1. About

The ApacheMonitor ZenPack provides a method for pulling performance metrics from the Apache Web server directly into Zenoss, 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)
