Ability to view and track collection wise transactions (read,write,success,failures)

We have multiple microservices using the same collection and we'd like to track how many calls come from each, and also understand which transactions are successful or not. Ultimately this will allow us to understand the MDB usage by each of the microservices. [setting verbose logging level to 1 and then using these logs to create a dashboard in Splunk doesn't give us enough granularity]
