GOAL:
What Virtual System Table contains latch information?
GOAL:
Is there a VST that will provide latch timing information that we can get to within promon using the hidden menu?
GOAL:
Is there a VST that can be used to capture statistics from the latch counts screen in promon -> R&D -> debghb -> 6 (hidden menu) -> 11. Latch Counts?
GOAL:
Is there a VST that can be used to collect latch statistics?
FACT(s) (Environment):
All Supported Operating Systems
Progress 9.x
OpenEdge 10.x

Latch statistic information can be accessed via the _Latch Virtual System Table. The _Latch Virtual System Table contains the following fields:
Field Name Data Type Description
_Latch-Busy INTEGER Latch busy count
_Latch-Hold INTEGER User number of the last latch holder
_Latch-Lock INTEGER Latch lock count
_Latch-LockedT INTEGER Used for calculation of duration of lock
_Latch-LockT INTEGER Number, in microseconds, the latch was locked
_Latch-Name CHARACTER Latch name
_Latch-Qhold INTEGER User number of the last queue holder
_Latch-Spin INTEGER Latch spin count
_Latch-Type CHARACTER Latch type
_Latch-Wait INTEGER Latch wait (nap) count
_Latch-WaitT INTEGER Number, in microseconds, of wait or spin time
