The Apache web server is at 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 a multi-tier model. In such architectures, the Apache web server plays a pivotal role since all users to the other tiers are routed via the web server and so any slowdown or problem in the web server tier adversely impacts the end user experience.
The availability of a web site and the response time for user accesses to the site are the most critical metrics of web performance. Both these metrics may vary depending from one website to another and even from one transaction to another. Today’s Apache monitor must be able to report the availability and response time for individual user transactions to a web site.
eG Enterprise adopts a unique two-pronged approach for web transaction monitoring. The external agent uses request emulation to assess the user experience from different locations. By doing so, the external agent captures the effect of the network latency and the server-side processing time on the end user experience.
To quantify the server processing times for real user requests (not emulated requests), the eG internal agent deploys a proprietary web-adapter technology. This technology enhances Apache web servers with the capability to track HTTP/HTTPS requests to a web server and the corresponding responses. For each transaction that is configured for monitoring, the web adapter analyzes the request URLs and responses to report various metrics relating to individual web transactions in real-time.
eG agents are able to monitor Java (Servlets, EJB, JSPs) and other non-Java implementations (ASP, PHP, CGI, etc.) as well. Since it is able to monitor real-user transactions to web servers in real-time, eG Enterprise can proactively monitor and quantify all anomalies that may occur in a web infrastructure.
The ability to offer real-time monitoring of 100% of the real user transactions, without the need for explicit, expensive logging is a key distinguishing feature of eG Enterprise's Apache monitoring capabilities. This one-of-a-kind monitoring capability supports other popular web servers as well.
