WSO2 introduced a new version of its Business Activity Monitor (BAM) product. BAM 2.0 features a modular architecture that allows each component to scale independently. It uses a new event receiver and data agents to efficiently capture and transmit data. The analyzer framework is the core of BAM, allowing users to build custom sequences of analyzer units to aggregate, analyze, and operate on data. The presentation layer provides dashboards, reports and alerts for visualizing the results without heavy processing. BAM 2.0 aims to improve performance, scalability, and customizability compared to previous versions.

3. Business Activity Monitoring
“The aggregation, analysis, and
presentation of real-time information
about activities inside organizations
and involving customers and
partners.” - Gartner

4. Convergence of SOA & BAM
“Some people would go SOA
just for BAM”
“With business functions as
services, monitoring a whole
company is just monitoring
the services”

5. Modelling a monitoring scenario
●
The flow of a monitoring scenario will consist of 3
parts
– Data Aggregation
– Data Analysis
– Data Presentation

6. Aggregation
●
Capturing data
●
Event storage
●
What data to capture
as events?

7. Analysis
●
Data operations
●
Operate on old data or
new data or both?
●
Building KPIs
● Building BI

8. Presentation
●
Visualizing KPIs
●
Custom Dashboards
●
Tools
● Not just dashboards!

9. BAM 2.0 – A complete revamp
Performance, Scalability and Customizability

10. Why a complete revamp?
●
Performance – Extremely important to be non-
intrusive
●
Scalability – Scalability on multiple sides
● Customizability – Everyone's use case is different,
even in the same organization ex: operations,
CEOs, marketing

11. Use Cases of BAM
●
Tracking server statistics
●
Auditing
●
KPI Monitoring
● Fault detection
● Business Intelligence

12. Architecture

13. Modular Architecture
●
Each component is individually scalable
●
Makes use of the Carbon platform's
install/uninstall feature. Ex: Download BAM,
uninstall all features except for the Event
Receiver, and you end up with a BAM server with
just the Event Receiver
●
Based on event load and data volume, we can
decide what needs to be scaled

14. Event Receiver

15. Data Agents
●
Get data across to BAM – handlers, mediators,
web services
●
Simple API to embed for 3rd party applications
● Asynchronous & non-blocking
● Minimum processing
● Thrift for high performance message throughput

16. Agent API
EventReceiver eventReceiver = new EventReceiver();
eventReceiver.setSocketTransportEnabled(true);
eventReceiver.setUrl("https://localhost:9443/");
eventReceiver.setUserName("admin");
eventReceiver.setPassword("admin");
eventReceiver.setPort(7611);
events.add(johnEvent);
BasicConfigurator.configure();
setTrustStoreParams();
Agent agent = new Agent();
agent.publish(events, eventReceiver);
agent.shutdown();

17. Event Receiver
●
Extremely efficient with minimum conversions
●
In-built security
● Invisible in most use cases

18. The Analyzer Framework

19. The Analyzer Framework (cont.)
●
The workhorse of BAM
●
A unit is an analyzer; Ex: get, aggregate, order,
failure, alert
●
A set of analyzers consist of an analyzer sequence
● Schedule the sequence; Ex: once a day, once a
minute, every Wednesday at 12.15, every 30th at
12 midnight
● If the given analyzers don't work, just plug your
own – custom analyzer

20. A sample sequence – UI

21. A sample sequence - xml
<analyzerSequence name="productSummarizer">
<trigger cron="1 * * * * ? *"/>
<analyzers>
<get name="orders" fromLastCursor="true" batchSize="3"/>
<lookup default="EVENT"/>
<aggregate>
<measure name="quantity" aggregationType="SUM"/>
</aggregate>
<put name="productSummary" indexRow="allKeys">
</analyzers>
</analyzerSequence>

22. A sample 'index' analyzer - UI

23. The Presentation Layer

24. Presentation Layer
●
Not just dashboards, also includes alerts, reports
●
Gadget IDE - Quick and easy WYSIWYG tool
●
Minimum processing – Let the analyzers do that
● Point to a data source and build your visual
elements
