 Yes, good catch.

 You're also not exporting the data, it's mostly a consideration in the
 case that the machine or service is compromised. I don't see issues with
 an attacker getting ahold of the number of requests made and the times at
 which they are made. There are probably easier ways to find out whatever
 information they would hope to find out from these logs anyway.

 Yes, agreed.

 Ok, I'll move forward with setting up the service on polyanthum. Thanks
 for the reviews!
