Summary

This rule collects performance data for the Apache Virtual Host\ KB per Request performance counter. The collected values are accessible in performance views and reports.

This metric exposes the average amount of data (kilobytes) the Apache Virtual Host has transferred per request.

The value returned by the agent is calculated by dividing the increase in KB transferred in an interval by the number of requests in the interval.
