Introduction to Web Server, tc Server & Hyperic

2. VFabric Suite Overview

3. VFabric Web Server
vFabric Web Server is the Web server and load-balancing component of VMware vFabric Cloud Application Platform
(vFabric Platform). vFabric Web Server 5.0 is based on Apache HTTP Server version 2.2.
In addition to the standard features of Apache HTTP Server, vFabric Web Server provides the following mission-critical
benefits:
 Ability to easily install multiple instances of vFabric Web Server running on a single computer.
 Scalable management of multiple Web sites and servers; you can run and manage hundreds of instances of
vFabric Web Server.
 Support for heterogeneous environments (32- and 64-bit architectures): Ubuntu, RHEL, and Microsoft Windows.
vFabric Web Server can be updated and patched across all servers at once. See Supported Platforms for
details.

Enterprise Capabilities

5. Standard Edition
● vFabric tc Server is a Web application server based on open-source Apache Tomcat.
● It preserves the best of Tomcat and adds many mission-critical operational capabilities that are unavailable in the
open-source product.
● With its lean architecture and small, 10MB memory footprint, tc Server requires significantly fewer resources
than conventional servers, which allows for greater server density in virtual and cloud environments.
● Pre-configured Templates
● Many instances from a single binary install
● Clustering
● JMX management enabled by default
● Latest security patches as binaries
● Integration with vFabric components

6. Troubleshooting An Application
● How many database calls does that page generate?
● What was the SQL executed?
● How long did the query take?
● Why does this page take a long time to load?
● Which part was slow?
● What happened then?!

7. Spring Insight to the Rescue
What does it provide?
• Information on all database queries
• Information on all web request and response information
• Lists component calls and parameters
Where can I use it?
• Agile Development
• QA
• Load Testing
• Production Monitoring
How does it work?
• Agent instruments application code using AspectJ
• Reports to “dashboard” (insight.war) component responsible for rendering statistics

12. tc Server Plug-In for Easier Management and Monitoring
The Hyperic tc Server plug-in enables you to remotely manage vFabric tc Server instances and applications on multiple computers. Hyperic
provides a single console with powerful dashboards through which you can:
 Manage the lifecycle of tc Runtime instances by starting, stopping, and restarting a local or remote instance.
 Manage the lifecycle of a group of tc Runtime instances that are distributed over a network of computers.
 Configure a single instance of tc Runtime. Configuration options include the various port numbers to which the tc
Runtime instance listens, JVM options such as heap size and enabling debugging, default server values for
JSPs and static content, JDBC datasources, various tc Runtime connectors, and so on.
 Deploy a Web application from an accessible file system, either local or remote. You can deploy to a single tc
Runtime instance or to a predefined group of servers.
 Manage the lifecycle of applications deployed to a single tc Runtime instance or group of servers. Application
lifecycle operations include start, stop, redeploy, undeploy, and reload.

13. Spring Insight Plugin
 Enables a Hyperic Agent running on a tc Server instance to auto-discover web applications
running on that instance and to obtain detailed, real-time application health and request metrics.
 Enables alerting on those metrics, as you can with other Hyperic resources and metrics. A new
interface view of application metrics associates the application to currently monitored Hyperic
resources such as application servers, database servers, the operating system, and specific
resource types
 By providing all of this information on one screen, Hyperic makes it easier to pinpoint whether
the problem is infrastructure- or application-related. If the application is the culprit, Hyperic-
Insight integration enables you to move from Hyperic to Insight, in the same application context,
to diagnose the underlying problem
