Response Time Monitoring from WAAS Data Sources

The NAM processes the TCP flow data exported from the WAAS and performs application response time (ART) calculations and reports. You use the NAM GUI to create a WAAS data source to monitor WAAS traffic statistics. In addition to ART, NAM monitors and reports other traffic statistics of the WAAS data sources including application, host, and conversation information.

The NAM provides different ART metrics by collecting data at different points as packets flow along their paths. The NAM provides five different collection points, each represented by a WAAS data source. Figure 2-3, “WAAS Data Sources (Data Collection Points)”, shows an example of the data collection points. The solid line represents data exported from a WAAS device and/or directly monitored traffic like SPAN. The broken line represents data exported from a WAAS device only.

You can use the NAM GUI to configure data sources at the locations in the network described in Table 2-11, WAAS Data Collection Points.

		Table 2-11	WAAS Data Collection Points
		Setting		Description
		Client		This setting configures the WAE device to export the original (LAN side) TCP
				flows originated from its clients to NAM for monitoring. To monitor this point,
				configure a Client data source.
		Client WAN		This setting configures the WAE device to export the optimized (WAN side)
				TCP flows originated from its clients to NAM for monitoring. To monitor this
				point, configure a Client WAN data source.
		Server WAN		This setting configures the WAE device to export the optimized (WAN side)
				TCP flows from its servers to NAM for monitoring. To monitor this point,
				configure a Server WAN data source.
