How to see inside $this object in Magento 2 logger

Question

How can I see inside the $this object in my logger file using prs logger?

I tried this

\Magento\Framework\App\ObjectManager::getInstance()->get(\Psr\Log\LoggerInterface::class)->info("in getMediaGalleryImages " .json_encode($this));

But this gives me {} every time.

[2019-05-29 10:07:24] report.INFO: in getMediaGalleryImages {} [] []

What's the right method to see inside the $this object in Magento 2 logger.

Answer 1

1. Use DependencyInjection instead of ObjectManager
2. 2nd argument of any Logger message is Context - use it instead. Example:

$this->logger->warning('User cannot be logged in', ['username' => $user, 'ip' => $ip]);

3. Use $this->getData() instead of just $this
