About Pool Memory

Pool means group of nodes.   GLOBAL_STATISTIC_MEM_POOL_USED means the total memory in use.     If I create serveral pools, does GLOBAL_STATISTIC_MEM_POOL_USED mean the sums of each ...

This is an issue of semantics. In the case of global statistics, the term MEM POOL refers to a internal pool of memory, not a load balancing pool. The system allocates a chunk of internal memory that it uses for configuration storage, connection state tables, and load balancing decisions. This chunk of memory is called the global memory pool.

 

 

The GLOBAL_STATISTIC_MEM_POOL_TOTAL statistic is the amount of memory that BIG-IP allocates from the system (I believe it is somewhere around 90% of the physical memory of the device).

 

 

The GLOBAL_STATISTIC_MEM_POOL_USED statistic refers to the amount of that memory pool that is currently in use. This could be used to help determine the capacity of the device with regards to it's ability to store larger configurations and maintain larger connection states.

 

 

Hope this clears things up a bit...
