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

Note

The DNS dashboards display data only for these records: A, AAAA, CAA, CNAME, DNAME, DNSKEY, DS, MX, NAPTR, NSEC, NSEC3PARAM, NSEC3, NS, PTR, RRSIG, SOA, SRV, TLSA, TXT, ANY, AFSDB, HINFO, ISDN, KEY, MB, MD, MF, MG, MINFO, MR, NXT, RP, RT, SIG, WKS, and X25. 

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

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.

DNS Query Rate by Member

The DNS Query Rate by Member dashboard shows the trend of DNS queries for selected members. This dashboard displays line graphs of DNS query trends for the selected members over a given time frame.

DNS Top Clients

The DNS Top Clients dashboard lists clients that have the most DNS queries. The dashboard shows horizontal bar charts that list clients that have the most total counts of DNS requests and their percentages over a given time frame. The default dashboard displays the top 10 clients within the last 24 hours. 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 check box).

DNS Top NXDOMAIN / NOERROR (no data)

The DNS Top NXDOMAIN / NOERROR (no data) dashboard shows the number of responses transmitted by the specified name server(s) indicating a client-specified non-existent domain name. This dashboard displays horizontal bar graphs of DNS query trends for the selected members over a given time frame.

  • NXDOMAIN indicates that no records of any type existed for the query name.
  • NOERROR (no-data) indicates that no data existed for the requested resource record type; other records may exist for the query name.

Note

The statistical data on the IB-4030 appliance may not be absolutely accurate if acceleration cache entries are reused after the TTL expiration for other data during a given report monitoring interval. The default interval is 10 minutes.

The statistical data on the IB-4030 appliance may not be absolutely accurate if acceleration cache entries are reused after the TTL expiration for other data during a given report monitoring interval. The default interval is 10 minutes.

DNS Top SERVFAIL Errors Sent

The DNS Top SERVFAIL Errors Sent dashboard lists the top query names resulting in Infoblox name servers sending DNS response packets containing the SERVFAIL message, to downstream clients. The length of the list of top queries, the time period for the report, and other parameters are specified using filters. The default dashboard displays the top 10 query names within the last 24 hours. When capturing queries, the Grid member matches authoritative and recursive queries to generate events for the report. This dashboard displays no DNS client information, or the identities of impacted name servers, when the SERVFAIL originates from an upstream server.

DNS Top SERVFAIL Errors Received

The DNS Top SERVFAIL Errors Received dashboard lists the top queries resulting in Infoblox name servers receiving DNS response packets containing the SERVFAIL message from upstream name servers.

The default dashboard displays the top upstream query names within the last 24 hours. (The upstream query name may be a query name supplied by a client, or another name that is needed while processing a client query.) When capturing queries, the Grid member matches recursive queries to generate events for the report. This dashboard displays no DNS client information or the identities of impacted name servers. This dashboard reflects the exact numeric value of the number of queries.

DNS Top Timed-out Recursive Queries

The DNS Top Timed-out Recursive Queries dashboard shows the number of queries sent to Infoblox Grid member name servers, which result in timeouts after sending recursive queries to upstream name servers.
