'evt' is the event. Here's a bit of a walk-through
#if the index is given from the event, set the index to it
index = getattr(evt, 'ifIndex', 0)
#it sets the descr to the description of the interface if that's what
is creating the event.
descr = getattr(evt, 'ifDescr', 'Unknown Interface')
#then it sets the event component to the interface
evt.component = descr
#if there is a device associated with the event
if device:
#we set the description blank
description = ''
#and check the interfaces on the device
for iface in device.os.interfaces():
#if the iterated index matches from the event
if index and iface.ifindex == index:
#we set the description to the interface description
descr = iface.description
#or else we check if the interface name and descr match
elif descr and iface.name == descr:
#and get the description off of the interface
descr = iface.description
#and then we set the event summary
evt.summary = 'Link down on %s' % (descr)
The formatting is all wrong, but hopefully it's a little clearer
(opaque mud?).
