Public bug reported: This is a follow up from some summit discussions between the searchlight and nova teams to note discrepancies between the nova API and notification payloads. The reason this causes us some issues is that at scale it becomes far simpler to treat notifications as a complete record of a servers's state rather than updating individual fields. At the present time we contact nova's API for some notification events to get that complete record.
An example API response to retrieve a server's information is at http://paste.openstack.org/show/xbv2CwtHnhhl1nLLiJeN/ An example compute.create.end notification is at http://paste.openstack.org/show/zG5aJeUpC3LAGr0J0P2T/ An example compute.update.end notification is at http://paste.openstack.org/show/uwh1izVsaW5eg7zDrgFm/ I'll break these into multiple bug reports since some of the fields pose more difficulties. The fields missing from both create and update notifications that I think will be easier to add are: * tags * description * key_name * locked * OS-DCF:diskConfig (some extensions are mapped to alternate field names, but this one and possibly some others are not) I'm running devstack with it and all services from master as of Oct 28 2016, API microversion 2.35. ** Affects: nova Importance: Undecided Status: New ** Tags: searchlight -- You received this bug notification because you are a member of Yahoo!
