What is domainlog?

Domain logs provide several logical views of domain-level activities involving packages, MBOs, users, devices, operations, and subscriptions. Domain administrators use this data to monitor and troubleshoot activity within an individual domain. However, only a platform administrator can configure domain log properties. The domain logging option must be enabled on the domain or for package-level logging to start.

Path to domlogs:
/usr/local/apache/domlogs/

How to find domain log for particular domain?

sudo tail -f domain-name.com | awk ‘{print $1, $2}’ OR sudo tail -f addon.domain-name.com | awk ‘{print $1, $2}’
