Description
Currently, there is no efficient and deterministic way to know in which context (siteId) an event was generated. The current work-around for this is to parse the Ref field and try to guess the context.
Events can be sakai scoped (with new contextId field set to null) or site scoped (contextId set to siteId). This would probably involve adding a column to SAKAI_EVENT and a setter a getter for it in the Event class.

IU needs this implemented by August 16th, 2007 for a production roll out of Site Stats. Andrew will work with Glenn to make it happen. Thanks, L

removing the 2.5.x merge status as branch managers discussion determined this a fairly substantial change in functionality and thus, didn't meet the criteria for 2.5.x

There are 3 ways in which the CONTEXT can be set:
1. The entity code for the event reference has a parser which will return the context for the reference concerned, e.g. in references like /content/group/53450fdc-643a-4bf9-a860-adca9c72bbaf/, the context is embedded in the reference.
2. If the reference itself doesn't yield a context from the reference's service, then the tool context in which the request thread is executing is used as the context. This means that events posted by a tool placed in a site in response to a user action will get the context of that site.
3. A tool or service may explicitly pass the context when it posts events using an extra parameter.
In some of your examples:
Creating a new site - you do so from your My Workspace, so the context is your workspace's site id, except for some events where the context is derived from the ref.
alias.add events may come from new site creation, or may come from the site itself (e.g. adding Email Archive in Site Info vs configuring it in My Workspace when creating a site).
As you've noted, the CONTEXT is not completely consistent but it is a progressive improvement on 2-5-x as it allows many more events to be reliably associated with sites (viz. for those tools which use event REFs that don't include a site id).
Feel free to add JIRAs for cases that you think are truly inconsistent. It's possible some of those inconsistencies could be straightened out by getting the tools/services to explicitly set the context to whatever is most appropriate.
Cheers

Please forgive a very non-technical question...
I am just beginning to get familiar with the way Sakai 2.6 logs
events, particularly with regard to a new column in the table "context"
It appears that the goal of this field is to grab the site_id that is
associated with this event, which is very helpful.
However, it appears that sometimes this field is not grabbing the
site_id at all, resulting in a (null). Othertimes, it seems to grab
the user's ID or the ID of their My Workspace instead of the site they
are using.
If someone can please explain what's going on, where the known gaps
are, etc. I would greatly appreciate it, particularly since this
information does not appear to be captured in the relevant JIRA
entries (SAK-10801, SAK-13809)
Thanks! Steve
