- The document discusses how Applications Manager can help optimize application performance for an e-commerce site experiencing issues during a flash sale, including slow page loads, errors, and site unavailability. - It describes how Applications Manager can monitor site availability, end user experience, web application performance, reverse proxies, and detect website defacement using tools like HTTP monitors, real browser monitoring, APM Insight, JVM monitoring, and website content monitoring. - The goal is to provide visibility into the user journey, transaction performance, errors, and system components to troubleshoot and optimize the application.
Optimize application performance - Mumbai Seminar
- 1. How DevOps can optimize application performance with Applications Manager
- 2. • Synthetic transactions to capture end user interactions • Monitoring the complete end user journey • Debugging transaction performance problems • Monitoring web service components • Troubleshooting common application performance issues • Detecting website defacement Agenda
- 3. A flash sale on an e-commerce site
- 4. • Site not reachable. Too many people accessing it at once. • Landing page is slow • Clicking on Mobiles and Tablets category leads to HTTP 500 internal server error • Some pages lead to a HTTP 502 bad gateway error • Did you click on the Electronics category??
