DNS Performance RTT Details report
DNS Performance RTT Details report overview
The DNS Performance RTT Details report shows the network quality in terms of DNS responsiveness for the selected DNS servers.
Note: The DNS servers are modeled as applications and must be selected from the Application drop-down menu in the prompt section of the report.
Note: This report requires special study statistics collection by an NSP Flow Collector for each modeled DNS server application. See the workflow to configure AA Cflowd special-study statistics collection in the NSP NFM-P Statistics Management Guide for configuration information.
If the user chooses an application that does not represent a DNS application, the application will appear in the report but the information provided will be invalid. If the user chooses a DNS application that is not configured for special studies collection, the application will not appear in the report.
