I can observe the same phenomena on FreeBSD 10.2: current+cache==total==USED+FREE. There must be some relationship between them.
$ netstat -mb|grep "mbuf clusters" 0/766/766/126146 mbuf clusters in use (current/cache/total/max) $ vmstat -z|egrep "mbuf_cluster|ITEM"|column -t ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP mbuf_cluster: 2048, 126146, 759, 7, 759, 0, 0 -----Original Message----- From: owner-freebsd-...@freebsd.org [mailto:owner-freebsd-...@freebsd.org] On Behalf Of Hooman Fazaeli Sent: 2015年12月2日 0:06 To: freebsd-net@freebsd.org Subject: mbuf statistics Hi, On an idle freebsd 9.3 system: > vmstat -z | egrep "mbuf_cluster|ITEM" | column -t ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP mbuf_cluster: 2048, 10284, 1152, 56, 4237, 0, 0 > netstat -mb | grep "mbuf clusters in use" 512/696/1208/10284 mbuf clusters in use (current/cache/total/max) one can see that: current + cache == total == USED + FREE but the current/cache values as reported by netstat are very different form USED/FREE values reported by vmstat, so they should have different meaning. The question is: what is the exact meaning of USED/FREE and current/cache values? Is there any relationship between them? -- Best regards Hooman Fazaeli _______________________________________________ freebsd-net@freebsd.org mailing list https://na01.safelinks.protection.outlook.com/?url=https%3a%2f%2flists.freebsd.org%2fmailman%2flistinfo%2ffreebsd-net&data=01%7c01%7chonzhan%40064d.mgd.microsoft.com%7c23b4f4abbceb4f717fba08d2fa695134%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=dprvahDUYdoMYi22nOHMes385ngc4gJ6SH8aHX8LHiA%3d To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
