I think socket info should be groupped together: 2407/1058/3465 mbufs in use (current/cache/total) 1117/797/1914/98304 mbuf clusters in use (current/cache/total/max) 1117/90 mbuf+clusters out of packet secondary zone in use (current/cache) 761/417/1178/0 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/0 9k jumbo clusters in use (current/cache/total/max) 0/0/0/0 16k jumbo clusters in use (current/cache/total/max) 5879K/3526K/9406K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 15333/15537/30870/204800 socket UMA in use (current/cache/total/max) 5929K bytes allocated to socket 0 request for socket UMA denied 104/264/6656 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 135834 requests for I/O initiated by sendfile 0 calls to protocol drain routines Second, I think socket memory calculation should include tcpcb, udpcb, inpcb, unpcb and probably tcptw items. -- Igor Sysoev http://sysoev.ru/en/
