500 Error Logs from WP

Hi,

This is regarding our blog (blog.kolabtree.com), which uses a WP SmartMag theme and is being hosted on Azure. We’ve found that the blog shows a 500 error on and off (three times so far in Jan 2017). The blog worked normally after we restarted the server. I was wondering if there is a way we could get the error logs from WordPress to understand what had happened?

TIA!
