Intervals and data sharing
When using the CAE Browser Client in a data sharing environment, the intervals that are shown for selection are obtained from the master Query Monitor Subsystem of the subsystem group.
When you are retrieving data from the other Query Monitor Subsystems, the CAE Server chooses intervals from the other Query Monitor Subsystems that overlap with master intervals by more than 30 seconds.
All Query Monitor Subsystems in a group have the same interval length, and if you specify INTERVAL_MIDNIGHT(Y) in CQMPARMS, the intervals will generally have the same start and end times as the master intervals.
