how to monitor localhost network socket traffic that does not go
through a physical interface?
for example, we run the server Apache + JServe on Solaris. I can use
Solaris's "snoop" to diagnose traffic from apache to the outside, but
i if i use snoop to monitor the port Jserve is using to communicate
with Apache, snoop returns nothing.
i don't know much about unix sockets, but i suspect this is because
snoop only capture traffics that goes thru the physical network
What really happens in my case is that browser stalls in the middle of
a particular web page in a site using our in-house application server
that involves apache + jserv and an in-house application server. I can
see when packets stalls between host and the browser client, but i
need to see which one of these application is responsible for the
stalling. So if i can see the traffic between Apache and JServe, or
between JServe and inhouse-server, that'll pinpoint my problem.
few weeks ago i learned about lsof here, but haven't studied it yet.
Would lsof be useful?
PS what's snoop equivalent in linux?
