This information becomes useful to an admin for audit purposes. Tacker Resources supporting Events ---------------------------------- As of Newton release, events information is captured for below: - VNF - VNFD - VIM Tacker supported event types ---------------------------- Below are the event types that are currently supported: - CREATE - DELETE - MONITOR - SCALE - UPDATE The above can be used as filters when listing events using tacker client. Accessing Events ---------------- Tacker supports display of events to an end user via - Horizon UI - a separate events tab per resource displays associated events. - Tacker Client - supports below commands: - event-show: Show detailed info for a given event ID. - events-list: Lists all events for all resources. - vim-events-list: List events that belong to a given VIM. - vnf-events-list: List events that belong to a given VNF. - vnfd-events-list: List events that belong to a given VNFD. NOTE: For more details on the syntax of these CLIs, refer to `Tacker CLI reference guide `_ Tacker Client command usage examples to access resource lifecycle events ------------------------------------------------------------------------ 1. The following command displays all the state transitions that occurred on a long running VNF. The sample output illustrates a VNF that has successfully gone through a scale out operation. Note, the here is VNF's uuid. .. code-block:: console tacker vnf-events-list --resource_id +----+---------------+-------------------+-------------------+------------+-------------------+---------------------+ | id | resource_type | resource_id | resource_state | event_type | timestamp | event_details | +----+---------------+-------------------+-------------------+------------+-------------------+---------------------+ | 13 | vnf | 9dd7b2f1-e91e-418 | PENDING_CREATE | CREATE | 2016-09-21 | VNF UUID assigned. | | | | 3-bcbe- | | | 20:12:37 | | | | | 34b80bdb18fb | | | | | | 14 | vnf | 9dd7b2f1-e91e-418 | PENDING_CREATE | CREATE | 2016-09-21 | Infra Instance ID | | | | 3-bcbe- | | | 20:13:09 | created: 3bd369e4-9 | | | | 34b80bdb18fb | | | | ee3-4e58-86e3-8acbb | | | | | | | | dccedb5 and Mgmt | | | | | | | | URL set: {"VDU1": | | | | | | | | ["10.0.0.9", | | | | | | | | "10.0.0.2"], | | | | | | | | "VDU2": | | | | | | | | ["10.0.0.4", | | | | | | | | "10.0.0.5"]} | | 15 | vnf | 9dd7b2f1-e91e-418 | ACTIVE | CREATE | 2016-09-21 | VNF status updated | | | | 3-bcbe- | | | 20:13:09 | | | | | 34b80bdb18fb | | | | | | 16 | vnf | 9dd7b2f1-e91e-418 | PENDING_SCALE_OUT | SCALE | 2016-09-21 | | | | | 3-bcbe- | | | 20:23:58 | | | | | 34b80bdb18fb | | | | | | 17 | vnf | 9dd7b2f1-e91e-418 | ACTIVE | SCALE | 2016-09-21 | | | | | 3-bcbe- | | | 20:24:45 | | | | | 34b80bdb18fb | | | | | +----+---------------+-------------------+-------------------+------------+-------------------+---------------------+ 2.
