Trouble with onionperf visualize and S61 performance experiments
by George Kadianakis 07 Dec '20

Hello Karsten, hope you are doing well! I've been working on the S61 performance experiments [0] and I would appreciate some help with onionperf. I have done various onionperf measurements using something the following command: $ onionperf measure -i --tgen ~/tgen/build/src/tgen --tor ~/onionperf/tor/src/app/tor --drop-guards 10 I put each of the measurements on a different directory and now I want to analyze them and derive the CDF-TTFB graphs etc. I attempted doing that using the following calls: $ onionperf analyze --tgen ./tgen-client/onionperf.tgen.log --torctl ./tor-client/onionperf.torctl.log $ onionperf visualize --data onionperf.analysis.json.xz "test" Unfortunately, the 'visualize' call can fail for the attached 'onionperf-mbps.json.xz': $ onionperf visualize --data onionperf.analysis.json.xz "Test Measurements" 2020-11-03 15:51:31 1604411491.540736 [onionperf] [INFO] loading analysis results from /user/tmp/onionperf/analysis/onionperf.analysis.json.xz 2020-11-03 15:51:31 1604411491.577864 [onionperf] [INFO] done! 2020-11-03 15:51:31 1604411491.586845 [onionperf] [INFO] NumExpr defaulting to 8 threads. /user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/onionperf/visualization.py:251: UserWarning: Attempting to set identical left == right == -1e-06 results in singular transformations; automatically expanding. /user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/onionperf/visualization.py:251: UserWarning: Attempting to set identical left == right == -1e-06 results in singular transformations; automatically expanding.

Any idea what I might be doing wrong? Is there any other data you might need to help me with this? Thanks a lot!
