I have a deployment with some gateways that log to their management where logs get stored for x months. A new gateway on a remote site brings a regulatory requirement to keep logfiles back for 7 days at most, after that time logs have to be purged.
Is there any other way to comply with this requirement other than using a separate/dedicated log server for this gateway, like a secret fw log command that can delete entries from a specific object in the log?

I'm pretty sure there is no way to do this but if there is a way to not have a separate log server it would help tremendously.
