- 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.

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??
It's 12:01 a.m. and the sale goes live...

5. How can Applications Manager help?

6. Site is not reachable due to increased
traffic
Monitor site availability using
HTTP(s) URL Monitor and HTTP(s) URL
Sequence Monitor

7. HTTP(s) URL Monitor
• Average and Current
Response time
• Response time split-up:
• DNS Time
• Connection time
• First byte time
• Last byte time

8. HTTP(s) URL sequence - Transaction recorder

9. HTTP(s) URL Sequence Monitor

10. Landing page is slow
Monitor End User Experience using
Real Browser Monitoring

11. End User
Monitoring

12. Install agents in different locations (branch
offices or customer locations)

13. Real Browser Monitoring
• Mimics a user interaction
• Monitors your site periodically

14. Supported Real Browser Recording Agents

15. Recording a web script
• Launch the Real Browser
Recorder
• Enter the host and SSL port of
Applications Manager
• Enter the Applications Manager
credentials and proceed

End-to-end perspective of your Web Application

22. Apdex score
• Open standard
• Scale of 0 to 1
• Satisfied, Tolerating
and Frustrated users

23. Transaction - level metrics
• Response time
• Throughput
• Components split up

24. Traces - check which transaction took a long time

25. Traces - Summary of transaction with increased
response time

26. Trace details of the slow transaction

27. Use the Errors tab to analyse problematic code

28. JVM Metrics

29. Java Runtime Monitor

30. Triggering thread/heap dumps and performing
garbage collection through JRE monitor

31. See how your database is performing

32. See which transaction led to the slow query

33. Trace transactions down to the SQL query level

34. Monitoring Website ContentMonitoring Website Content
A few pages lead to a HTTP 502
bad gateway error
Monitoring Reverse Proxy (HAProxy)

35. HAProxy - HTTP Response Count

36. Monitoring Website Content
