Save monolog in mongodb in symfony 4 - mongodb

Question

I want to add monolog in mongodb with default handler(MongoDBHandler) in Symfony 4.
my monolog.yaml file in dev folder
monolog:
handlers:
mongo:
type: mongo
mongo:
id: monolog.logger.mongo
host: '%env(MONGODB_URL)%'
database: '%env(MONGODB_DB)%'
collection: logs
my services.yaml
services:
monolog.logger.mongo:
class: Monolog\Handler\MongoDBHandler
arguments: ['#doctrine_mongodb']
my doctrine_mongodb.yaml
doctrine_mongodb:
auto_generate_proxy_classes: '%kernel.debug%'
auto_generate_hydrator_classes: '%kernel.debug%'
connections:
default:
server: '%env(MONGODB_URL)%'
options:
db: '%env(MONGODB_DB)%'
log:
server: '%env(MONGODB_URL)%'
options:
db: '%env(MONGODB_DB)%'
connect: true
default_database: '%env(MONGODB_DB)%'
document_managers:
log:
auto_mapping: false
logging: false
But doesn't work.
one of the errors:
Cannot autowire service "monolog.logger.mongo": argument "$database"
of method "Monolog\Handler\MongoDBHandler::__construct()" is
type-hinted "string", you should configure its value explicitly.
While i use database option in monolog config.
Is there any document?

Answer 1

Another way to enable mongodb for monolog is:
monolog:
handlers:
mongo:
type: mongo
mongo:
host: '%env(MONGODB_URL)%'
user: myuser
pass: mypass
database: '%env(MONGODB_DB)%'
collection: logs
, So it mean you need to remove id field and add user and pass instead.

If you use doctrine mongodb already, it's possible to re-use it's connection, avoiding more ENV vars to separate the DSN:
monolog:
handlers:
mongo:
type: mongo
mongo:
id: "doctrine_mongodb.odm.default_connection"
database: "%env(MONGODB_DB)%"
collection: MyLogDocument # Keeping this the same, allows you to simply use a doctrine repository to access the documents in your app if needed
level: debug

I get the following error:
Attempted to load class "MongoClient" from the global namespace.
Did you forget a "use" statement?
protected function getMonolog_Handler_MongoService()
{
$this->privates['monolog.handler.mongo'] = $instance = new \Monolog\Handler\MongoDBHandler(new \MongoClient('mongodb://admin:pass#localhost:27017'), 'monolog', 'logs', 100, true);
$instance->pushProcessor(($this->privates['monolog.processor.psr_log_message'] ?? ($this->privates['monolog.processor.psr_log_message'] = new \Monolog\Processor\PsrLogMessageProcessor())));
return $instance;
}
