add(event, opts = {}) click to toggle source

Adds an external event to the internal audit log.

This is intended for integration with external systems that detect or produce events relevant for the administrator of the system. For example, an external monitoring tool may be able to detect that a file system is full inside the guest operating system of a virtual machine. This event can be added to the internal audit log sending a request like this:

source

POST /ovirt-engine/api/events <event>

<description>File system /home is full</description>
<severity>alert</severity>
<origin>mymonitor</origin>
<custom_id>1467879754</custom_id>

</event>


Events can also be linked to specific objects. For example, the above event could be linked to the specific virtual machine where it happened, using the `vm` link:

source

POST /ovirt-engine/api/events <event>

<description>File system /home is full</description>
<severity>alert</severity>
<origin>mymonitor</origin>
<custom_id>1467879754</custom_id>
<vm id="aae98225-5b73-490d-a252-899209af17e9"/>

</event>


NOTE: When using links, like the `vm` in the previous example, only the `id` attribute is accepted. The `name` attribute, if provided, is simply ignored.

@param event [Event] The `event` to add.

@param opts [Hash] Additional options.

@option opts [Hash] :headers ({}) Additional HTTP headers.

@option opts [Hash] :query ({}) Additional URL query parameters.

@option opts [Integer] :timeout (nil) The timeout for this request, in seconds. If no value is explicitly

given then the timeout set globally for the connection will be used.

@option opts [Boolean] :wait (true) If `true` wait for the response.

@return [Event]

# File lib/ovirtsdk4/services.rb, line 6974
def add(event, opts = {})
  internal_add(event, Event, ADD, opts)
end
event_service(id) click to toggle source

Reference to the service that manages a specific event.

@param id [String] The identifier of the `event`.

@return [EventService] A reference to the `event` service.

# File lib/ovirtsdk4/services.rb, line 7156
def event_service(id)
  EventService.new(self, id)
end
list(opts = {}) click to toggle source

Get list of events.

source

GET /ovirt-engine/api/events


To the above request we get following response:

</event>

</events>


The following events occur:

  • id=“1” - The API logs in the admin user account.

  • id=“2” - The API logs out of the admin user account.

@param opts [Hash] Additional options.

@option opts [Boolean] :case_sensitive Indicates if the search performed using the `search` parameter should be performed taking case into

account. The default value is `true`, which means that case is taken into account. If you want to search
ignoring case set it to `false`.

@option opts [Integer] :from Indicates the identifier of the the first event that should be returned. The identifiers of events are

strictly increasing, so when this parameter is used only the events with that identifiers equal or greater
than the given value will be returned. For example, the following request will return only the events
with identifiers greater or equal than `123`:

[source]
----
GET /ovirt-engine/api/events?from=123
----

This parameter is optional, and if not specified then the first event returned will be most recently
generated.

@option opts [Integer] :max Sets the maximum number of events to return. If not specified all the events are returned.

@option opts [String] :search The events service provides search queries similar to other resource services.

We can search by providing specific severity.

[source]
----
GET /ovirt-engine/api/events?search=severity%3Dnormal
----

To the above request we get a list of events which severity is equal to `normal`:

[source,xml]

A virtualization environment generates a large amount of events after
a period of time. However, the API only displays a default number of
events for one search query. To display more than the default, the API
separates results into pages with the page command in a search query.
The following search query tells the API to paginate results using a
page value in combination with the sortby clause:

[source]
----
sortby time asc page 1
----

Below example paginates event resources. The URL-encoded request is:

[source]
----
GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%201
----

Increase the page value to view the next page of results.

[source]
----
GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%202
----

@option opts [Hash] :headers ({}) Additional HTTP headers.

@option opts [Hash] :query ({}) Additional URL query parameters.
