- XXXX writeme. + These fields are used by the Circuit Build Timeout code, which + tries to learn what times are reasonable for circuit construction, + so that it can reject circuits that take too long to build. + + CircuitBuildTimeBin is a count of circuits that were build + successfully in some timeframe. This entry can repeat; each of + these represents some bar on a histogram. The first integer is a + number of milliseconds; it tells the position of the center of the + histogram bin on the time axis. The second number is a count of + circuits in that bin. + + CircuitBuildTimeAbandonedCount is a count of circuits that we + simply gave up on building because they were taking far too long. + + TotalBuildTimes is the number of circuit build times that we + observed in order to build the above measurements fields. If it + reaches a cap, then older measurements get thrown away.
