You can get a good + fast total connection count from /proc/slabinfo: egrep '^(nf_conntrack_|ip_vs_conn)' /proc/slabinfo Look at column 2, the first column with numbers. Compare the numbers to cat /proc/sys/net/nf_conntrack_max cat /sys/module/ip_vs/parameters/conn_tab_bits The conntrack_max is a HARD limit of the number of conntracks the system can have. 2^conn_tab_bits for IPVS is the size of the ipvs tracking table - I'm not sure whether that is a hard limit, or just a hash bucket sizing which permits chaining. best regards Patrick _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [email protected] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
