The "level" statistics meant to represent the average number of
established connections during the specified time interval (not
connections established per second, that would be "rate"). In other
words, if a "level" shows X established connections, it means that there
were, on average, X established connections at any given time during the
specified time interval.
Binary logs produced with Polygraph 2.2.9 should contain correct
information. However, lx and ltrace had a bug that led to insane levels
being reported. A not-very-much-tested patch is attached. Those who
complained about the bug, please let us know if the patch helps.
Thanks,
Alex.
