PI Interface for Performance Monitor

Learn about latency points

Latency points track the time in milliseconds required to request and receive raw performance counter data. The recommended data type for a latency tag is Float32. Each scan class can contain only one latency point for a particular computer; however, you can define multiple latency points for the same computer in different scan classes. If there are no data points defined for a computer, do not define any latency points for the computer because the overhead required to retrieve the latency data for a computer that you are not monitoring imposes unnecessary workload on the target computer and the network.

To configure a latency point, set its attributes as follows:
