As reported by customers:

"total lock time" -> "locks(micros) w: 1629310"

"global lock wait time", -> a quantity that constitutes part of "locks(micros) w:" but is not explicitly broken out in 2.6 logging and therefore is unknowable. It can be bounded as at least 1629310us / 1000 - 815ms = 814ms and at most 1629ms. (And it's a coincidence that the ratio is almost exactly 2:1.)

"total time" -> "815ms" at end of line, to which we'd have to add the (unknowable) "global lock wait time" to get an (unknowable) total, total time.
