RE: N/w Bottleneck Check under Benchmark Load ?

["Mark W. Farnham" <mwf@xxxxxxxx>]

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.
