ITCAM for Response Time – Overview


9

ITCAM for Response Time: Just Announced

“Customers are calling to complain about the response time for our online banking application”

ITCAM for Response Time alerts you to response time problems before customers call

ITCAM for Response Time supersedes the end user monitoring functions of ITCAM for Response Time Tracking

Solution

ValueITCAM for Response Time enables you to meet service level commitments by alerting you to problems before SLAs are violated and quickly isolating problems to minimize outages

Problem


10

Two Kinds of Response-Time Monitoring

Robotic Monitoring:Proactively find and correct problems before your users experience them!Both availability and response time monitoringReduce TTV by reusing existing and Mercury LoadRunner Rational scriptsSupports most applications with protocol-level, GUI, or command-line playback

Real-user Monitoring:Measure and report what real users are experiencingDemonstrate SLA compliance – robotic monitoring isn’t adequate for this!Isolate sporadic problemsWorks with browser and Windows application traffic

Capture robotic and real transactions from web apps and Windows clients

21

Real-User Monitoring for Web ApplicationsEnd-user performance and availability monitoring for web applications

Monitors network traffic for HTTP requests to the web server

Captures performance and availability data of actual users for SLA reporting


22

How Web Response Time Works

End user experience of Web-based applications performanceWeb request response time and its segmentationDifferent views of a same web request responsePerformance of web page request as well as each embedded object in that web pagePerformance of HTTP as well as HTTPS requestResponse time down to and including the workstation without actually being physically located on the workstation

The Web Response Time agent utilizes server-side monitoring to capture HTTP/HTTPS transaction data such as response time and status codes.


23

Web Response Time Algorithm


24

Web Response Time Capabilities

HTTP Monitoring of any web server or application server HTTPS Monitoring

IBM HTTP Server 6.0.x, 2.0.47+, 1.3Microsoft Internet Information Server 6.0Sun Java System Web Server 6.1Apache HTTP Server

Appliance ModeThe Analyzer can be configured to run on an appliance machine

Monitor Specific Network InterfaceMonitor a specific network interface on the system by default, the Analyzer monitors all network interfaces, however, you can limit the monitoring to one network interface


25

Real-User Monitoring for Windows Applications

Provides a true measure of the actual response time from the user’s perspective

Can monitor any Windows application

For supported applications, no special configuration needed to begin monitoring, just install and go.


26

Client Response Time Capabilities

Client Response Time agent measures and collects application response time on Windows clients from the end-user perspective

Gathers data for Windows clients from real end-users for SLA reporting

Virtually any Windows application can be monitored by creating custom behavior files with the ETEWatch Customizer

Out of the box support is provided for Lotus Notes, Microsoft Outlook, SAP GUI 6.X, PCOM, Exceed, Extra

Support for monitoring applications running on Citrix servers

Support for monitoring applications running on Terminal servers

Reports overall transaction response time as:Response Time = Network time + Application Time + Client Time


27

RT Reporting

ITCAM for RT reports on: Applications, Transactions, Clients and Servers.

Application – Represents the business process being monitored; for example, Lotus Notes, SAP, J2EE applicationsServer – Represents the machine that is running the applicationClient – Represents end user systems which access applications via transactions; for example, a location or organizationTransaction – A request against an application to perform some unit of work; for example, login, search, purchase (often identified by a URL)

28

RT Navigation

Create custom logical views and security roles to only view specific customer informationView the enterprise wide status

of all applications, clients and server. Easily understand SLA trends.

Quickly see the overall current status of each agent

Information regarding the performance of the web servers and their transactions.

Investigate issues directly on the agent


29

Configuring the RT Dashboard

RT provides the ability to define and configure custom high level dashboard views of Application, Transaction, Client and Server response time dataTransaction patterns allow you to define groupings of transactions that map to business applications and business transactions

For example, you can define a pattern *PlantsByWebSphere/login.jsp* and name the transaction “Login”and the application “PlantsByWebSphere”

Client patterns allow you to define groupings (based on IP & hostname) of your end users (or clients) by location, or functional unit

For example, you can define a client pattern for hostname *.austin.ibm.com and name the group “IBM Austin Internals”


30

RT Workspaces

For each monitored item per agent (i.e. application, transaction, server, client) RT offers the following workspaces:

Dashboard workspace: Introductory workspace offering a quick status of all monitored items and their percentage failure.

Availability workspace: Recent availability over time for a chosen item as well as the poorest performing areas of what it consists.

Trend workspace: Performance and volume over time for a chosen monitored item.

Top 5 Worst: The monitored items with the poorest availability, slowest response time, and the highest volume

Uptime/Downtime: Comparison of the monitored items up versus down time for a period of time as well as the number of incidents.


31
