Hi there, I'm trying to write a patch for collectd to generate trend graphs on ipv4 and ipv6 statistics.
I use the sysctls net.inet.ip.stats and net.inet6.ip6.stats for this. The structs I use to parse these sysctls are "struct ipstat" and "struct ip6stat". While doing this, I keep running into the fact that the "struct ipstat.ips_total" count seems to be twice the number of ipv4 packets that actually got received on a host. Does this make any sense at all? So, in other words, if I call "sysctls net.inet.ip.stats", and do another call 1 second later, I can deduce a per-second incoming ipv4 packet rate. This seems to be twice as high as actually happening. The number reported in struct ip6stat.ip6s_total seems to be correct. Is there any reason for the ips_total to be twice the number of ipv4 packets that actually got received? Another way to witness these counts is by doing: netstat -s -p ip, and then checkout "total packets received" on a per-second basis. Thank you very much in advance!
