socket performance

[wvsa]

Good day all,

Are there any tools, utilities that I can measure socket performance/activity. As a followup question is there a way to determine if a socket port is down/unavailable? Thankyou in advance for your input.

You can use:

# netstat -an
# lsof

We would like to be able to measure network activity going through a socket port on a hourly basis. If there is a way to be alerted if traffic going through a particular port has been stopped or hung, we would greatly appeciate any input.

Hi,

Maybe you could find "tcpdump" utility useful ( I have not tested it but looks fine ).

Hope this helps.
Kind regards,
Zigor
