This section details the dashboards of DNS Dashboards category. For more information on operations that can be performed on reporting dashboards, see About Dashboards.

The dashboards covered in this section are as follows:

DDNS Update Rate Trend

The DDNS Update Rate Trend dashboard provides information about the dynamic DNS (DDNS) updates that occur on the DNS service. The default dashboard shows a line graph that tracks the rate of DDNS updates (counts per second) by query type in the given time frame.
This dashboard displays DDNS updates per second by the following query type: Success, Failure, Reject, and Prerequisite Reject. The time is displayed according to the time zone specified on the reporting server in UTC format. You can mouse over the graph to display the coordinates of any point in the graph.

DNS Cache Hit Rate Trend

The DNS Cache Hit Rate Trend dashboard provides information about the cache hit ratio of selected Grid members. The dashboard shows line graphs that track cache hit rates over a given time frame. Note that if you have one member with two DNS views and requests are sent to only one DNS view, the maximum hit rate is 50% (not 100%) for the member because one DNS view has 100% hit rate and the other has 0, and the average is 50%.

Note that the DNS Cache Hit Ratio Trend is the search associated with the DNS Cache Hit Rate Trend report.

DNS Daily Peak Hour Query Rate by Member

The DNS Daily Peak Hour Query Rate by Member dashboard shows the average or peak DNS Query rate at the busiest hour within a day. This dashboard will help you identify the load that is being carried by each DNS Server during busy hours. This dashboard can help you plan better for capacity and reduce the risk of overloading DNS devices.
This dashboard displays the following information

• Time: Timestamp of events.

• QPS: Query per second. QPS is calculated with two steps: 1) find out the busiest hour (on the top of hours such as from 8:00am to 9:00am) by average hourly QPS, and 2) use that hour's max/avg QPS as they daily max/avg QPS.

DNS Domain Query Trend

The DNS Domain Query Trend dashboard shows the trend of DNS queries for specific domains. This dashboard displays the DNS query trends for queries generated from both the internal and external sources.

Note that the DNS Top Client report is not NAT client aware and therefore this dashboard does not show information for NAT'ed clients.
To generate data for DNS Response Latency Trend dashboard, the Grid member enabled for DNS service queries itself for PTR record 1.0.0.127.in-addr.arpa every minute. NIOS will not exclude such DNS queries and displays default client 127.0.0.1 in the DNS Top Clients report.

DNS Top Clients Per Domain

The DNS Top Clients Per Domain dashboard lists the clients that have the most DNS queries for specified domain names and their subdomains. The dashboard shows a horizontal bar chart that lists the clients that have the most total counts of DNS requests and their percentages over a given time frame. You can display the report data in bar chart form or in table form. The domain or domains are specified using filters. The default dashboard displays the top 10 clients within the last 24 hours.
You can define the domains for capture in the Grid Reporting Properties editor (Administration tab –> Reporting tab –> Grid Reporting Properties –> DNS tab –> Monitor queries made to the following domains checkbox).
