You can check for the cache size using the below commad: show recursion_cache_size.
A DNS server caching a record will return the TTL after reducing the time the record was cached by the server. If the Original TTL of the record is X seconds and a query is received after y seconds of caching, the caching server will return a TTL of (x-y)

Sorry for replying on an old topic, but that command doesn't give me any output. It also didn't gave me any error so the command is good I guess, but why doesn't it show any output ?
I want to see the cache size of a virtual Infoblox member V1425 (Nios 8.4.8).
Does anyone has any numbers for this device ?
Also does anyone know how I can see what the amount of cache size usage is currently and over time ? Is there any reporting dashboard for that ?
I know there is a cache hit ration, but that is not what I am looking for. I need to know how much percentage of the cache size is in use, preferably selectable in real time and over a period of time
Regards,
Stefan

Hello Stefan,
It will show you the values only if you explicitly define the cache size first.
set recursion_cache_size <view name> <size>
show recursion_cache_size
