DNS Performance Session Details report

DNS Performance Session Details report overview

The DNS Performance Session Details report shows the number of DNS sessions for a specified set of applications.

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.

Use cases
