    Effective Rate Limit (RPS)
    The number of DNS name resolution requests per second the BIG-IP system handles based on the rate-limited license installed on the system.
    Object Count
    The sum of these objects configured on the BIG-IP system: DNS Express zones, DNS cache resolvers, and DNSSEC zones.

  47. In the DNS area, view the
    Rate Limit (RPS)
    and
    Rate Rejects
    statistics.
    Statistic type
    Description
    Rate Limit (RPS
    )
    The number of DNS name resolution requests per second the BIG-IP system handles based on the rate-limited license installed on the system.
    Rate Rejects
    The number of DNS requests that the BIG-IP system has rejected based on the rate limit of the license installed on the system.
  48. In the Global Traffic Management area, view the
    Effective Rate Limit (RPS)
    ,
    Object Count
    , and
    Rate Rejects
    statistics.
    Statistic type
    Description
    Effective Rate Limit (RPS)
    The number of DNS name resolution requests per second the BIG-IP DNS system handles based on the rate-limited license installed on the system.
    Object Count
    The sum of these objects configured on the BIG-IP DNS system: data centers, wide IPs, wide IP aliases, servers, pools, pool members, virtual servers, iRules, and topology records.
    Rate Rejects
    The number of DNS requests that the BIG-IP DNS system has rejected based on the rate limit of the license installed on the system.
    The BIG-IP DNS license includes the DNS Services license. Global traffic management requests (requests for wide IPs) are a subset of DNS requests. Therefore, when the number of requests that BIG-IP DNS receives for a wide IP exceeds the DNS Services rate limit, the
    Rate Rejects
    count for DNS increments, rather than the
    Rate Rejects
    count for Global Traffic Management incrementing.
