Application ports monitoring

[yc_2]

Hi,

There is this intermmittent disconnection from user's PC accessing Oracle Financial Application using form in HP server.

The PC is running XP and the HP server (rp4440; HP-UX11i) is in different network segment.

How do I monitor the application port availability end-to-end continuously?


Thanks in advance,
YC

hi,

hope i understand u correctly.

from the user's workstation, run:

c:\> netstat -a 3 > spool_netstat_client.txt
for every tcp and udp port at 3 seconds interval spool into file, spool_netstat_client.txt

for tcp, use "-p tcp" option.

netstat /? - for more info

from the HP server, run netstat command as well to check:

# netstat -an|grep -i listen > spool_netstat_svr.txt
and
# netstat -an|grep -i estab > spool_netstat_svr.txt
if possible, grep the port of the application, i.e. servlet or server based port.


regards.

On the server end, check the status of the port for the said application .

On the client end, check for the same port using

netstat -p tcp -a 2

Redirect the output t a file. Especially check this as soon as you face a disconnect .

Otherwise, you can use certain network monitoring tools from the client to check the status of the port on which the application is listening on the server .

Understand the approach recommended will captured the disconnection once it occur.

If the problem is from the network devices, is there a way to track the problem source from PC end or the server end?
