Solaris 10: Seeking per-connection TCP timer values like GNU Linux 'netstat -t -o'



This may be one for Solaris 10 networking gurus. I'm trying to gather some
network connection statistics on a Solaris 10 box, in a zone. I have access to
the global zone if I need to get there to get the data I'm after.

We are troubleshooting an issue, and one of our partners is asking for
per-connection TCP timer data, similar to the output of the GNU/Linux 'netstat
-t -o' (with long options, 'netstat --tcp --timers').

Here's what that output looks like:

Proto Recv-Q Send-Q Local Address Foreign Address
State Timer
tcp 0 0 localhost.localdomain:48404 localhost.localdomain:5053
TIME_WAIT timewait (9.32/0/0)
tcp 0 0 localhost.localdomain:915 localhost.localdomain:32769
ESTABLISHED off (0.00/0/0)
tcp 1 0 xxxxx006:38990 xxxxx006:webcache
CLOSE_WAIT off (0.00/0/0)
tcp 0 0 localhost.localdomain:5053 localhost.localdomain:32799
ESTABLISHED off (0.00/0/0)
tcp 1 0 xxxxx006:40268 xxxxx006:webcache
CLOSE_WAIT off (0.00/0/0)

Note the last "Timer" column, and for the connection in TIME_WAIT state, the
non-zero value for the TCP Wait timer.

So far I've delved into manpages, sunmanagers archives, and wider web
searches, to no avail. My questions are:

1/ Is this TCP timer information exposed on Solaris 10?
2/ If so, how can I get to it, either with an existing tool or
programmatically?

Thank you,
