I believe it does not yet record the individual invocations, just the final outcome of the whole processor - so it does not reveal which service was used - as the Provenance layer is quite high up in the stack. It should be possible (as in: editing the XML) to move it further down, if it's right above 'Invoke' it will be capturing provenance for each service invocation. It would not be able to record 'why' there's a second invocation - to do that one would have to trace provenance up and down between each layer to see where it bounced. Do you want me to put down a feature request to capture provenance information on alternative services, like what service was used, and what errors was returned in the failed calls? -- Stian Soiland-Reyes, myGrid team School of Computer Science The University of Manchester ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
