Comment (by karsten): Regarding Objective 3.1 of the MOSS proposal, I'm afraid that the CDF- Relay-* graphs will be out of scope. We had to reduce the budget and were only able to include graphs based on OnionPerf measurements, not based on other Tor descriptors. We can (and should) plan to include CDF-Relay-* graphs in that tool in the future, but the coding will likely have to wait until we have funding for that part. To give you an idea why the CDF-Relay-* graphs are harder to add than the OnionPerf-based onces: we're parsing 1.9M of compressed OnionPerf data for the CDF-TTFB and CDF-DL graphs, but 841M compressed tor descriptors for the CDF-Relay-* graphs. Making the last PDF I attached above kept my local workstation (1T NVMe, 64G RAM) busy for over an hour. Regarding adding graphs to the metrics website, I don't think that we can add any CDFs there without making major changes to the underlying graphing engine. Again, to given an example, the uncompressed data that is graphed in the last PDF I attached has a size of 4.5G. This is way different from existing graphs on the metrics website. I think we're looking at a tool that developers will run locally with data downloaded from CollecTor, a local database, and enough CPU time and RAM available to chew on all the data. This all shouldn't stop us from exploring possible graphs that we might need in the future. And I can make graphs like the last PDF for occasions like the torflow/sbws transition. They will just not be part of the tool that we'll have available once the MOSS proposal is done. I'll move the torflow/sbws discussion over to #33077. If you have any requests for changing the graphs above, except for the votes graph, please comment on this ticket. And when you think we're done, please indicate that here, too.
