The ApacheMonitor ZenPack provides a method for pulling performance metrics from the Apache Web server directly into Resource Manager, without requiring the use of an agent. This is accomplished by using Apache's
mod_status module that comes with Apache Version 1 and 2.
The following metrics are collected and graphed for the Apache HTTP server.
Requests per Second
Throughput (Bytes/sec and Bytes/request)
CPU Utilization of the HTTP server and all worker processes or threads
Slot Usage (Open, Waiting, Reading Request, Sending Reply, Keep-Alive DNS Lookup, and Logging)
