Digging In Facilities provided by MTS/COM+ and BizTalk How AppMetrics utilizes these facilities Metrics and Reports from AppMetrics for monitoring application state

Confluence of Trends MTS/COM+ Component- based Applications Need for Greater Scalability Distributed Applications

Problem with Scaling DCOM An object per client can’t scale Pooling of resources is needed to improve scalability

COM Interception is the Key Services JIT Activation JIT Activation Resource Pooling Resource Pooling System Metric Events System Metric EventsEvents Object Lifetime Method Calls Service Enlistment MTS/COM+

System Metric Events Examples ObjectCreate ObjectCreate ObjectRelease ObjectRelease ObjectActivate ObjectActivate ObjectDeactivate ObjectDeactivate MethodCall MethodCall Method Return Method Return More… More… Instance based Correlated externally Primary Key Foreign Key No correlation within MTS/COM+ Not ordered No guaranteed delivery Lots of them!

Event Correlation Events describe something that happened in the services infrastructure Events are associated by data in their event parameters Parameter data is optimized to reduce overhead during generation

AppMetrics Metrics Application/Package Process to Package mapping Process to Package mapping Alerts on process statistics Alerts on process statisticsComponents Organized by Class Organized by Class Durations Durations Counts Counts“Transactions” Logical Activities Cross Package/Process boundries

Putting the Data to Use Alerts Process Process Component Component Transaction TransactionReports Production Production Diagnostics Diagnostics Drill Down Drill Down

Early Warning Detection Alerts let you know when your application is getting into trouble Transactions or components take too long Transactions or components take too long Transactions abort Transactions abort Application crashes Application crashes Memory usage Memory usage Too many threads Too many threads

.NET and Beyond.NET Framework has components Enterprise Services is implemented with by COM+ services Minor “gotchas” to deal with System metrics events must be turned on System metrics events must be turned on Many run in the aspnet_wp.exe processes Many run in the aspnet_wp.exe processes Support in.NET Server 2003 and Everett needed for method detail

Why Monitor Application State? Improve Application Performance Minimize time spent troubleshooting Minimize time spent troubleshooting Eliminate downtime, outages & bottlenecks Eliminate downtime, outages & bottlenecks Eliminate “manual” monitoring Become proactive rather than reactive Become proactive rather than reactive Improve application control & uptime Improve application control & uptime Improve Service to customers & end users Proactive application management Proactive application management Meet & exceed application SLAs Meet & exceed application SLAs

Conclusion Having an accurate view of application state is a valuable addition to overall system monitoring Applications on the Microsoft platform expose application state through high volume events AppMetrics makes this data available to you
