7. Agenda • Nature of Server Applications • Profiling Application Logs and Server • Profiling Performance Problems • Profiling Memory Problems • Load Testing
8. Server Applications • Applications Runs under IIS • Windows Services • Self-hosted Web Applications • Worker processes
9. Characteristics of Server Applications • Stateless • Multiple Instances • Concurrent • Spreaded and Connected • Multiple Versions at the Same Time

11. “Sometimes, you need all the connected process data to identify the problem.
12. Logging • Rich Logging • Application Logs • Server Logs • Storing the Logs (Elasticsearch) • Centralized Logging (Logstash) • Analysing the logs (Kibana) • Log correlation
