ICounters class abstract

Interface for performance counters that measure execution metrics.

The performance counters measure how code is performing: how fast or slow, how many transactions performed, how many objects are stored, what was the latest transaction time and so on.

They are critical to monitor and improve performance, scalability and reliability of code in production.
