Measures reported by SWSDNSCacheTest

The SWSDNSCacheTest provides DNS cache statistics for the process of the instance. The DNS cache caches IP addresses and DNS names. Web Server uses DNS caching for logging and for access control by IP address.

 The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
No_of_Cache_Hits Indicates the number of cache hits during last measurement period. Number  
No_of_Cache_Misses Indicates the number of cache misses during last measurement period. Number  
Hit_Ratio Indicates the number of cache hits compared to the number of cache lookups. Percent  
Async_Lookups_Enabled Indicates whether the asynchronous Lookups is enabled or disabled. boolean  
Lookups_In_Progress Indicates whether the current number of lookups is in progress. Number  
Async_Name_Lookups Indicates the number of forward lookups that have occured during last measurement period. Number  
Async_Addr_Lookups Indicates the number of reverse lookups that have occured during last measurement period. Number  
DNS_Cache_Enabled Indicates whether the asynchronous DNS cache is enabled or disabled. boolean Async DNS enabled/disabled displays whether the server uses its own asynchronous DNS resolver instead of the operating system's synchronous resolver. By default, Async DNS is disabled.
