The Tomcat server is a Java based Web Application container that was created to run Servlets and JavaServer Pages (JSP) in Web applications. As part of Apache's open source Jakarta project, it has nearly become the industry accepted standard reference implementation for both the Servlets and JSP API.
Application developers capitalize on the capabilities of the Tomcat container to build robust web applications that provide mission-critical services to end users. Naturally, the 24 x 7 availability and speedy responsiveness of the Tomcat server is imperative for the applications and the dependent businesses to remain afloat.
The application server middleware that hosts and supports the business logic components is often the most complex of the multi-tier infrastructure. To offer peak performance, an application server provides a host of complex functions and features including database connection pooling, thread pooling, database result caching, session management, bean caching and management etc. To ensure that the application server is functioning effectively at all times, all of these functions have to be monitored and tracked proactively and constantly.
eG Enterprise offers specialized monitoring models for each of the most popular application servers such as WebLogic, WebSphere, ColdFusion, Oracle 9i/10G, etc. A plethora of metrics relating to the health of the application servers can be monitored in real-time and alerts can be generated based on user-defined thresholds or auto-computed baselines. These metrics enable administrators to quickly and accurately determine server availability and responsiveness, resource usage at the host-level and at the application server level, how well the application server processes requests, how quickly the server completes transactions, overall server security, etc.
