs.

[pacoVela]

I have the mongodb basic implementation ready to merge, (without doctrine stuff).

[kingcrunch]

It looks like the list in the initial description isn't up to date anymore?

[Seldaek]

@kingcrunch care to elaborate? I usually try to update it but maybe I missed one.

[kingcrunch]

@Seldaek I meant the list in this PR (above). I cannot edit that.

[Seldaek]

Yes I can update it but what is not up to date exactly?

[emgiezet]

I will add here the errbit / airbrake handler if its possible.

[Seldaek]

@emgiezet not sure what these have to do with monolog? Are there handlers out there somewhere that I don't know of?

[fotomerchant]

I've just submitted #92 for Slack support. Also submitted Seldaek/monolog#377 @Seldaek to add support to monolog SlackHandler for the emoji icons used by Slack.

Example conifg:

slack:
            type: slack
            token: xxxxxxx
            channel: C9342CD
            bot_name: YourBotName
            use_attachment: true
            icon_emoji: monkey_face
            level: error

Support for the WhatFailureGroupHandler is in #107.

Is there any way Rocket.Chat can be added to this list?

[PSF1]

I found a RocketChat Monolog handler that may simplify integration with Symfony: https://github.com/exileed/rocketchat-monolog by @exileed

[PSF1]

I'm working in a RocketChat integration pull request.

[PSF1]

Monolog project don't want add RocketChat support into main project: Seldaek/monolog#1310
Could monolog-bundle reference the @exileed's handler?

[stof]

Define a service for your handler and use the service type in the MonologBundle config

[PSF1]

This way? https://symfony.com/doc/current/logging/handlers.html

# config/packages/prod/monolog.yaml
monolog:
    handlers:
        es:
            type: service
            id: Symfony\Bridge\Monolog\Handler\ElasticsearchLogstashHandler

[stof]

yes, exactly.

[PSF1]

Thx so much :_ D

I have it working with less problems...

[Okhoshi]

Support for SamplingHandler is in #471
