Help sought with code not displaying events

We are running Zenoss 5.1.1.

We have a script that is supposed to get information regarding an event. However, right now all we are getting is UNKNOWN.

One problem is that I am not certain that the code I am looking at is the code that is executing. I am in the zenhub looking at the code that supposedly is executing. However, I added a print line so I could know that the code is running - and I don't see that line.

I created a snapshot, commited that snapshot, then did a restart of the zenhub. I still don't see the change.

Here's the code I am executing:

#!/usr/bin/env python
# disponeevent.py - Display one Zenoss event by eventKey
# disponeevent.py

import sys

#print 'Number of arguments:', len(sys.argv), 'arguments.'
#print 'Argument list:', str(sys.argv)

# import the stuff that zendmd needs and create the dmd context

import Globals
from Products.ZenUtils.ZenScriptBase import ZenScriptBase
from transaction import commit
dmd = ZenScriptBase(connect=True, noopts=True).dmd

# import the stuff that zep needs
from Products.Zuul import getFacade, listFacades
from zenoss.protocols.jsonformat import from_dict
from zenoss.protocols.protobufs.zep_pb2 import EventSummary
from Products.ZenEvents.events2.proxy import EventSummaryProxy

# create a context for the sync function
sync = dmd.zport._p_jar.sync

# create the zep context
zep = getFacade('zep')

# create an event filter to only fetch events with
# a status of 0 or 1 (new or acknowledged)
zep_filter = zep.createEventFilter(event_key=sys.argv[1])
#print 'zep_filter: %s' % (zep_filter)

# fetch the events from zep using the filter we just created
for summary in zep.getEventSummariesGenerator(filter=zep_filter):

# synchronize each cycle for good measure
sync()

# create the event context so that the event can be
# queried/manipulated as you would in an event transform
# this is done using an event proxy
evt = EventSummaryProxy(from_dict(EventSummary, summary))

# print some information about the event
print 'DaveH display of events'
print 'eventKey: %s' % (evt.eventKey)
print 'Device: %s' % (evt.device)
print 'eventState: %s' % (evt.eventState)
print 'firstTime: %s' % (evt.firstTime)
print 'severity: %s' % (evt.severity)
print 'eventClass: %s' % (evt.eventClass)
print 'lastTime: %s' % (evt.lastTime)
print 'Summary: %s' % (evt.summary)
print 'message: %s' % (evt.message)

# create an event filter to use when acknowledging,
# closing, or reopening a single event (set based on evt.evid)
evid_filter = zep.createEventFilter(uuid=[evt.evid])

We are seeing everything EXCEPT the DaveH line - which I just tried to add this morning.

1. Why would I not be getting information in the evt.attributes

2. Why would I not be seeing the DaveH print line

Thank you
