[Monolog] Handler not including context

[apapsch]

We have many log calls that are structured in the suggested way, i.e. context is an array with arbitrary fields:

                    $this->logger->error('Could not find channel of order', [
                        'order_id' => $orderId,
                        'channel_id' => $channelId,
                    ]);

Up until this week, we were still using Sentry 1.10 and the deprecated handler from Monolog upstream. The handler was configured with a LineFormatter and the line format %message% %context% %extra%. Sentry received messages like:

Could not find channel of order {"order_id": "FOO-1", "channel_id": "42"} []

Now we upgraded to Sentry 2.x and switched to the Sentry\Monolog\Handler. The message is now:

Could not find channel of order

The context is missing and also cannot be found under "Additional Data". Looking in the source of the integrated handler, the reasons become clear:

• l. 49: The Sentry field message ist set using the Monolog field message, which ignores the formatted field set by the LineFormatter.
• The arbitary context fields are not set in the Sentry scope.

The old behavior with the context added to the message as JSON object was not ideal, because Sentry would have had a hard time automatically merging the issues, resulting in many separate issues that needed manual merging. Therefore I would send a PR that adds the arbitrary context fields to the Sentry scope via setExtra.

This has already been discussed in #848 and #844 and reasons have been explained about why we won't support anymore out-of-the-box blindly setting what is in the context and/or in the extra field in the event. There is a package developed by @B-Galati that can help you by restoring pretty much what was done in 1.x.

Good stuff, I will check it out. Closing then.

seems like this feature is supported now.

in symfony sentry bundle with following config worked:

monolog:
    handlers:
        sentry:
            type: sentry
            dsn: "%env(SENTRY_DSN)%"
            level: !php/const Monolog\Logger::ERROR
            fill_extra_context: true #<- monolog data can be logged with this flag

for more info you can check Sentry\Monolog\Handler
