Find switch ports in script

[greensmith]

Hello,

I have been attempting to use nxshell and a script to iterate through each object in my network and tell me switch port information.

However I am stuck at using the ConnectionPoint class and findConnectionPoint.
https://www.netxms.org/documentation/javadoc/latest/org/netxms/client/topology/class-use/ConnectionPoint.html

import org.netxms.client

for node in [o for o in s.getAllObjects() if isinstance(o, objects.Node)]:
	NXCSession.findConnectionPoint(node.ZONE0, node.getPrimaryIP())

the code errors out with the following TypeError: findConnectionPoint(): self arg can't be coerced to org.netxms.client
.NXCSession

Trying to use macAddr or just ObjectId complains that it requires 2-3 arguments rather than just 1.

Has anyone else successfully used findConnectionPoint or have any tips to point me in the right direction?

You are trying to call static method — code should be like this:

for node in [o for o in s.getAllObjects() if isinstance(o, objects.Node)]:
	point = s.findConnectionPoint(node.ZONE0, node.getPrimaryIP())
	print node.getObjectName(), point

And you don't need to import org.netxms.client, it's done automatically by nxshell.

from org.netxms.client import *
from org.netxms.api.client import *

Thanks Alex, that works

for anyone else interested in this, here is the code i used.

it checks the ip address of each node - if it matches regex (i am only interested in nodes from one subnet) it prints the data in csv format...
NAME,IP,MAC,SWITCH,PORT,DIRECTLYCONNECTED

import re
import csv
import sys

w = csv.writer(sys.stdout, dialect='excel')
w.writerow(['NAME', 'IP', 'MAC', 'SWT', 'PORT', 'DIR'])

for node in [o for o in s.getAllObjects() if isinstance(o, objects.Node)]:
	#set node information
	#convert ip to string and remove slash
	vnodeIp = str(node.getPrimaryIP())
	vnodeIp = vnodeIp.replace("/","")
	vnodeName = node.getObjectName()
	vnodeMac = node.getPrimaryMAC()

	#regex to match anything in .2. subnet
	subnetRegex = re.match("^\d{1,3}\.\d{1,3}\.2\.\d{1,3}$",vnodeIp)

	#if in this subnet run...
	if subnetRegex:

		#get connectionpoint
		point = s.findConnectionPoint(node.ZONE0, node.getPrimaryIP())

		#handle connectionpoint data exceptions
		try:
			vswitchID = s.getObjectName(point.nodeId)
		except:
			vswitchID = "null"
		try:
			vportID = s.getObjectName(point.interfaceId)
		except:
			vportID = "null"
		try:
			vdirCon = point.directlyConnected
		except:
			vdirCon = "False"

		#print data
		w.writerow([
			vnodeName,
			vnodeIp,
			vnodeMac,
			vswitchID,
			vportID,
			vdirCon
		])

Again, thanks for the help!
