2. 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 using the open-source
plugin
Define type libraries, error libraries for re-use across
applications
Turmeric Monitoring Console: The open-source equivalent of
SMC (eBay’s internal monitoring console)
3. Turmeric SOA Framework
1 Client Runtime - Client application code written by the
consumers of the service. Service Invocation
Framework(SIF)
4. Turmeric 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.
7. Where does services monitoring fit in?
1 Develop a service or a consumer to a service using the Eclipse
SOA plugin
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

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

Integrate the open source monitoring console
into the internal SOA framework!
16. Comparison with the Internal Monitoring Console (SMC)
Issues in SMC
1 Outdated V4 technology for constructing the GUI
17. Comparison with the Internal Monitoring Console (SMC)
Issues in SMC
1 Outdated V4 technology for constructing the GUI
2 Very slow!
18. Comparison with the Internal Monitoring Console (SMC)
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1 Outdated V4 technology for constructing the GUI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

8 OPEN SOURCE!
28. Metrics Collected in TMC
1 Top Volume - Call count; the number of times the service is
called
2 Top Errors - Errors which have been raised while invoking the
service
3 Top Performance - Average response time of the service
4 Consumer Traffic - Consumers who have accessed this service
29. Architecture of the Monitoring Console
1 Can be abstracted to two frameworks running in parallel -
metrics logging framework and metrics handler framework

37. Demo

2 Sample REST URLs for metrics
3 Simple Consumer for TMC
4 A simple service call to a Turmeric Service through a Java GUI
5 Walkthrough of database schema and significant
implementation classes
38. 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.)
