Edit Thresholds for the Optimized WAN Segment

For a WAN-optimized application, edit the performance thresholds for each network segment.

The management console calculates the following metrics from the WAN segment:

Network Round Trip Time

Measures the time a packet takes to travel between the server and clients on a network, excluding loss. Application, server, and client processing time are excluded.

Network Connection Time

Measures the time the client takes to confirm the server’s connection acknowledgment. Delay is likely to be caused by network latency.

Effective Round Trip Time

Includes Network Round Trip Time plus delays caused by retransmissions. Set a threshold for this metric to monitor performance degradation due to retransmissions.

Retransmission Delay

Measures additional delay in the Network Round Trip Time due to retransmissions. The data displayed is an average across all observations, not the actual retransmission time for each transaction.

Follow these steps:

1. Click the Administration page.
2. Click Policies, Performance Thresholds in the Show Me menu.
3. Scroll to the Performance Thresholds List.
4. Click to edit a WAN-optimized application. The Segments column identifies WAN-optimized applications. If the management console has observed optimized application traffic by network segment, the status of the Segment column is Yes.
5. Click WAN Segment in the third Show Me menu.

   If the management console has not calculated response time metrics from the WAN network segment, the WAN Segment command is not displayed.

   WAN Segment Thresholds opens.

6. Customize the metric thresholds for Minor (yellow) and Major (orange) incidents:
   • Choose a method for measuring a threshold value and then specify a threshold value.
   • Specify the minimum number of observations, or times that the management console must calculate a metric during a 5-minute interval, under Minimum Observations. If the management console does not calculate the metric the minimum number of times, the status of the metric is Unrated for the 5-minute interval.

7. Click Apply.
8. Repeat these steps to edit the Minor and Major threshold values for additional metrics.
9. Click OK.
