Generating WAAS Before and After Reports
This chapter describes how to generate WAAS before-and-after reports by collecting response time information from the client data source and combining it with information from the Passthru data source.
Collect Client Information for Post-WAAS Impact
This section describes how to collect client information for the after report.
Step 1 Log in to the WAE.
Step 2 Configure the WAE to optimize the server traffic with the following commands:
tfo optimize full
The purpose of this is to have the NAM VB receive optimized flows to enable post-WAAS impact analysis.
Step 3 Wait for 15-30 minutes (or longer depending on the application) for the Client report to collect data.
Step 4 On the NAM GUI, click Monitor > Response Time for the Client data source and collect the baseline server response time numbers. You can get more metrics by choosing the server and clicking Details.

Review Before-and-After Reports For Impact Analysis
Step 1 Log in to the NAM VB GUI.
Step 2 Click Reports > Basic Reports.
Step 3 Choose both the Passthru report and the Client report for Avg Transaction time, and click View.
This will bring up the composite report indicating the average transaction time reduction which is an indication of the end-user experience improvement as shown in Figure 6-2.

Step 4 Click Reports > Basic Reports,
Step 5 Choose both the Passthru report and the Client report for Avg App Delay, then click View.
This will bring up the composite report that indicates the average application delay reduction which is an indication of the server load improvement as shown in Figure 6-3.

Step 6 Click Reports > Basic Reports, and select both the Passthru report and the Client report for Host bits/sec, and select View.
This will bring up the composite report indicating the throughput improvement per host.

Step 7 Click on Monitor -> Response Tim, choose the server and click Multi Segment. This report will show the DRE effects by looking at the Server Bytes.
