# SCPI: FETCh:DATA:MEASurement<Instance>:IPERf:ALL
value: FetchStruct = driver.data.measurement.iperf.all.fetch()

Queries all client and server results of the iperf measurement. For each server/client instance five results are returned, from instance 1 to instance 8: <Reliability>, {<ServerCounter>, <ClientCounter>, <ServerBW>, <PackErrRate>, <ClientBW>}instance 1, {…}instance 2, …, {…}instance 8 Iperf results are often queried within a loop, to monitor the results over some time. Iperf delivers new results once per second. If your loop is faster, several consecutive queries deliver the same results. Use the <ServerCounter> and <ClientCounter> to identify redundant results and discard them.
