Git Clone Action Audit Event

I have an Ultimate Customer wants the ability to audit and log git cloning actions in order log the frequency of clones per user. They're also interested in receiving notification if the number of clones per user exceeds a specified threshold. They are currently unable to stand up an HTTP endpoint and therefore unable to track who is cloning specific repos and how often they are doing so. The main goal for the customer to having more visibility into which developers are cloning repos and making sure they do not have too many duplicates.
