ITCAM for Websphere/J2EE
 ITCAM for WR provides a more affordable and less complex J2EE application
monitoring solution for IT Operations who want:
 To quickly identify, isolate problems and route to the appropriate SME.
 Resource monitoring to be proactive in problem identification and eliminate the need
for cross-SME teams to resolve issues.
 To centralize monitoring and reduce reliance on SMEs.
 ITCAM for WR provides resource and application monitoring with the Tivoli
Enterprise Portal (TEP) user interface.
 ITCAM for WR has easy out of the box installation - installs and deploys in a few
hours!
 ITCAM for WR has improved operations dashboards with needed data to quickly
identify the source of the problem.

ITCAM for Web Resources – New Feature Overview
 Simplified Installation
–Installation launch pad for all supported resources and silent install of infrastructure (TEP/DB2)
 Auto Learning of Thresholds
–Used to benchmark performance for a new application (or a changed environment) to understand where
thresholds should be established
 Application dashboard
–Summary view of applications to give operators and administrators, at a glance, the ability to see where the
problem is located (client tier, application tier or backend tier). These out of the box views are per
application server; however, logical views can be customized to include two or more application servers, and
can be customized to include a view of the entire application stack, to include databases, web servers and
OS resources.
 Java Standard Edition (J2SE) Workspaces
–monitors stand alone java applications
 Best practices documentation for logical views (Delivered via OPAL)
–Logical views allow disparate resources to be grouped together
–Resources can be viewed by geographic, functional, or relationship-based groups.
–Scalable background images/bitmaps
 Situation Scripting:
– Predefined situations that include preset thresholds, sampling intervals, boolean logic, and expert advice
(Delivered via OPAL)
–Creation of new situations available for customers to correlate any related data that will alert operations to
a potential problem. For example:
Correlate average response time alerts with an increase in CPU usage, to alert operations to a
possible memory leak.
Correlate growth in HTTP sessions with an increase in average response time to an increase in JVM
memory usage. Alert operations to check timeout sessions for HTTP sessions

Request Analysis
 Operations teams track the average response time for requests processed on the app
server, and can quickly detect issues when delays increase over time or spike. This
workspace shows the worst average response times broken down by Java Component

Pool Analysis
 J2EE resource pools are critical in terms of providing availability to commonly accessed
services such as database access and other container pool types. This workspace
enhances PMI data with configuration data to provide a comprehensive overview of
requests flowing through WebSphere “funnel”.

Garbage Collection Analysis
 Garbage Collection (GC) metrics such as frequency and time to complete can have a large
effect on application server performance (during this time no other application processing
can take place). This workspace shows a detailed breakdown of GC behavior and provides
an complete analysis of GC performance metrics.

 Examples of situation
correlation include:
–
Correlate average response time
alerts with and increase in CPU
usage, to alert operators to
investigate a a memory leak.
–
Correlate alerts for increased
activity on the server to ensure
JVM memory usage is not
impacted. Correlate growth in
HTTP sessions with an increase
in average response time to an
increase in JVM memory usage.
Alert to check timeout sessions
for HTTP sessions set to

Current State Of IT Application Management
IT organizations are under tremendous pressure to deliver results.
IT Challenge
Business Impact
Majority of IT problems are still being
identified by end user complaints
Lost business when problems go
undetected; impacts customer
satisfaction
Composite application performance
problems can take many hours to isolate
Support budget spent isolating problems
instead of fixing them
Once problem is identified a large team of
specialists is required to resolve the
problem
Large amount of money from both
development and support spent solving
problems
Most application problems go back to
development group, which cannot recreate
the problem
Development budget spent fixing problems
instead of building new applications
… What we need is comprehensive application management

End User Monitoring is the Best Way to Determine what IT
Problems need Attention
What is the Customer
Experience?...
Web server thread pools
are full - is it impacting
the customer response
time?
… Do you know what your customers are experiencing? Or are they calling your help
desk to tell you that you have an availability or response time problem. Effective
application management requires monitoring both application resources and response
times to find the real problems that are impacting your business
