Ringkasan Tantangan

Report network IO statistics.

Instructions

Report network IO statistics.

You are writing a PaaS, and you need a way to bill customers based on network and filesystem usage.

Create a wrapper for network connections and files that can report IO statistics. The wrapper must report:

The total number of bytes read/written.
The total number of read/write operations.
