Usage Guidelines

This command displays DNS analytics statistics for a given VR. This command displays the total DNS queries received from clients, displaying IPv4 and IPv6 queries separately. For a specific client IP address, this command displays domain names queried by the client, number of DNS queries received for the domains, and the time stamp of the last received DNS query. Also, for a particular domain, it displays a detailed view of the specific domain with all the DNS query time stamps separately for IPv4 and IPv6.

Example

The following example shows DNS cache analytics statistics for all clients on the current VR:
