Edit Thresholds for the Optimized Server Segment

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

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

Server Response Time

Measures the time a server takes to start responding to a request made by a client. This value is affected by server speed, application design, and volume of requests.

Server Connection Time

Measures the time a server takes to acknowledge the initial client connection request.

Refused Session Percentage

Measures the percentage of connection requests that were explicitly rejected by the server during the three-way handshake. Part of the Unfulfilled TCP/IP Session Requests report.

Unresponsive Session Percentage

Measures the percentage of sessions where a connection request was sent and the client or server did not respond. Part of Unfulfilled TCP/IP Session Requests report.

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 Server Segment in the third Show Me menu.

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

   Server 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 threshold values for additional metrics.
9. Click OK.
