[zenoss-users] 'Event' object has no attribute. dotted decimal IPv6 -> hex

[gentux31]

Dear all,

I want to transform a bgpBackwardTransition with a dotted decimal IPv6 address to the normal hex addres. I wrote a python script that I call from the event transform. This is my event transform:


Code:

from socket import gethostbyaddr
from decToHex import *

for attr in dir(evt):
        if attr.startswith('1.3.6.1.2.1.15.3.1.14.'):
            evt.bgpPeerIp = attr.replace('1.3.6.1.2.1.15.3.1.14.', '')
            if len(evt.bgpPeerIp) > 15:
                evt.bgpPeerIp = printIPv6(evt.bgpPeerIp)
            try:
                evt.bgpPeerName = gethostbyaddr(evt.bgpPeerIp)[0]
            except:
                pass
            evt.summary = "bgpBackwardTransNotification from " + evt.bgpPeerIp + " (" + evt.bgpPeerName + ")"




In zentrap.log I can see the following:

ERROR zen.Events: Error transforming EventClassInst bgpBackwardTransition ('Event' object has no attribute 'bgpPeerName')

But I don't know why it complains about the event object not having the attribute bgpPeerName. I just created it saying:

evt.bgpPeerName = gethostbyaddr(evt.bgpPeerIp)[0]

Just to share here is the decToHex code:

Code:

import string
import sys
from IPy import IP

def printIPv6(ip):
        """Print the IPv6 address"""
        array_ip = ip.split('.')
        i = 0
        ipv6_address = ""
        while i < 14:
                ipv6_address = ipv6_address + decToHex(array_ip[i], array_ip[i+1]) + ":"
                i = i+2
        ipv6_address = ipv6_address + decToHex(array_ip[14], array_ip[15])
        return ipv6_address

def toHex(i):
        """Convert an int into a hex string (without the leading 0x)"""
        return hex(i)[2:]

def decToHex(a, b):
        """Convert a decimal dotted IPv6 addresses to a regular/hexadecimal IPv6 address"""
        if int(a) == 0:
                if int(b) == 0:
                        return toHex(int(a))
                else:
                        return toHex(int(b))
        elif (int(b)) < 10:
                return toHex(int(a)) + "0" + toHex(int(b))
        else:
                return toHex(int(a)) + toHex(int(b))




Any thought on how to fix this? Because the event transform is not working. Thanks all!
