Domain Trend
The Domain Trend tab is available from Cisco vManage Release 20.6.1. It was called App Trend in In Cisco vManage Release 20.6.1 through Cisco vManage 20.8.x. This tab appears only when DNS discovery is enabled and displays trends for metrics and events in an application flow. Hover your cursor over the data points in the tab to see detailed information.
The client network delay (CND) and server network delay (SND) information that appears on this tab are measured by the applications' TCP traffic. DNS request frequency shows how often a SaaS application is visited. HTTP probe response time and loss rate are measured by probes that are sent by a router to the SaaS application server to detect a reachable direct internet access (DIA) network path and help evaluate the benefit of deploying a DIA traffic policy.
From the Chart Metrics drop-down list, you can choose the metric types for which you want to view information. From the Devices drop-down list, you can choose specific devices for which you want to view data. By default, trend information appears for all metric types and all devices.
You can limit the display to trends that occurred within a specified time, or those that occurred within a specified period. You can choose a period of 1, 10, or 30 minutes, or 1, 2, or 5 hours. You also can click Custom and enter a date and time range, or click Real Time to display information as it is collected.
