Chapter 3      Using IPM to Measure Network Performance
    Measuring Network Performance for SNA
You can customize both the request and response payload sizes to model traffic flow for various 
applications. The SNA operations also measure availability and errors for SNA services.
To measure end-to-end performance for SNA:
Step 1
Define a device as the source device from which to measure performance. For details on defining a 
source device, see the 
.
Step 2
Define a device as the target of SNA echo requests from the source device. For details on defining a 
target, see the 
.
To control how statistics are collected, use one of the default SNA operations, or define your own SNA 
Echo operation. For details on defining an SNA Echo operation, see the 
Step 3
Define a collector to measure performance between the source router and target you defined. For details 
on defining a collector, see the 
. If you set the collector’s schedule to On Demand
