From Tanel, previously:


You can run netstat in HP-UX couple of times and calculate how many bytes worth of TCP packets are sent out:  

    netstat -f inet -p tcp


You missed a "couple of times and calculate". Notice that you've got 3.5 billion plus packets in 300 seconds. (Not!).  

So if you want to look at 5 minutes, I'd suggest running the command either twice (at the start and end) and subtracting the numbers,

or maybe 6 times (at the start and each minute) if you'd like a finer grain (you can still subtract the first from the last to get the aggregate over the window).

Or you could use a tool to filter successive runs paired with a time command to spit out the deltas at a finer grain over the window.  

Doing at sanity check on what you reported, you apparently have 3.5 billion packets to send 2 billion bytes, which makes no sense to me, unless they actually do send zero byte packets marked as data for heartbeats somewhere.
