While a Sample represents a single numeric datapoint, driving a Meter +that represents the changes in that value over time, an Event represents the +state of an object in an OpenStack service (such as an Instance in Nova, or +an Image in Glance) at a point in time when something of interest has occurred. +This can include non-numeric data, such as an instance's flavor, or network +address. + +In general, Events let you know when something has changed about an +object in an OpenStack system, such as the resize of an instance, or creation +of an image. + +While Samples can be relatively cheap (small), +disposable (losing an individual sample datapoint won't matter much), +and fast, Events are larger, more informative, and should be handled more +consistently (you do not want to lose one). + +Event Structure +=============== + +Events contain the following information: + +event_type + A dotted string defining what event occured, such as "compute.instance.resize.start" + +message_id + A UUID for this event. + +generated + A timestamp of when the event occurred on the source system. + +traits + A flat mapping of key-value pairs. + The event's Traits contain most of the details of the event. Traits are + typed, and can be strings, ints, floats, or datetimes. + + +Events from Notifications +========================= + +Events are primarily created via the notifications system in OpenStack. +OpenStack systems, such as Nova, Glance, Neutron, etc. will emit +notifications in a JSON format to message queue when some notable action is +taken by that system. Ceilometer will consume such notifications from the +message queue, and process them. + +The general philosophy of notifications in OpenStack is to emit any and all +data someone might need, and let the consumer filter out what they are not +interested in. In order to make processing simpler and more efficient, +the notifications are stored and processed within Ceilometer as Events. +The notification payload, which can be an arbitrarily complex JSON data +structure, is converted to a flat set of key-value pairs known as Traits. +This conversion is specified by a config file, so that only the specific +fields within the notification that are actually needed for processing the +event will have to be stored as Traits. + +Note that the Event format is meant for efficient processing and querying, +there are other means available for archiving notifications (i.e. for audit +purposes, etc), possibly to different datastores. + +Converting Notifications to Events +---------------------------------- + +In order to make it easier to allow users to extract what they need, +the conversion from Notifications to Events is driven by a +configuration file (specified by the flag definitions_cfg_file_ in +ceilometer.conf). + +This includes descriptions of how to map fields in the notification body +to Traits, and optional plugins for doing any programmatic translations +(splitting a string, forcing case, etc.) + +The mapping of notifications to events is defined per event_type, which +can be wildcarded. Traits are added to events if the corresponding fields +in the notification exist and are non-null. (As a special case, an empty +string is considered null for non-text traits. This is due to some openstack +projects (mostly Nova) using empty string for null dates.) + +If the definitions file is not present, a warning will be logged, but an empty +set of definitions will be assumed. By default, any notifications that +do not have an event definition in the definitions file for them will be +converted to events with a set of minimal, default traits. This can be +changed by setting the flag drop_unmatched_notifications_ in the +ceilometer.conf file. If this is set to True, then any notifications +that don't have events defined for them in the file will be dropped. +This can be what you want, the notification system is quite chatty by design +(notifications philosophy is "tell us everything, we'll ignore what we don't +need"), so you may want to ignore the noisier ones if you don't use them. + +.. _definitions_cfg_file: configuration.html#event-conversion +.. _drop_unmatched_notifications: configuration.html#event-conversion + +There is a set of default traits (all are TEXT type) that will be added to +all events if the notification has the relevant data: + +* service: (All notifications should have this) notification's publisher +* tenant_id +* request_id + +These do not have to be specified in the event definition, they are +automatically added, but their definitions can be overridden for a given +event_type. + +Definitions file format +----------------------- + +The event definitions file is in YAML format. It consists of a list of event +definitions, which are mappings. Order is significant, the list of definitions +is scanned in *reverse* order (last definition in the file to the first), +to find a definition which matches the notification's event_type. That +definition will be used to generate the Event. The reverse ordering is done +because it is common to want to have a more general wildcarded definition +(such as "compute.instance.*" ) with a set of traits common to all of those +events, with a few more specific event definitions (like +"compute.instance.exists") afterward that have all of the above traits, plus +a few more. This lets you put the general definition first, followed by the +specific ones, and use YAML mapping include syntax to avoid copying all of the +trait definitions. + +Event Definitions +----------------- + +Each event definition is a mapping with two keys (both required): + +event_type + This is a list (or a string, which will be taken as a 1 element + list) of event_types this definition will handle. These can be + wildcarded with unix shell glob syntax. An exclusion listing + (starting with a '!') will exclude any types listed from matching. + If ONLY exclusions are listed, the definition will match anything + not matching the exclusions. +traits + This is a mapping, the keys are the trait names, and the values are + trait definitions. + +Trait Definitions +----------------- + +Each trait definition is a mapping with the following keys: + +type + (optional) The data type for this trait. (as a string). Valid + options are: *text*, *int*, *float*, and *datetime*. + defaults to *text* if not specified. +fields + A path specification for the field(s) in the notification you wish + to extract for this trait. Specifications can be written to match + multiple possible fields, the value for the trait will be derived + from the matching fields that exist and have a non-null values in + the notification. By default the value will be the first such field. + (plugins can alter that, if they wish). This is normally a string, + but, for convenience, it can be specified as a list of + specifications, which will match the fields for all of them. (See + `Field Path Specifications`_ for more info on this syntax.) +plugin + (optional) This is a mapping (For convenience, this value can also + be specified as a string, which is interpreted as the name of a + plugin to be loaded with no parameters) with the following keys + + name + (string) name of a plugin to load + + parameters + (optional) Mapping of keyword arguments to pass to the plugin on + initialization. (See documentation on each plugin to see what + arguments it accepts.) + +Field Path Specifications +------------------------- + +The path specifications define which fields in the JSON notification +body are extracted to provide the value for a given trait. The paths +can be specified with a dot syntax (e.g. "payload.host"). Square +bracket syntax (e.g. "payload[host]") is also supported. In either +case, if the key for the field you are looking for contains special +characters, like '.', it will need to be quoted (with double or single +quotes) like so: + + payload.image_meta.'org.openstack__1__architecture' + +The syntax used for the field specification is a variant of JSONPath, +and is fairly flexible.
