[tor/master] Shutdown libevent _after_ the subsystems.

We calculate latencies as <code>DATARESPONSE - DATAREQUEST</code> for measurements with non-zero values for both timestamps. -We then compute 25th, 50th, and 75th percentiles in the same way as for download times above. +We then compute 25th, 50th, and 75th percentiles in the same way as for download times above. +We also compute the lowest latency within 1.5 IQR of the lower quartile and the highest latency within 1.5 IQR of the upper quartile. Ideally, all measurements would succeed. But it's also possible that some measurements did not complete within a pre-defined timeout or failed for some other reason. diff --git a/src/main/resources/web/jsps/stats.jsp b/src/main/resources/web/jsps/stats.jsp index 6c1955a..443c292 100644 --- a/src/main/resources/web/jsps/stats.jsp +++ b/src/main/resources/web/jsps/stats.jsp @@ -563,9 +563,11 @@ Performance <a href="#performance" name="performance" class="anchor">#</a></h2> <li>date: UTC date (YYYY-MM-DD) when download performance was measured.</li> <li>source: Name of the OnionPerf or Torperf service performing measurements.</li> <li>server: Either "public" if the request was made to a server on the public internet, or "onion" if the request was made to a version 2 onion server.</li> +<li>low: Lowest latency within 1.5 IQR of lower quartile (lower whisker in a boxplot) of time in milliseconds between sending the HTTP request and receiving the HTTP response header.</li> <li>q1: First quartile of time in milliseconds between sending the HTTP request and receiving the HTTP response header.</li> <li>md: Median of time in milliseconds between sending the HTTP request and receiving the HTTP response header.</li> <li>q3: Third quartile of time in milliseconds between sending the HTTP request and receiving the HTTP response header.</li> +<li>high: Highest latency within 1.5 IQR of upper quartile (upper whisker in a boxplot) of time in milliseconds between sending the HTTP request and receiving the HTTP response header.</li> </ul> </div> diff --git a/src/main/sql/onionperf/init-onionperf.sql b/src/main/sql/onionperf/init-onionperf.sql index 7c0176e..536cd45 100644 --- a/src/main/sql/onionperf/init-onionperf.sql +++ b/src/main/sql/onionperf/init-onionperf.sql @@ -130,37 +130,37 @@ GROUP BY date, 2, position) sub ORDER BY date, source, position; CREATE OR REPLACE VIEW latencies_stats AS +WITH filtered_measurements AS ( + SELECT DATE(start) AS date, + source, + CASE WHEN endpointremote LIKE '%.onion:%' THEN 'onion' + ELSE 'public' END AS server, + dataresponse - datarequest AS latency + FROM measurements + WHERE DATE(start) < current_date - 1 + AND datarequest > 0 + AND dataresponse > 0 + AND endpointremote NOT SIMILAR TO '_{56}.onion%' +), quartiles AS ( + SELECT date, + source, + server, + PERCENTILE_CONT(ARRAY[0.25,0.5,0.75]) + WITHIN GROUP(ORDER BY latency) AS q + FROM filtered_measurements + GROUP BY date, source, server +) SELECT date, source, server, - TRUNC(q[1]) AS q1, - TRUNC(q[2]) AS md, - TRUNC(q[3]) AS q3 -FROM ( -SELECT DATE(start) AS date, - source, - CASE WHEN endpointremote LIKE '%.onion:%' THEN 'onion' - ELSE 'public' END AS server, - PERCENTILE_CONT(ARRAY[0.25,0.5,0.75]) - WITHIN GROUP(ORDER BY dataresponse - datarequest) AS q -FROM measurements -WHERE DATE(start) < current_date - 1 -AND datarequest > 0 -AND dataresponse > 0 -AND endpointremote NOT SIMILAR TO '_{56}.onion%' -GROUP BY date, source, server -UNION -SELECT DATE(start) AS date, - '' AS source, - CASE WHEN endpointremote LIKE '%.onion:%' THEN 'onion' - ELSE 'public' END AS server, - PERCENTILE_CONT(ARRAY[0.25,0.5,0.75]) - WITHIN GROUP(ORDER BY dataresponse - datarequest) AS q -FROM measurements -WHERE DATE(start) < current_date - 1 -AND datarequest > 0 -AND dataresponse > 0 -AND endpointremote NOT SIMILAR TO '_{56}.onion%' -GROUP BY date, 2, server) sub + MIN(CASE WHEN latency >= q[1] - ((q[3] - q[1]) * 1.5) + THEN latency ELSE NULL END) AS low, + TRUNC(AVG(q[1])) AS q1, + TRUNC(AVG(q[2])) AS md, + TRUNC(AVG(q[3])) AS q3, + MAX(CASE WHEN latency <= q[3] + ((q[3] - q[1]) * 1.5) + THEN latency ELSE NULL END) AS high +FROM filtered_measurements NATURAL JOIN quartiles +GROUP BY 1, 2, 3 ORDER BY date, source, server;
