© 2011 IBM Corporation IBM Corporation03/14/11 29 Tivoli Enterprise Portal (TEP) … ITCAM for Application Diagnostics Integrates with ITCAM for Transaction Tracking Viewing Transaction Flow from TEP With ITCAM for WAS/J2EE and TTAPI integration, Users can use the following ITCAM for Transaction Tracking workspaces to view the transaction flow: ● Servers: This workspace provides aggregated data for all transactions and requests that occur in a physical computer over a period of time called the Aggregation Period. Transactions and requests can come from WebSphere Application Server, Web Servers, and WebSphere MQ products. The workspace is mainly used to isolate a performance problem to a physical computer. ● Components: This workspace provides aggregated data for all transactions and requests that occur in a major software component over a period of time. The main software components in a WebSphere production system may include WebSphere Application Server, WebSphere MQ, Web Server, and so on. Data reported by this workspace is mainly used to isolate a performance problem to a software component. ● Applications: This workspace provides aggregated data for all transactions and requests that occur in a major runtime instance within a period of time. For example, for the WebSphere Application Server component, the runtime instance is a WebSphere Application Server process; for WebSphere MQ, it is a queue manager process. The workspace is mainly used to isolate a performance problem to a runtime instance. ● Transactions: This workspace provides aggregated data for transaction instances. The aggregation is done over each distinctive Unit of Work (UOW) or Request. For example, in a WebSphere Application Server environment, a transaction or UOW is usually identified as a URI for a Servlet or JSP page. Data reported by this workspace can be used to isolate a performance problem to a specific transaction or request.

© 2011 IBM Corporation IBM Corporation03/14/11 33 MSVE - Availability ● Enterprise Overview displays information for all groups of servers. ● Group Overview provides a high-level overview of activity for each server in the group. The overview includes the response time and throughput for the last hour as well as the current monitoring level for each server. ● Server Overview displays comprehensive server information, activity and statistics for the selected server. ● Server Statistics Overview helps you compare activity and related platform data across servers so that you can recognize problems. ● Recent Activity Display helps you investigate potential memory problems relating to garbage collection and the JVM heap size. ● System Resources displays summary information for all resources on the selected application server. ITCAM captures the data for this page every five minutes for display. ● SMF Data View detailed information on Server, EJBs, Servlet Session Manager, Web applications, and Server Regions. The source of the data comes from the SMF records published by WebSphere on z/OS. The Application Monitor intercepts the transfer of the records and makes a copy in real time before writing it to the SMF dataset.

© 2011 IBM Corporation IBM Corporation03/14/11 39 MSVE - Problem Determination ● Alerts and Events Monitors high-priority trap alerts and Tivoli Enterprise Portal (TEP) events for the last 24 hours. From here, you can escalate events into the Problem Center for diagnosis and tracking. ● Problem Center All problems are escalated high-priority trap alerts and Tivoli Enterprise Portal (TEP) events. The details of each problem are available for your review. ● In-Flight Request Search lets you search for a request on your application servers by entering search data such as a URL. You may also view the stack trace, component trace, or method trace for a particular request. View, e-mail, or export the PDF file of the trace to other ITCAM users. ● Server Activity Display (SAD) provides thread data for an application server at a specific point in time, lock contention, or the 100 most recently completed requests. You may filter the threads by the type or thread status. After pinpointing a hung thread, click the Thread ID link to review its request detail. Click links to view the stack trace, component trace, or method trace. View, e-mail, or export the PDF file of the trace to other ITCAM users. ● Web Session Browser retrieves information on HTTP sessions. You can search a server, a group, or all servers and groups for a specific session. After activating the search, the system will take a snapshot of the server(s) and return a list of sessions.

© 2011 IBM Corporation IBM Corporation03/14/11 40 MSVE - Problem Determination … ● Memory Diagnosis The Memory Diagnosis section helps you discover memory related problems. Memory Analysis lets you create server activity analysis reports regarding memory. Heap Analysis captures the runtime heap of an application server and breaks it down by the class names of the objects residing in the heap at the time of the snapshot while providing the number of instances and the size of the information. Lastly, Memory Leak helps confirm the existence of a memory leak and identifies the most likely memory leak candidates. The Heap Dump Management provides a list of all the previously taken heap dumps. ● JVM Thread Display The JVM Thread Display shows all the threads running on the JVM, organized within thread groups. In addition, the JVM Thread Display provides a Thread Dump so you can view detailed information about resource consumption in a JVM. In addition, you can click on a thread to view the details for the thread, or to view a stack trace, change the thread priority, or cancel a thread. ● Trap and Alert Management Set software traps and alerts to monitor a group of servers or a selected server. Notifications are sent immediately when the system meets the conditions of the trap. Actions include sending an e-mail or an SNMP message, collecting Stack Trace, Component Trace, Method Trace, or Thread Dump. ● Software Consistency Check Use the software consistency check to troubleshoot atypical servers in an otherwise homogenous server group.
