Edit Thresholds for the Optimized Client Segment

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

The management console calculates the following metrics from the Client 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.

Retransmission Delay

Measures the 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.

Transaction Time

Measures the elapsed time from when a client sends the request (packet-level or transaction-level) to when the client receives the last packet in the response.

The management console shows this type of response time data in the Response Time Composition: Average report on the Engineering page. The management console does not open incidents when the Transaction Time threshold is crossed.

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 Client Segment in the third Show Me menu.

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

   Client Segment Thresholds opens.

6. Customize the performance thresholds, Minor (yellow) and Major (orange), for each response time metric:
   • 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.

   For information about setting threshold properties, click Help.

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