[JBoss JIRA] Created: (SOAG-112) Service Activity Console

Service Activity Console
------------------------
Key: SOAG-112
URL: https://jira.jboss.org/jira/browse/SOAG-112
Project: SOA Governance
Issue Type: Task
Security Level: Public (Everyone can see)
Components: SAM
Affects Versions: 1.0 MR3
Reporter: Gary Brown
Assignee: Heiko Braun
Fix For: 1.0 MR3
Service activity visualisation, initially aimed at presenting information generated by the Overlord Process Governance Service Validators.
Three main views are required:
1) Service instance summary
This should be a tabular view of the service instances, defining high level information such as the service instance id, name, status. It would be good if the rows could be colour coded to reflect the highest error state - e.g. warning = yellow, error = red. Normal could just be grey/black, rather than green.
2) Service instance details
When a service instance is selected from the summary view, the Service Instance Details view should show a list of the events that are associated with the service instance. The details for the rows will include timestamp, event summary, event status.
3) Service activity event details
When a service instance event is selected, enable the event payload to be presented - initially just as XML, although eventually this could be transformed into a suitable presentation representation (if a definition is available).
A fourth view may also be required to just show error messages, although this could be combined with (1).
View (1) should also provide a filtering mechanism, which eventually should enable filtering based on business attributes. But for the initial release, it should be possible to filter based on time range.
The event stream will be based on an event model defined in issue https://jira.jboss.org/jira/browse/SOAG-111
For this initial version, the console will only operate on current events - there won't be any persistence support, or querying of historic events.

Persistence support for scribble service validator
--------------------------------------------------
Key: SOAG-109
URL: https://jira.jboss.org/jira/browse/SOAG-109
Project: SOA Governance
Issue Type: Task
Security Level: Public (Everyone can see)
Components: Behavioural Monitoring
Affects Versions: 1.0 MR3
Reporter: Gary Brown
Assignee: Jeff Yu
Fix For: 1.0 MR3
The behavioural sessions, constructed within the scribble monitor when processing service activity information, can optionally be stored in a database.
This means that as each relevant service activity event is received, the current behavioural session will be retrieved from the database, and used to evaluate the next service activity message.
The other approach would be to evaluate the complete history of events, for a particular service session, when the next service activity event for that session occurs. This approach means that intermediate session information does not need to be stored, and it could also mean that the session could be evaluated against services as the description is updated (although this may depend on what type of versioning is used - i.e. it may actually need to use the old version of the process description).

Trailblazer example documentation improvments

Key: SOAG-77

Affects Versions: 1.0 MR1
Reporter: Jeff Yu
Assignee: Mark Little
Fix For: 1.0 MR2
Thanks Jeff Delong for following suggestions and feedback.
------------------------
A few suggestions on how to improve the documentation:
1) Have the readme refer to the docs/samplesguide/SamplesGuide. While much of the information is redundant, the SamplesGuides has the information on the ChoreographyMonitor and the error-client.
2) In the SamplesGuide.pdf, the code snippet from LoanBroker.java is unreadable.
3) Under 10 2 It says to run the commands from step 6 on. Is that really necessary?
4) Add more information on the role of the LoanBroker.java class, and how it's choice of
if (score >= 4) {
//step 3a - send to Bank - async
System.out.println("sending to first Bank...");
sendToBank(bank1Invoker, customer, "b1");
Implements the Choreography conditional expression: cdl:getVariable('creditCheckResult','','//@score') >= 4
5) It would be nice to have an architectural discussion here about how this choreography is being monitored. (perhaps this is described in another document I have yet to read).

[JBoss JIRA] Created: (SOAG-68) Async Perform

Async Perform
-------------
Key: SOAG-68
URL: https://jira.jboss.org/jira/browse/SOAG-68
Project: SOA Governance
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Reporter: Gary Brown

Currently the Brokerage example iterates through a list of suppliers to find the best quote, before proceeding to perform a credit check and complete the transaction.
However the list of suppliers is processed using a loop containing a synchronous perform, so each supplier is dealt with in turn.
The next step is to cater for an asynchronous perform, where the suppliers can be dealt with concurrently (i.e. so multiple sub-sessions active at the same time). This would require the 'WhenAction' to block, awaiting all of the sub-sessions to complete, before making its decision regarding the best quote.

Persistence storage for service activity information.
Information will be received from a variety of event sources reporting service activity information - which will then be persisted in the database.
Information enrichment needs to be supported. This can be in the form of extracting conversation identity information, or other custom properties, which can then be used to query the service activity information.
NOTE: Although the storage of service activity information could be used to trigger a variety of activities, including deriving the properties described above, as well as performing higher level validation, the behavioural validation is dependent upon the conversation identity fields - and therefore it may be better to derive this base information when recording the service activity information. But other information and validation tasks can be triggered based on the storage of the service information - possibly using DNA at some point (i.e. the sequencing mechanism).
