The scanning process will involve calling running two Simple
Workflow workers:
...
- An interface to a temporary high-resolution data window, backed by any of several various implementations
- Long-term RRD (implemented with rrd4j and backed by any of a variety of storage mechanisms).
Diagrams
Below is a diagram of the basic data flow for the application. I've endeavored to show the relationship's of all the moving parts, and specifically called out what needs to be built as part of this project.

- the main purpose of this data window would be essentially providing a source of data for an update stream, and possibly a place to buffer pushing the data into long-term storage
- Long-term storage
RRD Considerations
See the page on RRD Size Estimates for information about what the storage needs are. (Hint: they're small).
