This is the total number of probe operations that have
been attempted.
This value is incremented for each start of an RTT
operation. Thus when rttMonCtrlAdminRttType is set to
'pathEcho' this value will be incremented by one and
not for very every hop along the path.
This object has the special behavior as defined by the
ROLLOVER NOTE in the DESCRIPTION of the ciscoRttMonMIB
object.
This value is not effected by the rollover of a statistics
hourly group.
