Dear ServiceMix Users,
Together with my friend I'm working on a subject of monitoring a JBI compliant ESB. It is actually a subject of out Master Thesis :>. So we were focusing on ServiceMix and OpenESB implementations. At the beginning we were total noobs ;) (maybe we still are) but we cracked through the JBI specification and analyzed how things look in ServiceMix and OpenESB. After some time of research we have decided to create a solution that would be 100% (or close to that :>) JBI compliant and would not assume anything about specific mechanisms (either SMix or OpenESB) [Unfortunately that was not truly possible :|. For example SMix has this not JBI compliant 'processInbound' method which is often used in DeliveryChannelImpl]. We decided to go AOP way. We created an sniffy aspect which intercepts everything that goes through JBI's DeliveryChannel implementations. It turned out that it was quite easy. We went a step further and provided a mechanism of correlation MessageExchanges that are related - in fact it is very similiar to ServiceMix's correlationId (we examined ThreadLocal's oriented implementaion of it). So at the end of the day we have a mechanism that without a slight code modification of JBI Container itself is able to intercept all MessageExchanges flying through the components. At the beginning of our work the assumption was that our solution should be inline with the idea of Application Response Measurement (http://www.opengroup.org/arm). We studied the ARM specification and decided that it is far to complicated for our purposes but we can use the concepts invented there !! An Idea of profiling tool for JBI came up !! We were wondering how the JBI profiling session could look like and what would be most useful ?? We thought that it would be interesting if at the end our GUI would be able to draw something like Sequence Diagram (http://upload.wikimedia.org/wikipedia/en/3/32/CheckEmail.png). The entities that would be on such diagrams could be specific endpoints in componets(BC and SE). Each arrow would be connected with some ME exchange and would be described by the time that elapsed and maybe some other information (we are still working on it). So why I am telling You all this things. We decided that in scope of our MasterT we want to make same useful tool that could be really handy for both Developers and Users of JBI Containers. My question is: Could such JBI Profiling Tool be useful ? I am aware of ServiceMix's visualizations: dotViewEndpointListener and dotViewFlowListener (they are based on MessageExchangeListeners). Those were not an options for us because we wanted JBI compliance. But I am aware that functionalities of our mechanism would overlap with those dotViewThingies So what do You think about it ? Thanks in advace, Kind Regards, Marek Psiuk
