NetXMS Support Forum

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!
