2 Quest Background Agenda Core Principles of Performance Understanding Production Environment issues Quest APM Approach Quest APM Solutions overview Demo

3 Company - Quest Software Company Size: $945 Million -- Market Capitalization Past 3 year Revenues: 2003 $304M 19% growth from $258M - 4.8% growth from $245M - 48% growth from 2000 Number of APM Customers: 18,000+ Number of Support Team Members: 220 Year Founded: 1985 Corporate Headquarters: Irvine, CA Number of Employees: Over 2,400

4 Core Principles Understand your goals of Performance Improve response time Improve throughput Ensure scalability Understand your application How does user activity affect each tier? Are there any hotspots? If so, why? i.e Is the application database-intensive? Understand there is no Silver Bullet Be objective Removing one bottleneck will often uncover another

5 Core Principles Take a System Approach Every layer and subsystem matters Apps Server Tuning Apps Server Test each change individually Document for future analysis

6 Core Principles Use more powerful machines Vertical scaling Best for CPU-intensive apps Use clustering Horizontal scaling Best in Web and application tiers Increases reliability Use network appliances Specialized hardware devices can increase performance Data storage devices, content caching engines & routers, load balancing hardware, SSL terminators

7 Production Environment Complexities Hardware Components Software Components

8 Common Bottlenecks >Firewall Devices 20 SSL handshakes/sec High CPU utilization Heavy I/O (eg. when logging) >Load Balancers Connection imbalance Low throughput >Web Servers Memory: excessive paging High Disk I/O Unbalanced server connections >Application Servers Memory: JVM paging DB connection contention CPU > 80% Execute queue waiting >Database Servers Cache hit ratio causes high disk I/O Memory: excessive paging and high I/O wait time High parse time

10 Quest s APM Application Suite for Performance J2EE Intro Management Suite for the J2EE platform An integrated solution that empowers all the stakeholders in J2EE application performance management to accelerate the detection, diagnosis and resolution of businessthreatening performance issues.

11 Key features of Quest s APM Solution Service Level management Improve staff efficiency by isolating performance problems based on service models and end user response time Application Server Diagnostics With very low overhead, quickly identify and resolve performance problems caused by resource bottlenecks and server configurations Deep Transactional Diagnostics Perform deep transaction-based diagnostics using Quest's Tag and Follow technology to identify renegade method or SQL causing performance problems Application code profiling Enable developers to quickly resolve the offending line of Java code necessary to improve end user response time

12 APM Suite: Breadth and Depth Application-level code assurance Certify applications before deployment 24x7 application performance management Find Memory Leaks Eliminate line-level bottlenecks Stop thread deadlocks Ensure performance and scalability under load Certify the application s SLAs Trending and capacity planning avoid future failures Real-time event management SLA reporting Problem detection, diagnosis & resolution

16 Quest APM -For every Stakeholder What code is behind the symptom? Is the application architecture a problem? Which SQL statements need tuning? Is the DB really the problem? What component is at fault? Who should fix the problem? Is the application available? Is the app server configured correctly?
