Summary

This rule collects performance data for the Apache Virtual Host\ Errors per minute – client. The collected values are accessible in performance views and reports.

This metric exposes the average number of requests for the Apache Virtual Host that result in an HTTP client error status (400-499 status code) within a minute.

The value returned by the agent is calculated by dividing the increase in requests resulting in an HTTP client error status in a monitoring interval by the number of minutes in the interval.
