NAT pools usage

Hi all, 

Can anyone let me know how to check how full of my IP pools are?

I am a bit confusing for the output of "diagnose firewall ippool list" and "diagnose firewall ippool stats "

In my case, for example :

# diagnose firewall ippool stats  Total 8 ippools are allocated. Total 5807 client hosts are online. Total 99 natip(s) are allocated. Total 5904 PBA(s) are allocated. Approximate 5 PBA(s) are allocated in 1 second before.

diagnose firewall ippool list ippool Eduroam-NAT: id=4, block-sz=512, num-block=1, fixed-port=no, use=10608 ip-range=130.102.13.2-130.102.13.127 start-port=5117, num-pba-per-ip=118

Does it show the usage from the output above? Also, what is the meaning of "use=10608"?
