Third review presentation

  1. 1. Design and Implementation of a ServiceMonitoring Console within a Service Oriented Architecture Framework Arvind Krishnaa .J 31508104017 Guided By Dr. Chitra Babu HOD/CSE SSN College of Engineering Third Review - 04th April, 2012
  2. 2. Ebay’s SOA Framework 1 Client Runtime - Client application code written by the consumers of the service. Service Invocation Framework(SIF)
  3. 3. Ebay’s SOA Framework 1 Client Runtime - Client application code written by the consumers of the service. Service Invocation Framework(SIF) 2 Server Runtime - Deployment platform for developers to publish web services. Service Provider Framework (SPF)
  4. 4. Ebay’s SOA Framework 1 Client Runtime - Client application code written by the consumers of the service. Service Invocation Framework(SIF) 2 Server Runtime - Deployment platform for developers to publish web services. Service Provider Framework (SPF) 3 CodeGen - Generate boiler-plate code for deploying services as well as their consumers.
  5. 5. Architecture of the SOA framework Figure 1: Architecture of the SOA framework
  6. 6. Where does services monitoring fit in? 1 Develop a service or a consumer to a service using the Eclipse SOA plugin
  7. 7. Where does services monitoring fit in? 1 Develop a service or a consumer to a service using the Eclipse SOA plugin 2 Deploy the service on an application server
  8. 8. Where does services monitoring fit in? 1 Develop a service or a consumer to a service using the Eclipse SOA plugin 2 Deploy the service on an application server 3 The service logs the metrics onto the Central Application Logging Framework
  9. 9. Where does services monitoring fit in? 1 Develop a service or a consumer to a service using the Eclipse SOA plugin 2 Deploy the service on an application server 3 The service logs the metrics onto the Central Application Logging Framework 4 CAL - an aggregator for critical metrics, acting as the focal point for generating custom reports
  10. 10. SOA Metrics Dashboard (SMC) Figure 2: Overview of SOA Metrics Dashboard
  11. 11. Metrics collection in SMC
  12. 12. Issues in SMC 1 Outdated V4 technology for constructing the GUI 2 Very slow! 3 Code is highly monolithic with several metric parameters hard-wired into the code 4 Difficult to develop further, as well as difficult to move it to a more efficient mechanism
  13. 13. Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner
  14. 14. Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner 2 Fast response time of the UI layer
  15. 15. Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner 2 Fast response time of the UI layer 3 UI design using a scalable framework
  16. 16. Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner 2 Fast response time of the UI layer 3 UI design using a scalable framework 4 Ability to handle large number of services
  17. 17. Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner 2 Fast response time of the UI layer 3 UI design using a scalable framework 4 Ability to handle large number of services 5 Continuous availability of the service
  18. 18. Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner 2 Fast response time of the UI layer 3 UI design using a scalable framework 4 Ability to handle large number of services 5 Continuous availability of the service 6 Real-time metrics gathering

Design goals for the services dashboard 1 Monitoring metrics of services in a modular and loosely coupled-manner 2 Fast response time of the UI layer 3 UI design using a scalable framework 4 Ability to handle large number of services 5 Continuous availability of the service 6 Real-time metrics gathering 7 Extensibility over exhaustive features
  20. 20. What is Turmeric? What is TMC? Turmeric: Part of the eBay SOA framework is open-sourced, and this environment is called Turmeric Services and consumers can be created uing the open-source plugin Define type libraries, error libraries for re-use across applications Turmeric Monitoring Console: The open-source equivalent of SMC
  21. 21. Architecture of the Monitoring Console 1 Can be abstracted to two frameworks running in parallel - metrics logging framework and metrics handler framework
  22. 22. Architecture of the Monitoring Console 1 Can be abstracted to two frameworks running in parallel - metrics logging framework and metrics handler framework 2 Both frameworks are web services deployed on an application server
  23. 23. Architecture of the Monitoring Console 1 Can be abstracted to two frameworks running in parallel - metrics logging framework and metrics handler framework 2 Both frameworks are web services deployed on an application server 3 SOA Query Metrics Service (sqms) - Logging logging handler framework
  24. 24. Architecture of the Monitoring Console 1 Can be abstracted to two frameworks running in parallel - metrics logging framework and metrics handler framework 2 Both frameworks are web services deployed on an application server 3 SOA Query Metrics Service (sqms) - Logging logging handler framework 4 SPFServlet is the main servlet which handles the requests to the Turmeric runtime. 5 Initializes the metrics logger for logging metrics published by Turmeric services.

  26. 26. SOA Query Metrics Service (SQMS) Figure 3: Architecture of SQMS
  27. 27. Look at the future - Services Portal SOA framework at a good maturity level; it is now necessary to have a single portal for monitoring several aspects of the framework. 1 Ad-hoc querying: Using the data aggregator script 2 Detailed View: Pre-built reports from ad-hoc queries on the metrics, such as Dependent services across multiple levels Dependent SQL queries The respective pools on which the consumer/service reside Performance trends of the individual services/URLs hosted on the given pool in terms of their throughput/hits and response-time over a period of time System metrics trends (e.g., CPU, memory, garbage collection, errors, and etc.)
  28. 28. Other contributions at eBay 1 SifRouting Web : Determine the physical locations of a logical URL, displaying details about it like the pool the service is deployed in, its namespace and so on. 2 Identifying list of services depending on JAXB : Parsing the XML file containing the list of projects across all pools, and examining each project individually 3 Determining Service URLs for services from invoker configuration bean: To enable an unconventional load-balancing feature
