Analytics tool to count I/O

Hi CUBA team,
In cuba platform is there any tool available to get I/O count…like firebase, google analytical tool …How we can get total number of I/O hits done in application using cuba framework…can you give solution for that…?
For example,
If we sent an api to hit the server means how many inputs(request) and outputs(response) is performed by the API that count we need.How we can implement in CUBA?
