Recently I needed to find out who is connecting to an Oracle database and at the same time I wanted to see the load the specific connection add to the CPU. So in short I needed IP Address and Port tied to a Unix Pid.

I wrote this quick and dirty python script.

#!/usr/bin/python
import subprocess

## No doubt you would want to exclude some non local or expected IP addresses
excludeIPs="10.2.16.86|10.2.16.62|10.2.16.83|\*.\*"

p = subprocess.Popen("/usr/bin/netstat -an | grep 1521 | awk '{print $2}' | egrep -v '" + excludeIPs + "'", stdout=subprocess.PIPE, shell=True)
nonlocals= p.stdout

if nonlocals <> '':
  p = subprocess.Popen("pfiles `ls /proc` 2>/dev/null", stdout=subprocess.PIPE, shell=True)
  try:
    outs, errs = p.communicate()
  except TimeoutExpired:
    p.kill()
    outs, errs = p.communicate()

  pfiles = outs

  for line in nonlocals:
    line=line.strip()
    (IP,port) = line.rsplit('.',1)
    print ("Going to find PID for connection with IP %s and port %s" % (IP,port) )

    for line in pfiles.splitlines():
      if line[:1].strip() <> '':
        pid = line
      if "port: " + port in line:
        print pid

I plan to enhance this script a little bit but for now it did exactly what I needed.
