question regarding the operation or calculation EWT

[efrainclg95]

Hello expert friends;

I have a question regarding the operation or calculation EWT (StatExpectedWaitingTime) results the following:

1.- I have three groups of virtual agents, in each group I have associated a virtual queue for the calculation of statistics.

2.- I have a routing strategy (Composer) where I process the EWT calculation in the following way:

VALOR_EWT_GRUPO_1 its expression is: _genesys.statistic.sData (colarvirtualgrupo1 @ urs_statserver.Q, StatExpectedWaitingTime)

VALOR_EWT_GRUPO_2 its expression is: _genesys.statistic.sData (colarvirtualgrupo2 @ urs_statserver.Q, StatExpectedWaitingTime)

VALOR_EWT_GRUPO_3 its expression is: _genesys.statistic.sData (colarvirtualgrupo3 @ urs_statserver.Q, StatExpectedWaitingTime)

3.- When making several calls, the value that returns me is the following:

VALOR_EWT_GRUPO_1 = -2147483648
VALUE_EWT_GRUPO_2 = 0
VALOR_EWT_GRUPO_3 = -2147483648

It is a strategy that is in production and for some reason returns those values, it is worth mentioning that in each group of agents there is availability (agents in Ready).

Could you please help me in how to interpret those results, or any suggestions.

Thank you.
