# This handles incoming unsolicited alerts over the network. For the moment
|
|
# we'll link into ipmi.py to do PET alerts, with the assumption that more
|
|
# typical .mib based handling will be used for other events and confluent's
|
|
# event service is to handle the peculiarities of an IPMI PET. In the future
|
|
# it may make sense to extend this in a more general case, but that rework can
|
|
# be deferred for now.
|
|
|
|
# Phase 1 is to be facilitating some application doing http calls to get help
|
|
# decoding data.
|
|
|
|
# Phase 2 is to be able to bind a port and have snmptrapd just forward the
|
|
# packet rather than have something block snmptrapd at all for things confluent
|
|
# can handle.
