Overview

The Context Aggregator in POMBA consumes a service audit request from DMaaP and initiates the gathering of context-specific service information via a set of "builders". The information available about the service within each context (i.e. from each builder) is collated and a single report is then published to DMaaP where it can be consumed.

Currently, if a context builder is incapable of providing data, no data is published to DMaaP. Future work will allow for the publishing of data when one or more builders do not provide data (either due to the service not existing in that context or due to error).
