[overlord-issues] [JBoss JIRA] Closed: (SOAG-106) Service activity event model

Service activity event model ---------------------------- Key: SOAG-106 URL: https://jira.jboss.org/browse/SOAG-106 Project: Overlord Issue Type: Task Security Level: Public(Everyone can see) Components: Behavioural Monitoring Affects Versions: 1.0 MR3 Reporter: Gary Brown Assignee: Gary Brown Fix For: 1.0 MR3 Definition of event model for reporting service activity from various runtime platforms, and storing the information in a repository. Event model needs to be extensible, although there should be a fixed core of standard events defined. The events could be interaction based, i.e. indicating messages being sent and received, or task based i.e. task started and finished. Data related events could also be stored, when variables are updated. The actual events stored could be dependent upon filters defined in the activity recorders. Question: should the event model be XML based? Or should it support message content being non-xml - i.e. Java objects, or other binary formats? Possible non-XML message contents could be reported in a summarised XML form, to provide enough useful information. The events recorded from a service may be based on local service identity information. This can be used to group events generated by a particular session at a service, but they won't necessarily be business relevant. To be able to correlate service activity, associated with a particular business transaction, across multiple services, it will be necessary to derive business identity that is common across services. However, only some of the reported service activity events may contain the business identity properties - so these should be used to associate the business identity with the local technology specific service/session identity information.
