Is there an easy way to get a count of the number of active socket
connections, or even better, number of socket connections in the time_wait
state? (Something lightweight... under /proc/sys/net/ipv4/? I'd like to avoid
the impact of listing out all the connections a-la netstat.)
[dag@rhun ~]$ dstat -t --tcp

Although it is using /proc/net/tcp
You can use --debug to see how much time in milliseconds dstat spends on
getting that information. Of course that number is impacted by the load on
the system as well.
[dag@rhun ~]$ dstat -t --tcp --debug
Module dstat_time
Module dstat_tcp requires ['/proc/net/tcp', '/proc/net/tcp6']
