Hello

I'm debugging an application than listens on an UDP (unprivileged)
port and I'm suspecting a queue buildup at certain peak load times. I
need to monitor the status of a particular input queue (how many
packets/bytes are waiting for service) at a certain moment.

I investigated netstat and ndd but haven't found anything useful. I recall
being able to do this on Tru64's and Linux' versions of netstat, but
on Solaris I'm stuck.

Does anybody have any experience on this one?

TIA,
cl.

Claudio--

Some this might be obvious and already tried (or not):

Tried 'snoop' or the current Ethereal? The Ethereal 0.9.16 GUI has a
pretty cool "conversation list" feature that will break down network and
transport conversation stats b/w hosts.

'netstat -s -P udp' or 'netstat -a -P udp'.

'kstat' on Solaris 8/9 will produce related kernel stats but you'll have
to figure out what you want to look at. 'netstat -k'

'lsof' (opensource, not included in Solaris) with "-i udp" might also
get you what you're looking for.
