How to see full log detail not truncated

I am lost here. I use Amazon SES for mail. Logged in to bash in the container, I don’t know where to find Discourse logs for mail. I am unable to see anything relevant in /var/log. Apologies for being a complete ignoramus. I was at least able to see the logs at the /logs URL for Discourse, but why cant I find this on disk. Are they in a database?
