Information Disclosure of Garbage Collection Cycle

How it was found

Hello,

Upon enumerating a subdomain content I found a directory that discloses the duration of the garbage collection cycles. I think that these information should be kept private because public should not know information about the target application and how it operates or do its garbage collection process.

Steps To Reproduce

1. Navigate to the target url: https://gopher.hey.com/metrics
2. See the data.

███

Impact

This information may help attackers understand more things about the target application which may help in further investigation and exploitation.

Kind Regards.
