About GTM and DNS rate-limited license statistics

If you have a BIG-IP GTM or DNS Services rate-limited license, BIG-IP displays statistics about the rate limits including Effective Rate Limit (RPS), Object Count, and Rate Rejects. Rate limit statistics are displayed separately for Global Traffic Management and DNS.

Viewing rate-limited license statistics

Ensure that the BIG-IP system has a rate-limited license.
View statistics about GTM and DNS Services licensed service rates to help you determine when to upgrade your license.
  1. On the Main tab, click Statistics > Module Statistics > DNS > Delivery. The DNS Delivery statistics screen opens.
  2. From the Statistics Type list, select Profiles.
  3. In the Global Profile Statistics area, in the Details column of the DNS profile, click View.
  4. In the DNS 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 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 Expresszones, DNS cache resolvers, and DNSSEC zones.
    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.
  5. 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 GTM system handles based on the rate-limited license installed on the system.
    Object Count The sum of these objects configured on the GTM system: data centers, wide IPs, wide IP aliases, servers, GTM pools, GTM pool members, virtual servers, GTM iRules, and topology records.
    Rate Rejects The number of DNS requests that the GTM system has rejected based on the rate limit of the license installed on the system.
    Tip: The GTM 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 GTM 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.
