Introduction

Apache Web Server is a web server based on the Apache Software Foundation's Apache HTTP Server that runs on AIX, HP-UX, Linux, Solaris, Windows NT, and z/OS. The web servers are the heart of IT infrastructures in various domains - Healthcare, Banking, Trading, Logistics, etc. To ensure scalability and high performance, most web sites are being architected to use the multi-tier model - i.e., with the web server (IIS, Apache, etc.) functioning as the front-end, the middleware application server (J2EE, .Net based, etc.) that hosts the business logic functioning as the mid-tier, and a database server (SQL, Oracle, etc.) as the backend. In such architectures, the web server plays a pivotal role since all users to the other tiers are routed via the web server and hence, any slowdown or problem in the web server tier can adversely impact the end user experience.

To ensure the uninterrupted operations of the Apache web server, administrator should continuously track overall health indicators such as the availability of the web server, the data processing ability of the server, the data traffic handled by the server, etc. To cater to the requirements of such administrators, eG Enterprise provides a specialized Apache Web server model. The statistics reported by this model, enable administrators to find out accurate answers to server's health related queries.
