### Description

#### What problem are you trying to solve?
I want to be able to export all the logs coming to my instance to graylog or a syslog server.

#### Proposed solution
I tried to search on the internet and didn't find anything.

Could you please add this feature on next release that we can use to export all logs to a remote server or a graylog?

Thank you.

Regards.
