[DISCUSS] CallContext and related questions
Hello developers. I am implementing CADF event logging . In "server"
project, in class ActionEventUtils, I am calling my method to log the CADF
event.
Something like
createCadfRecord(EventVO event)
All the mapping and information I am using for CADF are being extracted
from the event.
My problem is what happens when I want to use information from other
classes (ApiServlet.java)? I am not asking for general information on
interclass communication.
eg. I want to use the clientIpAddress from ApiServlet.java to
ActionEventUtils.java
Is CallContext a valid choice/solution?
In ApiServlet.java, method processRequestInContext, I am adding to
CallContext.current() the ip address (or any arbitary data).
In ActionEventUtils when I try to get that data the value is null. After a
little debugging I noticed that the contextid in ActionEventUtils is
different from that in ApiServlet.
Any ideas?
Thank you
Nikos Dalezios

Yes, that would seem appropriate

To simplify the question,
How to share a variable/object from ApiServlet class to ActionEventUtils
class? Is CallCotnext the correct way?

Thank you Daan,
I'm proposing an alternative format to store events (at the moment to a log
file, not to database).
You are right about the fact that all necessary information is in the
event.
But, in order to extend the auditing capabilities, additional information
would be nice to be added to the event
such as ip address and agent of the request.
If I've got it right, in Cloudstack the event is being created and posted
to db in ActionEventUtils.java (server project).
Additional information is being stored to log files (api.log) in
ApiServlet.java (server project).
My goal is to combine the information of the EventVO (as defined in
CloudStack) and the api.log record

Nikos, I am not sure if I understand your objective. It would seem to me
that all information to proces an event should be in the event. Does it
suffice to add information to the event message for your purposes?
