FOR OMG BPM/SOA COP WORKING SUB-GROUP, 2010-06-02 EXAMPLE: USE OF BPM TO MONITOR AN ESB-CENTRIC INTEGRATION Alexander Samarin Richard Vigniel The situation

• Business issue

• Some « pieces of work » got lost between applications which are involved in a business process

• Degree of synchronisation of some applications is low

• Technical issues

• No overall coordination or monitoring over those applications

• The business process is implicit

• Need for the real-time monitoring for IT

• Need for the real-time monitoring for business

• There is no « bigger » architecture

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration ESB-centric view – only flow of data Enterprise Service Bus (ESB) Application 1 Application 3 Application 2 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Process-centric view – both flow of control and flow of data Process Application 1 Application 3 Application 2 Primary importance – the result of working together, but not individual exchanges (like in the football) 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Context

• The business goal (short-term)

• Implement monitoring WITHOUT disruptive changes in the infrastructure – simple, quick and cheap

• The techniques

• Make the process explicit

• Discuss monitoring approaches

• Use the architectural approach to

• Mix BPM, SOA, ESB, BAM, BEM, CEP

• Select tools which are good citizens (not expensive, easy to deploy, fit to existing culture, real “worker”, not exotic, etc.)

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration In-house understanding of the process

• Imagine a token moving through this process – any need for loops?

• Merging is implicit

• Too technical

• Actually it is the production line

• Good for e-gov?

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration

• Three parts of the tax declaration

• La décision de taxation ICC/IFD,

• Le ou les factures associées (parfois aucune),

• Le relevé de compte.

• Merging is explicit (SP01 and SP02)

• Only business activities are visible

• Takeover time between blocks

• SLA of each block

What to monitor? 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration SLA SLA SLA SLA SLA SLA Takeover time Takeover time Takeover time SLA of each block

• The message event (E02) which should throw an alarm after the timer event (E01) is not activated because of the cancel event (E03)

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Takeover time between blocks

• The exclusive event gateway (G01) is waiting for the end of transition (E04) or timer (E05). The latter initiate an alarm.

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration General recommendations

• Both block SLA and takeover time can be monitored in different ways

• Block SLA can be monitored by a particular tool itself

• Takeover time should be monitored by a “third” party

• Monitoring should take into considerations dependencies between events – if a tool is broken there is no need to alarm about SLA of process instances which use this tool (similar to NAGIOS functionality)

• Transformation and technical routing of messages by the ESB

• Transmission of message into queues JMS

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Test scenario

• A java application generates and sends the following messages into JMS queues

• 30 messages « Start monitoring »

• 28 messages « End of Taxations »

• 24 messages « End of Facturations »

2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Report – initial view No process instances 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Messages « Start monitoring» sent 30 instances are instantiated 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Messages « End of Taxations  » sent 28 instances in the state « tax » Ratio of groupping = 0% 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Messages « End of Facturation » sent 24 instances terminated Ratio of groupping = 85% (24/28) 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Report Designer Data Sets Mise en page Propriétés 2010-06-02 Example: Use of BPM to monitor an ESB-centric integration Conclusion

• Intalio|BAM (BIRT) allowes quick implementation of complex reports

• Deep knowledge of SQL is mandatory

• Drill down feature has not been tested

• Messages have been transformed by the ESB

• Intalio|BPM facilitates the capture of metrics

• BPM does not bring a lot in this example, because the process is simple and passive (or shadow)

• BPM added values comes from complex rules which are explicitely expressed (in comparison with CEP)

• BPM with active processes is naturally integrated with BAM
